Instead of overwriting them, use `__serialize` and `__unserialize` as extension points which are forward compatible with the new serialization methods in PHP 7.4. * exposed `utf8` Route option, defaults "locale" and "format" in configuration loaders and configurators * added support for invokable service route loaders 4.2.0 ----- * added fallback to cultureless locale for internationalized routes 4.0.0 ----- * dropped support for using UTF-8 route patterns without using the `utf8` option * dropped support for using UTF-8 route requirements without using the `utf8` option 3.4.0 ----- * Added `NoConfigurationException`. * Added the possibility to define a prefix for all routes of a controller via @Route(name="prefix_") * Added support for prioritized routing loaders. * Add matched and default parameters to redirect responses * Added support for a `controller` keyword for configuring route controllers in YAML and XML configurations. 3.3.0 ----- * [DEPRECATION] Class parameters have been deprecated and will be removed in 4.0. * router.options.generator_class * router.options.generator_base_class * router.options.generator_dumper_class * router.options.matcher_class * router.options.matcher_base_class * router.options.matcher_dumper_class * router.options.matcher.cache_class * router.options.generator.cache_class 3.2.0 ----- * Added support for `bool`, `int`, `float`, `string`, `list` and `map` defaults in XML configurations. * Added support for UTF-8 requirements 2.8.0 ----- * allowed specifying a directory to recursively load all routing configuration files it contains * Added ObjectRouteLoader and ServiceRouteLoader that allow routes to be loaded by calling a method on an object/service. * [DEPRECATION] Deprecated the hardcoded value for the `$referenceType` argument of the `UrlGeneratorInterface::generate` method.

So when using PHP to build the RouteCollection, you must make sure to add routes to the sub-collection before adding it to the parent collection (this is not relevant when using YAML or XML for Route definitions). Before: ```php $rootCollection = new RouteCollection(); $subCollection = new RouteCollection(); $rootCollection->addCollection($subCollection); $subCollection->add('foo', new Route('/foo')); ``` After: ```php $rootCollection = new RouteCollection(); $subCollection = new RouteCollection(); $subCollection->add('foo', new Route('/foo')); $rootCollection->addCollection($subCollection); ``` Also one must call `addCollection` from the bottom to the top hierarchy. So the correct sequence is the following (and not the reverse): ```php $childCollection->addCollection($grandchildCollection); $rootCollection->addCollection($childCollection); ``` * [DEPRECATION] The methods `RouteCollection::getParent()` and `RouteCollection::getRoot()` have been deprecated and will be removed in Symfony 2.3. * [BC BREAK] Misusing the `RouteCollection::addPrefix` method to add defaults, requirements or options without adding a prefix is not supported anymore. So if you called `addPrefix` with an empty prefix or `/` only (both have no relevance), like `addPrefix('', $defaultsArray, $requirementsArray, $optionsArray)` you need to use the new dedicated methods `addDefaults($defaultsArray)`, `addRequirements($requirementsArray)` or `addOptions($optionsArray)` instead. * [DEPRECATION] The `$options` parameter to `RouteCollection::addPrefix()` has been deprecated because adding options has nothing to do with adding a path prefix. If you want to add options to all child routes of a RouteCollection, you can use `addOptions()`. * [DEPRECATION] The method `RouteCollection::getPrefix()` has been deprecated because it suggested that all routes in the collection would have this prefix, which is not necessarily true. On top of that, since there is no tree structure anymore, this method is also useless. Don't worry about performance, prefix optimization for matching is still done in the dumper, which was also improved in 2.2.0 to find even more grouping possibilities. * [DEPRECATION] `RouteCollection::addCollection(RouteCollection $collection)` should now only be used with a single parameter. The other params `$prefix`, `$default`, `$requirements` and `$options` will still work, but have been deprecated. The `addPrefix` method should be used for this use-case instead. Before: `$parentCollection->addCollection($collection, '/prefix', [...], [...])` After: ```php $collection->addPrefix('/prefix', [...], [...]); $parentCollection->addCollection($collection); ``` * added support for the method default argument values when defining a @Route * Adjacent placeholders without separator work now, e.g. `/{x}{y}{z}.{_format}`. * Characters that function as separator between placeholders are now whitelisted to fix routes with normal text around a variable, e.g. `/prefix{var}suffix`. * [BC BREAK] The default requirement of a variable has been changed slightly. Previously it disallowed the previous and the next char around a variable. Now it disallows the slash (`/`) and the next char. Using the previous char added no value and was problematic because the route `/index.{_format}` would be matched by `/index.ht/ml`. * The default requirement now uses possessive quantifiers when possible which improves matching performance by up to 20% because it prevents backtracking when it's not needed. * The ConfigurableRequirementsInterface can now also be used to disable the requirements check on URL generation completely by calling `setStrictRequirements(null)`. It improves performance in production environment as you should know that params always pass the requirements (otherwise it would break your link anyway). * There is no restriction on the route name anymore. So non-alphanumeric characters are now also allowed. * [BC BREAK] `RouteCompilerInterface::compile(Route $route)` was made static (only relevant if you implemented your own RouteCompiler). * Added possibility to generate relative paths and network paths in the UrlGenerator, e.g. "../parent-file" and "//example.com/dir/file". The third parameter in `UrlGeneratorInterface::generate($name, $parameters = [], $referenceType = self::ABSOLUTE_PATH)` now accepts more values and you should use the constants defined in `UrlGeneratorInterface` for claritiy. The old method calls with a Boolean parameter will continue to work because they equal the signature using the constants. 2.1.0 ----- * added RequestMatcherInterface * added RequestContext::fromRequest() * the UrlMatcher does not throw a \LogicException anymore when the required scheme is not the current one * added TraceableUrlMatcher * added the possibility to define options, default values and requirements for placeholders in prefix, including imported routes * added RouterInterface::getRouteCollection * [BC BREAK] the UrlMatcher urldecodes the route parameters only once, they were decoded twice before. Note that the `urldecode()` calls have been changed for a single `rawurldecode()` in order to support `+` for input paths. * added RouteCollection::getRoot method to retrieve the root of a RouteCollection tree * [BC BREAK] made RouteCollection::setParent private which could not have been used anyway without creating inconsistencies * [BC BREAK] RouteCollection::remove also removes a route from parent collections (not only from its children) * added ConfigurableRequirementsInterface that allows to disable exceptions (and generate empty URLs instead) when generating a route with an invalid parameter value PK �q�\�3C4� � ! symfony/routing/CompiledRoute.phpnu �Iw�� <?php /* * This file is part of the Symfony package. * * (c) Fabien Potencier <fabien@symfony.com> * * For the full copyright and license information, please view the LICENSE * file that was distributed with this source code. */ namespace Symfony\Component\Routing;

Use `getSize()` instead. * added `RedisSessionHandler` to use Redis as a session storage * The `get()` method of the `AcceptHeader` class now takes into account the `*` and `*/*` default values (if they are present in the Accept HTTP header) when looking for items. * deprecated `Request::getSession()` when no session has been set. Use `Request::hasSession()` instead. * added `CannotWriteFileException`, `ExtensionFileException`, `FormSizeFileException`, `IniSizeFileException`, `NoFileException`, `NoTmpDirFileException`, `PartialFileException` to handle failed `UploadedFile`. * added `MigratingSessionHandler` for migrating between two session handlers without losing sessions * added `HeaderUtils`. 4.0.0 ----- * the `Request::setTrustedHeaderName()` and `Request::getTrustedHeaderName()` methods have been removed * the `Request::HEADER_CLIENT_IP` constant has been removed, use `Request::HEADER_X_FORWARDED_FOR` instead * the `Request::HEADER_CLIENT_HOST` constant has been removed, use `Request::HEADER_X_FORWARDED_HOST` instead * the `Request::HEADER_CLIENT_PROTO` constant has been removed, use `Request::HEADER_X_FORWARDED_PROTO` instead * the `Request::HEADER_CLIENT_PORT` constant has been removed, use `Request::HEADER_X_FORWARDED_PORT` instead * checking for cacheable HTTP methods using the `Request::isMethodSafe()` method (by not passing `false` as its argument) is not supported anymore and throws a `\BadMethodCallException` * the `WriteCheckSessionHandler`, `NativeSessionHandler` and `NativeProxy` classes have been removed * setting session save handlers that do not implement `\SessionHandlerInterface` in `NativeSessionStorage::setSaveHandler()` is not supported anymore and throws a `\TypeError` 3.4.0 ----- * implemented PHP 7.0's `SessionUpdateTimestampHandlerInterface` with a new `AbstractSessionHandler` base class and a new `StrictSessionHandler` wrapper * deprecated the `WriteCheckSessionHandler`, `NativeSessionHandler` and `NativeProxy` classes * deprecated setting session save handlers that do not implement `\SessionHandlerInterface` in `NativeSessionStorage::setSaveHandler()` * deprecated using `MongoDbSessionHandler` with the legacy mongo extension; use it with the mongodb/mongodb package and ext-mongodb instead * deprecated `MemcacheSessionHandler`; use `MemcachedSessionHandler` instead 3.3.0 ----- * the `Request::setTrustedProxies()` method takes a new `$trustedHeaderSet` argument, see https://symfony.com/doc/current/deployment/proxies.html for more info, * deprecated the `Request::setTrustedHeaderName()` and `Request::getTrustedHeaderName()` methods, * added `File\Stream`, to be passed to `BinaryFileResponse` when the size of the served file is unknown, disabling `Range` and `Content-Length` handling, switching to chunked encoding instead * added the `Cookie::fromString()` method that allows to create a cookie from a raw header string 3.1.0 ----- * Added support for creating `JsonResponse` with a string of JSON data 3.0.0 ----- * The precedence of parameters returned from `Request::get()` changed from "GET, PATH, BODY" to "PATH, GET, BODY" 2.8.0 ----- * Finding deep items in `ParameterBag::get()` is deprecated since version 2.8 and will be removed in 3.0. 2.6.0 ----- * PdoSessionHandler changes - implemented different session locking strategies to prevent loss of data by concurrent access to the same session - [BC BREAK] save session data in a binary column without base64_encode - [BC BREAK] added lifetime column to the session table which allows to have different lifetimes for each session - implemented lazy connections that are only opened when a session is used by either passing a dsn string explicitly or falling back to session.save_path ini setting - added a createTable method that initializes a correctly defined table depending on the database vendor 2.5.0 ----- * added `JsonResponse::setEncodingOptions()` & `JsonResponse::getEncodingOptions()` for easier manipulation of the options used while encoding data to JSON format. 2.4.0 ----- * added RequestStack * added Request::getEncodings() * added accessors methods to session handlers 2.3.0 ----- * added support for ranges of IPs in trusted proxies * `UploadedFile::isValid` now returns false if the file was not uploaded via HTTP (in a non-test mode) * Improved error-handling of `\Symfony\Component\HttpFoundation\Session\Storage\Handler\PdoSessionHandler` to ensure the supplied PDO handler throws Exceptions on error (as the class expects). Added related test cases to verify that Exceptions are properly thrown when the PDO queries fail. 2.2.0 ----- * fixed the Request::create() precedence (URI information always take precedence now) * added Request::getTrustedProxies() * deprecated Request::isProxyTrusted() * [BC BREAK] JsonResponse does not turn a top level empty array to an object anymore, use an ArrayObject to enforce objects * added a IpUtils class to check if an IP belongs to a CIDR * added Request::getRealMethod() to get the "real" HTTP method (getMethod() returns the "intended" HTTP method) * disabled _method request parameter support by default (call Request::enableHttpMethodParameterOverride() to enable it, and Request::getHttpMethodParameterOverride() to check if it is supported) * Request::splitHttpAcceptHeader() method is deprecated and will be removed in 2.3 * Deprecated Flashbag::count() and \Countable interface, will be removed in 2.3 2.1.0 ----- * added Request::getSchemeAndHttpHost() and Request::getUserInfo() * added a fluent interface to the Response class * added Request::isProxyTrusted() * added JsonResponse * added a getTargetUrl method to RedirectResponse * added support for streamed responses * made Response::prepare() method the place to enforce HTTP specification * [BC BREAK] moved management of the locale from the Session class to the Request class * added a generic access to the PHP built-in filter mechanism: ParameterBag::filter() * made FileBinaryMimeTypeGuesser command configurable * added Request::getUser() and Request::getPassword() * added support for the PATCH method in Request * removed the ContentTypeMimeTypeGuesser class as it is deprecated and never used on PHP 5.3 * added ResponseHeaderBag::makeDisposition() (implements RFC 6266) * made mimetype to extension conversion configurable * [BC BREAK] Moved all session related classes and interfaces into own namespace, as `Symfony\Component\HttpFoundation\Session` and renamed classes accordingly. Session handlers are located in the subnamespace `Symfony\Component\HttpFoundation\Session\Handler`. * SessionHandlers must implement `\SessionHandlerInterface` or extend from the `Symfony\Component\HttpFoundation\Storage\Handler\NativeSessionHandler` base class. * Added internal storage driver proxy mechanism for forward compatibility with PHP 5.4 `\SessionHandler` class. * Added session handlers for custom Memcache, Memcached and Null session save handlers. * [BC BREAK] Removed `NativeSessionStorage` and replaced with `NativeFileSessionHandler`. * [BC BREAK] `SessionStorageInterface` methods removed: `write()`, `read()` and `remove()`. Added `getBag()`, `registerBag()`. The `NativeSessionStorage` class is a mediator for the session storage internals including the session handlers which do the real work of participating in the internal PHP session workflow. * [BC BREAK] Introduced mock implementations of `SessionStorage` to enable unit and functional testing without starting real PHP sessions. Removed `ArraySessionStorage`, and replaced with `MockArraySessionStorage` for unit tests; removed `FilesystemSessionStorage`, and replaced with`MockFileSessionStorage` for functional tests. These do not interact with global session ini configuration values, session functions or `$_SESSION` superglobal. This means they can be configured directly allowing multiple instances to work without conflicting in the same PHP process. * [BC BREAK] Removed the `close()` method from the `Session` class, as this is now redundant. * Deprecated the following methods from the Session class: `setFlash()`, `setFlashes()` `getFlash()`, `hasFlash()`, and `removeFlash()`. Use `getFlashBag()` instead which returns a `FlashBagInterface`. * `Session->clear()` now only clears session attributes as before it cleared flash messages and attributes. `Session->getFlashBag()->all()` clears flashes now. * Session data is now managed by `SessionBagInterface` to better encapsulate session data. * Refactored session attribute and flash messages system to their own `SessionBagInterface` implementations. * Added `FlashBag`. Flashes expire when retrieved by `get()` or `all()`. This implementation is ESI compatible. * Added `AutoExpireFlashBag` (default) to replicate Symfony 2.0.x auto expire behavior of messages auto expiring after one page page load. Messages must be retrieved by `get()` or `all()`. * Added `Symfony\Component\HttpFoundation\Attribute\AttributeBag` to replicate attributes storage behavior from 2.0.x (default). * Added `Symfony\Component\HttpFoundation\Attribute\NamespacedAttributeBag` for namespace session attributes. * Flash API can stores messages in an array so there may be multiple messages per flash type. The old `Session` class API remains without BC break as it will allow single messages as before. * Added basic session meta-data to the session to record session create time, last updated time, and the lifetime of the session cookie that was provided to the client. * Request::getClientIp() method doesn't take a parameter anymore but bases itself on the trustProxy parameter. * Added isMethod() to Request object. * [BC BREAK] The methods `getPathInfo()`, `getBaseUrl()` and `getBasePath()` of a `Request` now all return a raw value (vs a urldecoded value before). Any call to one of these methods must be checked and wrapped in a `rawurldecode()` if needed.

PK �q�\��3� � ' symfony/deprecation-contracts/README.mdnu �Iw�� Symfony Deprecation Contracts ============================= A generic function and convention to trigger deprecation notices. This package provides a single global function named `trigger_deprecation()` that triggers silenced deprecation notices. By using a custom PHP error handler such as the one provided by the Symfony ErrorHandler component, the triggered deprecations can be caught and logged for later discovery, both on dev and prod environments. The function requires at least 3 arguments: - the name of the Composer package that is triggering the deprecation - the version of the package that introduced the deprecation - the message of the deprecation - more arguments can be provided: they will be inserted in the message using `printf()` formatting Example: ```php trigger_deprecation('symfony/blockchain', '8.9', 'Using "%s" is deprecated, use "%s" instead.', 'bitcoin', 'fabcoin'); ``` This will generate the following message: `Since symfony/blockchain 8.9: Using "bitcoin" is deprecated, use "fabcoin" instead.` While not necessarily recommended, the deprecation notices can be completely ignored by declaring an empty `function trigger_deprecation() {}` in your application.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/) and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). ## Unreleased ## 2.1.0 - 2021-10-06 ### Changed - Attempting to create a `Uri` object from a malformed URI will no longer throw a generic `InvalidArgumentException`, but rather a `MalformedUriException`, which inherits from the former for backwards compatibility.

Header values may be surrounded by whitespace which should be ignored according to RFC 7230 Section 3.2.4. This does not apply to header names. - `Uri::withAddedHeader` with an array of header values. - `Uri::resolve` when base path has no slash and handling of fragment. - Handling of encoding in `Uri::with(out)QueryValue` so one can pass the key/value both in encoded as well as decoded form to those methods. This is consistent with withPath, withQuery etc. - `ServerRequest::withoutAttribute` when attribute value is null. ## [1.3.0] - 2016-04-13 ### Added - Remaining interfaces needed for full PSR7 compatibility (ServerRequestInterface, UploadedFileInterface, etc.). - Support for stream_for from scalars. ### Changed - Can now extend Uri. ### Fixed - A bug in validating request methods by making it more permissive. ## [1.2.3] - 2016-02-18 ### Fixed - Support in `GuzzleHttp\Psr7\CachingStream` for seeking forward on remote streams, which can sometimes return fewer bytes than requested with `fread`. - Handling of gzipped responses with FNAME headers. ## [1.2.2] - 2016-01-22 ### Added - Support for URIs without any authority. - Support for HTTP 451 'Unavailable For Legal Reasons.' - Support for using '0' as a filename. - Support for including non-standard ports in Host headers. ## [1.2.1] - 2015-11-02 ### Changes - Now supporting negative offsets when seeking to SEEK_END. ## [1.2.0] - 2015-08-15 ### Changed - Body as `"0"` is now properly added to a response. - Now allowing forward seeking in CachingStream. - Now properly parsing HTTP requests that contain proxy targets in `parse_request`. - functions.php is now conditionally required. - user-info is no longer dropped when resolving URIs. ## [1.1.0] - 2015-06-24 ### Changed - URIs can now be relative. - `multipart/form-data` headers are now overridden case-insensitively. - URI paths no longer encode the following characters because they are allowed in URIs: "(", ")", "*", "!", "'" - A port is no longer added to a URI when the scheme is missing and no port is present. ## 1.0.0 - 2015-05-19 Initial release.

Above all listen to me. ``` ## BufferStream `GuzzleHttp\Psr7\BufferStream` Provides a buffer stream that can be written to fill a buffer, and read from to remove bytes from the buffer. This stream returns a "hwm" metadata value that tells upstream consumers what the configured high water mark of the stream is, or the maximum preferred size of the buffer. ```php use GuzzleHttp\Psr7; // When more than 1024 bytes are in the buffer, it will begin returning // false to writes. This is an indication that writers should slow down. $buffer = new Psr7\BufferStream(1024); ``` ## CachingStream The CachingStream is used to allow seeking over previously read bytes on non-seekable streams. This can be useful when transferring a non-seekable entity body fails due to needing to rewind the stream (for example, resulting from a redirect). Data that is read from the remote stream will be buffered in a PHP temp stream so that previously read bytes are cached first in memory, then on disk. ```php use GuzzleHttp\Psr7; $original = Psr7\Utils::streamFor(fopen('http://www.google.com', 'r')); $stream = new Psr7\CachingStream($original); $stream->read(1024); echo $stream->tell(); // 1024 $stream->seek(0); echo $stream->tell(); // 0 ``` ## DroppingStream `GuzzleHttp\Psr7\DroppingStream` Stream decorator that begins dropping data once the size of the underlying stream becomes too full. ```php use GuzzleHttp\Psr7; // Create an empty stream $stream = Psr7\Utils::streamFor(); // Start dropping data when the stream has more than 10 bytes $dropping = new Psr7\DroppingStream($stream, 10); $dropping->write('01234567890123456789'); echo $stream; // 0123456789 ``` ## FnStream `GuzzleHttp\Psr7\FnStream` Compose stream implementations based on a hash of functions. Allows for easy testing and extension of a provided stream without needing to create a concrete class for a simple extension point. ```php use GuzzleHttp\Psr7; $stream = Psr7\Utils::streamFor('hi'); $fnStream = Psr7\FnStream::decorate($stream, [ 'rewind' => function () use ($stream) { echo 'About to rewind - '; $stream->rewind(); echo 'rewound!'; } ]); $fnStream->rewind(); // Outputs: About to rewind - rewound! ``` ## InflateStream `GuzzleHttp\Psr7\InflateStream` Uses PHP's zlib.inflate filter to inflate zlib (HTTP deflate, RFC1950) or gzipped (RFC1952) content. This stream decorator converts the provided stream to a PHP stream resource, then appends the zlib.inflate filter. The stream is then converted back to a Guzzle stream resource to be used as a Guzzle stream. ## LazyOpenStream `GuzzleHttp\Psr7\LazyOpenStream` Lazily reads or writes to a file that is opened only after an IO operation take place on the stream. ```php use GuzzleHttp\Psr7; $stream = new Psr7\LazyOpenStream('/path/to/file', 'r'); // The file has not yet been opened... echo $stream->read(10); // The file is opened and read from only when needed. ``` ## LimitStream `GuzzleHttp\Psr7\LimitStream` LimitStream can be used to read a subset or slice of an existing stream object. This can be useful for breaking a large file into smaller pieces to be sent in chunks (e.g. Amazon S3's multipart upload API). ```php use GuzzleHttp\Psr7; $original = Psr7\Utils::streamFor(fopen('/tmp/test.txt', 'r+')); echo $original->getSize(); // >>> 1048576 // Limit the size of the body to 1024 bytes and start reading from byte 2048 $stream = new Psr7\LimitStream($original, 1024, 2048); echo $stream->getSize(); // >>> 1024 echo $stream->tell(); // >>> 0 ``` ## MultipartStream `GuzzleHttp\Psr7\MultipartStream` Stream that when read returns bytes for a streaming multipart or multipart/form-data stream. ## NoSeekStream `GuzzleHttp\Psr7\NoSeekStream` NoSeekStream wraps a stream and does not allow seeking. ```php use GuzzleHttp\Psr7; $original = Psr7\Utils::streamFor('foo'); $noSeek = new Psr7\NoSeekStream($original); echo $noSeek->read(3); // foo var_export($noSeek->isSeekable()); // false $noSeek->seek(0); var_export($noSeek->read(3)); // NULL ``` ## PumpStream `GuzzleHttp\Psr7\PumpStream` Provides a read only stream that pumps data from a PHP callable. When invoking the provided callable, the PumpStream will pass the amount of data requested to read to the callable. The callable can choose to ignore this value and return fewer or more bytes than requested. Any extra data returned by the provided callable is buffered internally until drained using the read() function of the PumpStream. The provided callable MUST return false when there is no more data to read. ## Implementing stream decorators Creating a stream decorator is very easy thanks to the `GuzzleHttp\Psr7\StreamDecoratorTrait`. This trait provides methods that implement `Psr\Http\Message\StreamInterface` by proxying to an underlying stream. Just `use` the `StreamDecoratorTrait` and implement your custom methods. For example, let's say we wanted to call a specific function each time the last byte is read from a stream. This could be implemented by overriding the `read()` method. ```php use Psr\Http\Message\StreamInterface; use GuzzleHttp\Psr7\StreamDecoratorTrait; class EofCallbackStream implements StreamInterface { use StreamDecoratorTrait; private $callback; public function __construct(StreamInterface $stream, callable $cb) { $this->stream = $stream; $this->callback = $cb; } public function read($length) { $result = $this->stream->read($length); // Invoke the callback when EOF is hit. if ($this->eof()) { call_user_func($this->callback); } return $result; } } ``` This decorator could be added to any existing stream and used like so: ```php use GuzzleHttp\Psr7; $original = Psr7\Utils::streamFor('foo'); $eofStream = new EofCallbackStream($original, function () { echo 'EOF!'; }); $eofStream->read(2); $eofStream->read(1); // echoes "EOF!" $eofStream->seek(0); $eofStream->read(3); // echoes "EOF!" ``` ## PHP StreamWrapper You can use the `GuzzleHttp\Psr7\StreamWrapper` class if you need to use a PSR-7 stream as a PHP stream resource. Use the `GuzzleHttp\Psr7\StreamWrapper::getResource()` method to create a PHP stream from a PSR-7 stream. ```php use GuzzleHttp\Psr7\StreamWrapper; $stream = GuzzleHttp\Psr7\Utils::streamFor('hello!'); $resource = StreamWrapper::getResource($stream); echo fread($resource, 6); // outputs hello! ``` # Static API There are various static methods available under the `GuzzleHttp\Psr7` namespace. ## `GuzzleHttp\Psr7\Message::toString` `public static function toString(MessageInterface $message): string` Returns the string representation of an HTTP message. ```php $request = new GuzzleHttp\Psr7\Request('GET', 'http://example.com'); echo GuzzleHttp\Psr7\Message::toString($request); ``` ## `GuzzleHttp\Psr7\Message::bodySummary` `public static function bodySummary(MessageInterface $message, int $truncateAt = 120): string|null` Get a short summary of the message body. Will return `null` if the response is not printable. ## `GuzzleHttp\Psr7\Message::rewindBody` `public static function rewindBody(MessageInterface $message): void` Attempts to rewind a message body and throws an exception on failure. The body of the message will only be rewound if a call to `tell()` returns a value other than `0`. ## `GuzzleHttp\Psr7\Message::parseMessage` `public static function parseMessage(string $message): array` Parses an HTTP message into an associative array. The array contains the "start-line" key containing the start line of the message, "headers" key containing an associative array of header array values, and a "body" key containing the body of the message. ## `GuzzleHttp\Psr7\Message::parseRequestUri` `public static function parseRequestUri(string $path, array $headers): string` Constructs a URI for an HTTP request message. ## `GuzzleHttp\Psr7\Message::parseRequest` `public static function parseRequest(string $message): Request` Parses a request message string into a request object. ## `GuzzleHttp\Psr7\Message::parseResponse` `public static function parseResponse(string $message): Response` Parses a response message string into a response object. ## `GuzzleHttp\Psr7\Header::parse` `public static function parse(string|array $header): array` Parse an array of header values containing ";" separated data into an array of associative arrays representing the header key value pair data of the header. When a parameter does not contain a value, but just contains a key, this function will inject a key with a '' string value. ## `GuzzleHttp\Psr7\Header::normalize` `public static function normalize(string|array $header): array` Converts an array of header values that may contain comma separated headers into an array of headers with no comma separated values. ## `GuzzleHttp\Psr7\Query::parse` `public static function parse(string $str, int|bool $urlEncoding = true): array` Parse a query string into an associative array. If multiple values are found for the same key, the value of that key value pair will become an array. This function does not parse nested PHP style arrays into an associative array (e.g., `foo[a]=1&foo[b]=2` will be parsed into `['foo[a]' => '1', 'foo[b]' => '2'])`. ## `GuzzleHttp\Psr7\Query::build` `public static function build(array $params, int|false $encoding = PHP_QUERY_RFC3986): string` Build a query string from an array of key value pairs. This function can use the return value of `parse()` to build a query string. This function does not modify the provided keys when an array is encountered (like `http_build_query()` would). ## `GuzzleHttp\Psr7\Utils::caselessRemove` `public static function caselessRemove(iterable<string> $keys, $keys, array $data): array` Remove the items given by the keys, case insensitively from the data. ## `GuzzleHttp\Psr7\Utils::copyToStream` `public static function copyToStream(StreamInterface $source, StreamInterface $dest, int $maxLen = -1): void` Copy the contents of a stream into another stream until the given number of bytes have been read. ## `GuzzleHttp\Psr7\Utils::copyToString` `public static function copyToString(StreamInterface $stream, int $maxLen = -1): string` Copy the contents of a stream into a string until the given number of bytes have been read. ## `GuzzleHttp\Psr7\Utils::hash` `public static function hash(StreamInterface $stream, string $algo, bool $rawOutput = false): string` Calculate a hash of a stream. This method reads the entire stream to calculate a rolling hash, based on PHP's `hash_init` functions. ## `GuzzleHttp\Psr7\Utils::modifyRequest` `public static function modifyRequest(RequestInterface $request, array $changes): RequestInterface` Clone and modify a request with the given changes. This method is useful for reducing the number of clones needed to mutate a message. - method: (string) Changes the HTTP method. - set_headers: (array) Sets the given headers. - remove_headers: (array) Remove the given headers. - body: (mixed) Sets the given body. - uri: (UriInterface) Set the URI. - query: (string) Set the query string value of the URI. - version: (string) Set the protocol version. ## `GuzzleHttp\Psr7\Utils::readLine` `public static function readLine(StreamInterface $stream, int $maxLength = null): string` Read a line from the stream up to the maximum allowed buffer length. ## `GuzzleHttp\Psr7\Utils::streamFor` `public static function streamFor(resource|string|null|int|float|bool|StreamInterface|callable|\Iterator $resource = '', array $options = []): StreamInterface` Create a new stream based on the input type. Options is an associative array that can contain the following keys: - metadata: Array of custom metadata. - size: Size of the stream. This method accepts the following `$resource` types: - `Psr\Http\Message\StreamInterface`: Returns the value as-is. - `string`: Creates a stream object that uses the given string as the contents. - `resource`: Creates a stream object that wraps the given PHP stream resource. - `Iterator`: If the provided value implements `Iterator`, then a read-only stream object will be created that wraps the given iterable. Each time the stream is read from, data from the iterator will fill a buffer and will be continuously called until the buffer is equal to the requested read size. Subsequent read calls will first read from the buffer and then call `next` on the underlying iterator until it is exhausted. - `object` with `__toString()`: If the object has the `__toString()` method, the object will be cast to a string and then a stream will be returned that uses the string value. - `NULL`: When `null` is passed, an empty stream object is returned. - `callable` When a callable is passed, a read-only stream object will be created that invokes the given callable. The callable is invoked with the number of suggested bytes to read. The callable can return any number of bytes, but MUST return `false` when there is no more data to return. The stream object that wraps the callable will invoke the callable until the number of requested bytes are available. Any additional bytes will be buffered and used in subsequent reads. ```php $stream = GuzzleHttp\Psr7\Utils::streamFor('foo'); $stream = GuzzleHttp\Psr7\Utils::streamFor(fopen('/path/to/file', 'r')); $generator = function ($bytes) { for ($i = 0; $i < $bytes; $i++) { yield ' '; } } $stream = GuzzleHttp\Psr7\Utils::streamFor($generator(100)); ``` ## `GuzzleHttp\Psr7\Utils::tryFopen` `public static function tryFopen(string $filename, string $mode): resource` Safely opens a PHP stream resource using a filename. When fopen fails, PHP normally raises a warning. This function adds an error handler that checks for errors and throws an exception instead. ## `GuzzleHttp\Psr7\Utils::uriFor` `public static function uriFor(string|UriInterface $uri): UriInterface` Returns a UriInterface for the given value. This function accepts a string or UriInterface and returns a UriInterface for the given value. If the value is already a UriInterface, it is returned as-is. ## `GuzzleHttp\Psr7\MimeType::fromFilename` `public static function fromFilename(string $filename): string|null` Determines the mimetype of a file by looking at its extension. ## `GuzzleHttp\Psr7\MimeType::fromExtension` `public static function fromExtension(string $extension): string|null` Maps a file extensions to a mimetype. ## Upgrading from Function API The static API was first introduced in 1.7.0, in order to mitigate problems with functions conflicting between global and local copies of the package. The function API was removed in 2.0.0. A migration table has been provided here for your convenience: | Original Function | Replacement Method | |----------------|----------------| | `str` | `Message::toString` | | `uri_for` | `Utils::uriFor` | | `stream_for` | `Utils::streamFor` | | `parse_header` | `Header::parse` | | `normalize_header` | `Header::normalize` | | `modify_request` | `Utils::modifyRequest` | | `rewind_body` | `Message::rewindBody` | | `try_fopen` | `Utils::tryFopen` | | `copy_to_string` | `Utils::copyToString` | | `copy_to_stream` | `Utils::copyToStream` | | `hash` | `Utils::hash` | | `readline` | `Utils::readLine` | | `parse_request` | `Message::parseRequest` | | `parse_response` | `Message::parseResponse` | | `parse_query` | `Query::parse` | | `build_query` | `Query::build` | | `mimetype_from_filename` | `MimeType::fromFilename` | | `mimetype_from_extension` | `MimeType::fromExtension` | | `_parse_message` | `Message::parseMessage` | | `_parse_request_uri` | `Message::parseRequestUri` | | `get_message_body_summary` | `Message::bodySummary` | | `_caseless_remove` | `Utils::caselessRemove` | # Additional URI Methods Aside from the standard `Psr\Http\Message\UriInterface` implementation in form of the `GuzzleHttp\Psr7\Uri` class, this library also provides additional functionality when working with URIs as static methods. ## URI Types An instance of `Psr\Http\Message\UriInterface` can either be an absolute URI or a relative reference. An absolute URI has a scheme. A relative reference is used to express a URI relative to another URI, the base URI. Relative references can be divided into several forms according to [RFC 3986 Section 4.2](https://tools.ietf.org/html/rfc3986#section-4.2): - network-path references, e.g. `//example.com/path` - absolute-path references, e.g. `/path` - relative-path references, e.g. `subpath` The following methods can be used to identify the type of the URI. ### `GuzzleHttp\Psr7\Uri::isAbsolute` `public static function isAbsolute(UriInterface $uri): bool` Whether the URI is absolute, i.e. it has a scheme. ### `GuzzleHttp\Psr7\Uri::isNetworkPathReference` `public static function isNetworkPathReference(UriInterface $uri): bool` Whether the URI is a network-path reference. A relative reference that begins with two slash characters is termed an network-path reference. ### `GuzzleHttp\Psr7\Uri::isAbsolutePathReference` `public static function isAbsolutePathReference(UriInterface $uri): bool` Whether the URI is a absolute-path reference. A relative reference that begins with a single slash character is termed an absolute-path reference. ### `GuzzleHttp\Psr7\Uri::isRelativePathReference` `public static function isRelativePathReference(UriInterface $uri): bool` Whether the URI is a relative-path reference. A relative reference that does not begin with a slash character is termed a relative-path reference. ### `GuzzleHttp\Psr7\Uri::isSameDocumentReference` `public static function isSameDocumentReference(UriInterface $uri, UriInterface $base = null): bool` Whether the URI is a same-document reference. A same-document reference refers to a URI that is, aside from its fragment component, identical to the base URI. When no base URI is given, only an empty URI reference (apart from its fragment) is considered a same-document reference. ## URI Components Additional methods to work with URI components. ### `GuzzleHttp\Psr7\Uri::isDefaultPort` `public static function isDefaultPort(UriInterface $uri): bool` Whether the URI has the default port of the current scheme. `Psr\Http\Message\UriInterface::getPort` may return null or the standard port. This method can be used independently of the implementation. ### `GuzzleHttp\Psr7\Uri::composeComponents` `public static function composeComponents($scheme, $authority, $path, $query, $fragment): string` Composes a URI reference string from its various components according to [RFC 3986 Section 5.3](https://tools.ietf.org/html/rfc3986#section-5.3). Usually this method does not need to be called manually but instead is used indirectly via `Psr\Http\Message\UriInterface::__toString`. ### `GuzzleHttp\Psr7\Uri::fromParts` `public static function fromParts(array $parts): UriInterface` Creates a URI from a hash of [`parse_url`](http://php.net/manual/en/function.parse-url.php) components. ### `GuzzleHttp\Psr7\Uri::withQueryValue` `public static function withQueryValue(UriInterface $uri, $key, $value): UriInterface` Creates a new URI with a specific query string value. Any existing query string values that exactly match the provided key are removed and replaced with the given key value pair. A value of null will set the query string key without a value, e.g. "key" instead of "key=value". ### `GuzzleHttp\Psr7\Uri::withQueryValues` `public static function withQueryValues(UriInterface $uri, array $keyValueArray): UriInterface` Creates a new URI with multiple query string values. It has the same behavior as `withQueryValue()` but for an associative array of key => value. ### `GuzzleHttp\Psr7\Uri::withoutQueryValue` `public static function withoutQueryValue(UriInterface $uri, $key): UriInterface` Creates a new URI with a specific query string value removed. Any existing query string values that exactly match the provided key are removed. ## Reference Resolution `GuzzleHttp\Psr7\UriResolver` provides methods to resolve a URI reference in the context of a base URI according to [RFC 3986 Section 5](https://tools.ietf.org/html/rfc3986#section-5). This is for example also what web browsers do when resolving a link in a website based on the current request URI. ### `GuzzleHttp\Psr7\UriResolver::resolve` `public static function resolve(UriInterface $base, UriInterface $rel): UriInterface` Converts the relative URI into a new URI that is resolved against the base URI. ### `GuzzleHttp\Psr7\UriResolver::removeDotSegments` `public static function removeDotSegments(string $path): string` Removes dot segments from a path and returns the new path according to [RFC 3986 Section 5.2.4](https://tools.ietf.org/html/rfc3986#section-5.2.4). ### `GuzzleHttp\Psr7\UriResolver::relativize` `public static function relativize(UriInterface $base, UriInterface $target): UriInterface` Returns the target URI as a relative reference from the base URI. This method is the counterpart to resolve(): ```php (string) $target === (string) UriResolver::resolve($base, UriResolver::relativize($base, $target)) ``` One use-case is to use the current request URI as base URI and then generate relative links in your documents to reduce the document size or offer self-contained downloadable document archives. ```php $base = new Uri('http://example.com/a/b/'); echo UriResolver::relativize($base, new Uri('http://example.com/a/b/c')); // prints 'c'. echo UriResolver::relativize($base, new Uri('http://example.com/a/x/y')); // prints '../x/y'. echo UriResolver::relativize($base, new Uri('http://example.com/a/b/?q')); // prints '?q'. echo UriResolver::relativize($base, new Uri('http://example.org/a/b/')); // prints '//example.org/a/b/'. ``` ## Normalization and Comparison `GuzzleHttp\Psr7\UriNormalizer` provides methods to normalize and compare URIs according to [RFC 3986 Section 6](https://tools.ietf.org/html/rfc3986#section-6). ### `GuzzleHttp\Psr7\UriNormalizer::normalize` `public static function normalize(UriInterface $uri, $flags = self::PRESERVING_NORMALIZATIONS): UriInterface` Returns a normalized URI. The scheme and host component are already normalized to lowercase per PSR-7 UriInterface. This methods adds additional normalizations that can be configured with the `$flags` parameter which is a bitmask of normalizations to apply. The following normalizations are available: - `UriNormalizer::PRESERVING_NORMALIZATIONS` Default normalizations which only include the ones that preserve semantics. - `UriNormalizer::CAPITALIZE_PERCENT_ENCODING` All letters within a percent-encoding triplet (e.g., "%3A") are case-insensitive, and should be capitalized. Example: `http://example.org/a%c2%b1b` → `http://example.org/a%C2%B1b` - `UriNormalizer::DECODE_UNRESERVED_CHARACTERS` Decodes percent-encoded octets of unreserved characters. For consistency, percent-encoded octets in the ranges of ALPHA (%41–%5A and %61–%7A), DIGIT (%30–%39), hyphen (%2D), period (%2E), underscore (%5F), or tilde (%7E) should not be created by URI producers and, when found in a URI, should be decoded to their corresponding unreserved characters by URI normalizers. Example: `http://example.org/%7Eusern%61me/` → `http://example.org/~username/` - `UriNormalizer::CONVERT_EMPTY_PATH` Converts the empty path to "/" for http and https URIs. Example: `http://example.org` → `http://example.org/` - `UriNormalizer::REMOVE_DEFAULT_HOST` Removes the default host of the given URI scheme from the URI. Only the "file" scheme defines the default host "localhost". All of `file:/myfile`, `file:///myfile`, and `file://localhost/myfile` are equivalent according to RFC 3986. Example: `file://localhost/myfile` → `file:///myfile` - `UriNormalizer::REMOVE_DEFAULT_PORT` Removes the default port of the given URI scheme from the URI. Example: `http://example.org:80/` → `http://example.org/` - `UriNormalizer::REMOVE_DOT_SEGMENTS` Removes unnecessary dot-segments. Dot-segments in relative-path references are not removed as it would change the semantics of the URI reference. Example: `http://example.org/../a/b/../c/./d.html` → `http://example.org/a/c/d.html` - `UriNormalizer::REMOVE_DUPLICATE_SLASHES` Paths which include two or more adjacent slashes are converted to one. Webservers usually ignore duplicate slashes and treat those URIs equivalent. But in theory those URIs do not need to be equivalent. So this normalization may change the semantics. Encoded slashes (%2F) are not removed. Example: `http://example.org//foo///bar.html` → `http://example.org/foo/bar.html` - `UriNormalizer::SORT_QUERY_PARAMETERS` Sort query parameters with their values in alphabetical order. However, the order of parameters in a URI may be significant (this is not defined by the standard). So this normalization is not safe and may change the semantics of the URI. Example: `?lang=en&article=fred` → `?article=fred&lang=en` ### `GuzzleHttp\Psr7\UriNormalizer::isEquivalent` `public static function isEquivalent(UriInterface $uri1, UriInterface $uri2, $normalizations = self::PRESERVING_NORMALIZATIONS): bool` Whether two URIs can be considered equivalent. Both URIs are normalized automatically before comparison with the given `$normalizations` bitmask. The method also accepts relative URI references and returns true when they are equivalent. This of course assumes they will be resolved against the same base URI. If this is not the case, determination of equivalence or difference of relative references does not mean anything. ## Security If you discover a security vulnerability within this package, please send an email to security@tidelift.com.

(#226 by @WyriHaximus, #229, #231 and #232 by @clue) The `Loop` class exists as a convenient global accessor for the event loop. It provides all methods that exist on the `LoopInterface` as static methods and will automatically execute the loop at the end of the program: ```php $timer = Loop::addPeriodicTimer(0.1, function () { echo 'Tick' . PHP_EOL; }); Loop::addTimer(1.0, function () use ($timer) { Loop::cancelTimer($timer); echo 'Done' . PHP_EOL; }); ``` The explicit loop instructions are still valid and may still be useful in some applications, especially for a transition period towards the more concise style. The `Loop::get()` method can be used to get the currently active event loop instance. ```php // deprecated $loop = React\EventLoop\Factory::create(); // new $loop = React\EventLoop\Loop::get(); ``` * Minor documentation improvements and mark legacy extensions as deprecated. (#234 by @SimonFrings, #214 by @WyriHaximus and #233 and #235 by @nhedger) * Improve test suite, use GitHub actions for continuous integration (CI), update PHPUnit config and run tests on PHP 8. (#212 and #215 by @SimonFrings and #230 by @clue) ## 1.1.1 (2020-01-01) * Fix: Fix reporting connection refused errors with `ExtUvLoop` on Linux and `StreamSelectLoop` on Windows. (#207 and #208 by @clue) * Fix: Fix unsupported EventConfig and `SEGFAULT` on shutdown with `ExtEventLoop` on Windows. (#205 by @clue) * Fix: Prevent interval overflow for timers very far in the future with `ExtUvLoop`. (#196 by @PabloKowalczyk) * Fix: Check PCNTL functions for signal support instead of PCNTL extension with `StreamSelectLoop`. (#195 by @clue) * Add `.gitattributes` to exclude dev files from exports. (#201 by @reedy) * Improve test suite to fix testing `ExtUvLoop` on Travis, fix Travis CI builds, do not install `libuv` on legacy PHP setups, fix failing test cases due to inaccurate timers, run tests on Windows via Travis CI and run tests on PHP 7.4 and simplify test matrix and test setup. (#197 by @WyriHaximus and #202, #203, #204 and #209 by @clue) ## 1.1.0 (2019-02-07) * New UV based event loop (ext-uv). (#112 by @WyriHaximus) * Use high resolution timer on PHP 7.3+. (#182 by @clue) * Improve PCNTL signals by using async signal dispatching if available. (#179 by @CharlotteDunois) * Improve test suite and test suite set up. (#174 by @WyriHaximus, #181 by @clue) * Fix PCNTL signals edge case. (#183 by @clue) ## 1.0.0 (2018-07-11) * First stable LTS release, now following [SemVer](https://semver.org/). We'd like to emphasize that this component is production ready and battle-tested. We plan to support all long-term support (LTS) releases for at least 24 months, so you have a rock-solid foundation to build on top of. > Contains no other changes, so it's actually fully compatible with the v0.5.3 release. ## 0.5.3 (2018-07-09) * Improve performance by importing global functions. (#167 by @Ocramius) * Improve test suite by simplifying test bootstrap by using dev autoloader. (#169 by @lcobucci) * Minor internal changes to improved backward compatibility with PHP 5.3. (#166 by @Donatello-za) ## 0.5.2 (2018-04-24) * Feature: Improve memory consumption and runtime performance for `StreamSelectLoop` timers. (#164 by @clue) * Improve test suite by removing I/O dependency at `StreamSelectLoopTest` to fix Mac OS X tests. (#161 by @nawarian) ## 0.5.1 (2018-04-09) * Feature: New `ExtEvLoop` (PECL ext-ev) (#148 by @kaduev13) ## 0.5.0 (2018-04-05) A major feature release with a significant documentation overhaul and long overdue API cleanup! This update involves a number of BC breaks due to dropped support for deprecated functionality. We've tried hard to avoid BC breaks where possible and minimize impact otherwise. We expect that most consumers of this package will actually not be affected by any BC breaks, see below for more details. We realize that the changes listed below may seem overwhelming, but we've tried to be very clear about any possible BC breaks. Don't worry: In fact, all ReactPHP components are already compatible and support both this new release as well as providing backwards compatibility with the last release. * Feature / BC break: Add support for signal handling via new `LoopInterface::addSignal()` and `LoopInterface::removeSignal()` methods. (#104 by @WyriHaximus and #111 and #150 by @clue) ```php $loop->addSignal(SIGINT, function () { echo 'CTRL-C'; }); ``` * Feature: Significant documentation updates for `LoopInterface` and `Factory`. (#100, #119, #126, #127, #159 and #160 by @clue, #113 by @WyriHaximus and #81 and #91 by @jsor) * Feature: Add examples to ease getting started (#99, #100 and #125 by @clue, #59 by @WyriHaximus and #143 by @jsor) * Feature: Documentation for advanced timer concepts, such as monotonic time source vs wall-clock time and high precision timers with millisecond accuracy or below. (#130 and #157 by @clue) * Feature: Documentation for advanced stream concepts, such as edge-triggered event listeners and stream buffers and allow throwing Exception if stream resource is not supported. (#129 and #158 by @clue) * Feature: Throw `BadMethodCallException` on manual loop creation when required extension isn't installed. (#153 by @WyriHaximus) * Feature / BC break: First class support for legacy PHP 5.3 through PHP 7.2 and HHVM and remove all `callable` type hints for consistency reasons. (#141 and #151 by @clue) * BC break: Documentation for timer API and clean up unneeded timer API. (#102 by @clue) Remove `TimerInterface::cancel()`, use `LoopInterface::cancelTimer()` instead: ```php // old (method invoked on timer instance) $timer->cancel(); // already supported before: invoke method on loop instance $loop->cancelTimer($timer); ``` Remove unneeded `TimerInterface::setData()` and `TimerInterface::getData()`, use closure binding to add arbitrary data to timer instead: ```php // old (limited setData() and getData() only allows single variable) $name = 'Tester'; $timer = $loop->addTimer(1.0, function ($timer) { echo 'Hello ' . $timer->getData() . PHP_EOL; }); $timer->setData($name); // already supported before: closure binding allows any number of variables $name = 'Tester'; $loop->addTimer(1.0, function () use ($name) { echo 'Hello ' . $name . PHP_EOL; }); ``` Remove unneeded `TimerInterface::getLoop()`, use closure binding instead: ```php // old (getLoop() called on timer instance) $loop->addTimer(0.1, function ($timer) { $timer->getLoop()->stop(); }); // already supported before: use closure binding as usual $loop->addTimer(0.1, function () use ($loop) { $loop->stop(); }); ``` * BC break: Remove unneeded `LoopInterface::isTimerActive()` and `TimerInterface::isActive()` to reduce API surface. (#133 by @clue) ```php // old (method on timer instance or on loop instance) $timer->isActive(); $loop->isTimerActive($timer); ``` * BC break: Move `TimerInterface` one level up to `React\EventLoop\TimerInterface`. (#138 by @WyriHaximus) ```php // old (notice obsolete "Timer" namespace) assert($timer instanceof React\EventLoop\Timer\TimerInterface); // new assert($timer instanceof React\EventLoop\TimerInterface); ``` * BC break: Remove unneeded `LoopInterface::nextTick()` (and internal `NextTickQueue`), use `LoopInterface::futureTick()` instead. (#30 by @clue) ```php // old (removed) $loop->nextTick(function () { echo 'tick'; }); // already supported before $loop->futureTick(function () { echo 'tick'; }); ``` * BC break: Remove unneeded `$loop` argument for `LoopInterface::futureTick()` (and fix internal cyclic dependency). (#103 by @clue) ```php // old ($loop gets passed by default) $loop->futureTick(function ($loop) { $loop->stop(); }); // already supported before: use closure binding as usual $loop->futureTick(function () use ($loop) { $loop->stop(); }); ``` * BC break: Remove unneeded `LoopInterface::tick()`. (#72 by @jsor) ```php // old (removed) $loop->tick(); // suggested work around for testing purposes only $loop->futureTick(function () use ($loop) { $loop->stop(); }); ``` * BC break: Documentation for advanced stream API and clean up unneeded stream API. (#110 by @clue) Remove unneeded `$loop` argument for `LoopInterface::addReadStream()` and `LoopInterface::addWriteStream()`, use closure binding instead: ```php // old ($loop gets passed by default) $loop->addReadStream($stream, function ($stream, $loop) { $loop->removeReadStream($stream); }); // already supported before: use closure binding as usual $loop->addReadStream($stream, function ($stream) use ($loop) { $loop->removeReadStream($stream); }); ``` * BC break: Remove unneeded `LoopInterface::removeStream()` method, use `LoopInterface::removeReadStream()` and `LoopInterface::removeWriteStream()` instead. (#118 by @clue) ```php // old $loop->removeStream($stream); // already supported before $loop->removeReadStream($stream); $loop->removeWriteStream($stream); ``` * BC break: Rename `LibEventLoop` to `ExtLibeventLoop` and `LibEvLoop` to `ExtLibevLoop` for consistent naming for event loop implementations. (#128 by @clue) * BC break: Remove optional `EventBaseConfig` argument from `ExtEventLoop` and make its `FEATURE_FDS` enabled by default.

In order for async based libraries to be interoperable, they need to use the same event loop. This component provides a common `LoopInterface` that any library can target. This allows them to be used in the same loop, with one single [`run()`](#run) call that is controlled by the user. **Table of Contents** * [Quickstart example](#quickstart-example) * [Usage](#usage) * [Loop](#loop) * [Loop methods](#loop-methods) * [Loop autorun](#loop-autorun) * [get()](#get) * [~~Factory~~](#factory) * [~~create()~~](#create) * [Loop implementations](#loop-implementations) * [StreamSelectLoop](#streamselectloop) * [ExtEventLoop](#exteventloop) * [ExtEvLoop](#extevloop) * [ExtUvLoop](#extuvloop) * [~~ExtLibeventLoop~~](#extlibeventloop) * [~~ExtLibevLoop~~](#extlibevloop) * [LoopInterface](#loopinterface) * [run()](#run) * [stop()](#stop) * [addTimer()](#addtimer) * [addPeriodicTimer()](#addperiodictimer) * [cancelTimer()](#canceltimer) * [futureTick()](#futuretick) * [addSignal()](#addsignal) * [removeSignal()](#removesignal) * [addReadStream()](#addreadstream) * [addWriteStream()](#addwritestream) * [removeReadStream()](#removereadstream) * [removeWriteStream()](#removewritestream) * [Install](#install) * [Tests](#tests) * [License](#license) * [More](#more) ## Quickstart example Here is an async HTTP server built with just the event loop. ```php <?php use React\EventLoop\Loop; require __DIR__ . '/vendor/autoload.php'; $server = stream_socket_server('tcp://127.0.0.1:8080'); stream_set_blocking($server, false); Loop::addReadStream($server, function ($server) { $conn = stream_socket_accept($server); $data = "HTTP/1.1 200 OK\r\nContent-Length: 3\r\n\r\nHi\n"; Loop::addWriteStream($conn, function ($conn) use (&$data) { $written = fwrite($conn, $data); if ($written === strlen($data)) { fclose($conn); Loop::removeWriteStream($conn); } else { $data = substr($data, $written); } }); }); Loop::addPeriodicTimer(5, function () { $memory = memory_get_usage() / 1024; $formatted = number_format($memory, 3).'K'; echo "Current memory usage: {$formatted}\n"; }); ``` See also the [examples](examples). ## Usage As of `v1.2.0`, typical applications would use the [`Loop` object](#loop) to use the currently active event loop like this: ```php use React\EventLoop\Loop; $timer = Loop::addPeriodicTimer(0.1, function () { echo 'Tick' . PHP_EOL; }); Loop::addTimer(1.0, function () use ($timer) { Loop::cancelTimer($timer); echo 'Done' . PHP_EOL; }); ``` As an alternative, you can also explicitly create an event loop instance at the beginning, reuse it throughout your program and finally run it at the end of the program like this: ```php $loop = React\EventLoop\Loop::get(); // or deprecated React\EventLoop\Factory::create(); $timer = $loop->addPeriodicTimer(0.1, function () { echo 'Tick' . PHP_EOL; }); $loop->addTimer(1.0, function () use ($loop, $timer) { $loop->cancelTimer($timer); echo 'Done' . PHP_EOL; }); $loop->run(); ``` While the former is more concise, the latter is more explicit. In both cases, the program would perform the exact same steps. 1. The event loop instance is created at the beginning of the program. This is implicitly done the first time you call the [`Loop` class](#loop) or explicitly when using the deprecated [`Factory::create() method`](#create) (or manually instantiating any of the [loop implementations](#loop-implementations)). 2. The event loop is used directly or passed as an instance to library and application code. In this example, a periodic timer is registered with the event loop which simply outputs `Tick` every fraction of a second until another timer stops the periodic timer after a second. 3. The event loop is run at the end of the program. This is automatically done when using [`Loop` class](#loop) or explicitly with a single [`run()`](#run) call at the end of the program. As of `v1.2.0`, we highly recommend using the [`Loop` class](#loop). The explicit loop instructions are still valid and may still be useful in some applications, especially for a transition period towards the more concise style. ### Loop The `Loop` class exists as a convenient global accessor for the event loop. #### Loop methods The `Loop` class provides all methods that exist on the [`LoopInterface`](#loopinterface) as static methods: * [run()](#run) * [stop()](#stop) * [addTimer()](#addtimer) * [addPeriodicTimer()](#addperiodictimer) * [cancelTimer()](#canceltimer) * [futureTick()](#futuretick) * [addSignal()](#addsignal) * [removeSignal()](#removesignal) * [addReadStream()](#addreadstream) * [addWriteStream()](#addwritestream) * [removeReadStream()](#removereadstream) * [removeWriteStream()](#removewritestream) If you're working with the event loop in your application code, it's often easiest to directly interface with the static methods defined on the `Loop` class like this: ```php use React\EventLoop\Loop; $timer = Loop::addPeriodicTimer(0.1, function () { echo 'Tick' . PHP_EOL; }); Loop::addTimer(1.0, function () use ($timer) { Loop::cancelTimer($timer); echo 'Done' . PHP_EOL; }); ``` On the other hand, if you're familiar with object-oriented programming (OOP) and dependency injection (DI), you may want to inject an event loop instance and invoke instance methods on the `LoopInterface` like this: ```php use React\EventLoop\Loop; use React\EventLoop\LoopInterface; class Greeter { private $loop; public function __construct(LoopInterface $loop) { $this->loop = $loop; } public function greet(string $name) { $this->loop->addTimer(1.0, function () use ($name) { echo 'Hello ' . $name . '!' . PHP_EOL; }); } } $greeter = new Greeter(Loop::get()); $greeter->greet('Alice'); $greeter->greet('Bob'); ``` Each static method call will be forwarded as-is to the underlying event loop instance by using the [`Loop::get()`](#get) call internally. See [`LoopInterface`](#loopinterface) for more details about available methods. #### Loop autorun When using the `Loop` class, it will automatically execute the loop at the end of the program. This means the following example will schedule a timer and will automatically execute the program until the timer event fires: ```php use React\EventLoop\Loop; Loop::addTimer(1.0, function () { echo 'Hello' . PHP_EOL; }); ``` As of `v1.2.0`, we highly recommend using the `Loop` class this way and omitting any explicit [`run()`](#run) calls. For BC reasons, the explicit [`run()`](#run) method is still valid and may still be useful in some applications, especially for a transition period towards the more concise style. If you don't want the `Loop` to run automatically, you can either explicitly [`run()`](#run) or [`stop()`](#stop) it. This can be useful if you're using a global exception handler like this: ```php use React\EventLoop\Loop; Loop::addTimer(10.0, function () { echo 'Never happens'; }); set_exception_handler(function (Throwable $e) { echo 'Error: ' . $e->getMessage() . PHP_EOL; Loop::stop(); }); throw new RuntimeException('Demo'); ``` #### get() The `get(): LoopInterface` method can be used to get the currently active event loop instance. This method will always return the same event loop instance throughout the lifetime of your application. ```php use React\EventLoop\Loop; use React\EventLoop\LoopInterface; $loop = Loop::get(); assert($loop instanceof LoopInterface); assert($loop === Loop::get()); ``` This is particularly useful if you're using object-oriented programming (OOP) and dependency injection (DI). In this case, you may want to inject an event loop instance and invoke instance methods on the `LoopInterface` like this: ```php use React\EventLoop\Loop; use React\EventLoop\LoopInterface; class Greeter { private $loop; public function __construct(LoopInterface $loop) { $this->loop = $loop; } public function greet(string $name) { $this->loop->addTimer(1.0, function () use ($name) { echo 'Hello ' . $name . '!' . PHP_EOL; }); } } $greeter = new Greeter(Loop::get()); $greeter->greet('Alice'); $greeter->greet('Bob'); ``` See [`LoopInterface`](#loopinterface) for more details about available methods. ### ~~Factory~~ > Deprecated since v1.2.0, see [`Loop` class](#loop) instead. The deprecated `Factory` class exists as a convenient way to pick the best available [event loop implementation](#loop-implementations). #### ~~create()~~ > Deprecated since v1.2.0, see [`Loop::get()`](#get) instead. The deprecated `create(): LoopInterface` method can be used to create a new event loop instance: ```php // deprecated $loop = React\EventLoop\Factory::create(); // new $loop = React\EventLoop\Loop::get(); ``` This method always returns an instance implementing [`LoopInterface`](#loopinterface), the actual [event loop implementation](#loop-implementations) is an implementation detail. This method should usually only be called once at the beginning of the program. ### Loop implementations In addition to the [`LoopInterface`](#loopinterface), there are a number of event loop implementations provided. All of the event loops support these features: * File descriptor polling * One-off timers * Periodic timers * Deferred execution on future loop tick For most consumers of this package, the underlying event loop implementation is an implementation detail. You should use the [`Factory`](#factory) to automatically create a new instance. Advanced! If you explicitly need a certain event loop implementation, you can manually instantiate one of the following classes. Note that you may have to install the required PHP extensions for the respective event loop implementation first or they will throw a `BadMethodCallException` on creation. #### StreamSelectLoop A `stream_select()` based event loop. This uses the [`stream_select()`](https://www.php.net/manual/en/function.stream-select.php) function and is the only implementation which works out of the box with PHP. This event loop works out of the box on PHP 5.3 through PHP 7+ and HHVM. This means that no installation is required and this library works on all platforms and supported PHP versions. Accordingly, the [`Factory`](#factory) will use this event loop by default if you do not install any of the event loop extensions listed below. Under the hood, it does a simple `select` system call. This system call is limited to the maximum file descriptor number of `FD_SETSIZE` (platform dependent, commonly 1024) and scales with `O(m)` (`m` being the maximum file descriptor number passed). This means that you may run into issues when handling thousands of streams concurrently and you may want to look into using one of the alternative event loop implementations listed below in this case. If your use case is among the many common use cases that involve handling only dozens or a few hundred streams at once, then this event loop implementation performs really well. If you want to use signal handling (see also [`addSignal()`](#addsignal) below), this event loop implementation requires `ext-pcntl`. This extension is only available for Unix-like platforms and does not support Windows. It is commonly installed as part of many PHP distributions. If this extension is missing (or you're running on Windows), signal handling is not supported and throws a `BadMethodCallException` instead. This event loop is known to rely on wall-clock time to schedule future timers when using any version before PHP 7.3, because a monotonic time source is only available as of PHP 7.3 (`hrtime()`). While this does not affect many common use cases, this is an important distinction for programs that rely on a high time precision or on systems that are subject to discontinuous time adjustments (time jumps). This means that if you schedule a timer to trigger in 30s on PHP < 7.3 and then adjust your system time forward by 20s, the timer may trigger in 10s. See also [`addTimer()`](#addtimer) for more details. #### ExtEventLoop An `ext-event` based event loop. This uses the [`event` PECL extension](https://pecl.php.net/package/event), that provides an interface to `libevent` library. `libevent` itself supports a number of system-specific backends (epoll, kqueue). This loop is known to work with PHP 5.4 through PHP 7+. #### ExtEvLoop An `ext-ev` based event loop. This loop uses the [`ev` PECL extension](https://pecl.php.net/package/ev), that provides an interface to `libev` library. `libev` itself supports a number of system-specific backends (epoll, kqueue). This loop is known to work with PHP 5.4 through PHP 7+. #### ExtUvLoop An `ext-uv` based event loop. This loop uses the [`uv` PECL extension](https://pecl.php.net/package/uv), that provides an interface to `libuv` library. `libuv` itself supports a number of system-specific backends (epoll, kqueue). This loop is known to work with PHP 7+. #### ~~ExtLibeventLoop~~ > Deprecated since v1.2.0, use [`ExtEventLoop`](#exteventloop) instead. An `ext-libevent` based event loop. This uses the [`libevent` PECL extension](https://pecl.php.net/package/libevent), that provides an interface to `libevent` library. `libevent` itself supports a number of system-specific backends (epoll, kqueue). This event loop does only work with PHP 5. An [unofficial update](https://github.com/php/pecl-event-libevent/pull/2) for PHP 7 does exist, but it is known to cause regular crashes due to `SEGFAULT`s. To reiterate: Using this event loop on PHP 7 is not recommended. Accordingly, the [`Factory`](#factory) will not try to use this event loop on PHP 7. This event loop is known to trigger a readable listener only if the stream *becomes* readable (edge-triggered) and may not trigger if the stream has already been readable from the beginning. This also implies that a stream may not be recognized as readable when data is still left in PHP's internal stream buffers. As such, it's recommended to use `stream_set_read_buffer($stream, 0);` to disable PHP's internal read buffer in this case. See also [`addReadStream()`](#addreadstream) for more details. #### ~~ExtLibevLoop~~ > Deprecated since v1.2.0, use [`ExtEvLoop`](#extevloop) instead. An `ext-libev` based event loop. This uses an [unofficial `libev` extension](https://github.com/m4rw3r/php-libev), that provides an interface to `libev` library. `libev` itself supports a number of system-specific backends (epoll, kqueue). This loop does only work with PHP 5. An update for PHP 7 is [unlikely](https://github.com/m4rw3r/php-libev/issues/8) to happen any time soon. ### LoopInterface #### run() The `run(): void` method can be used to run the event loop until there are no more tasks to perform. For many applications, this method is the only directly visible invocation on the event loop. As a rule of thumb, it is usally recommended to attach everything to the same loop instance and then run the loop once at the bottom end of the application. ```php $loop->run(); ``` This method will keep the loop running until there are no more tasks to perform. In other words: This method will block until the last timer, stream and/or signal has been removed. Likewise, it is imperative to ensure the application actually invokes this method once. Adding listeners to the loop and missing to actually run it will result in the application exiting without actually waiting for any of the attached listeners. This method MUST NOT be called while the loop is already running. This method MAY be called more than once after it has explicity been [`stop()`ped](#stop) or after it automatically stopped because it previously did no longer have anything to do. #### stop() The `stop(): void` method can be used to instruct a running event loop to stop. This method is considered advanced usage and should be used with care. As a rule of thumb, it is usually recommended to let the loop stop only automatically when it no longer has anything to do. This method can be used to explicitly instruct the event loop to stop: ```php $loop->addTimer(3.0, function () use ($loop) { $loop->stop(); }); ``` Calling this method on a loop instance that is not currently running or on a loop instance that has already been stopped has no effect. #### addTimer() The `addTimer(float $interval, callable $callback): TimerInterface` method can be used to enqueue a callback to be invoked once after the given interval. The timer callback function MUST be able to accept a single parameter, the timer instance as also returned by this method or you MAY use a function which has no parameters at all. The timer callback function MUST NOT throw an `Exception`. The return value of the timer callback function will be ignored and has no effect, so for performance reasons you're recommended to not return any excessive data structures. Unlike [`addPeriodicTimer()`](#addperiodictimer), this method will ensure the callback will be invoked only once after the given interval. You can invoke [`cancelTimer`](#canceltimer) to cancel a pending timer. ```php $loop->addTimer(0.8, function () { echo 'world!' . PHP_EOL; }); $loop->addTimer(0.3, function () { echo 'hello '; }); ``` See also [example #1](examples). If you want to access any variables within your callback function, you can bind arbitrary data to a callback closure like this: ```php function hello($name, LoopInterface $loop) { $loop->addTimer(1.0, function () use ($name) { echo "hello $name\n"; }); } hello('Tester', $loop); ``` This interface does not enforce any particular timer resolution, so special care may have to be taken if you rely on very high precision with millisecond accuracy or below. Event loop implementations SHOULD work on a best effort basis and SHOULD provide at least millisecond accuracy unless otherwise noted. Many existing event loop implementations are known to provide microsecond accuracy, but it's generally not recommended to rely on this high precision. Similarly, the execution order of timers scheduled to execute at the same time (within its possible accuracy) is not guaranteed. This interface suggests that event loop implementations SHOULD use a monotonic time source if available. Given that a monotonic time source is only available as of PHP 7.3 by default, event loop implementations MAY fall back to using wall-clock time. While this does not affect many common use cases, this is an important distinction for programs that rely on a high time precision or on systems that are subject to discontinuous time adjustments (time jumps). This means that if you schedule a timer to trigger in 30s and then adjust your system time forward by 20s, the timer SHOULD still trigger in 30s. See also [event loop implementations](#loop-implementations) for more details. #### addPeriodicTimer() The `addPeriodicTimer(float $interval, callable $callback): TimerInterface` method can be used to enqueue a callback to be invoked repeatedly after the given interval. The timer callback function MUST be able to accept a single parameter, the timer instance as also returned by this method or you MAY use a function which has no parameters at all. The timer callback function MUST NOT throw an `Exception`. The return value of the timer callback function will be ignored and has no effect, so for performance reasons you're recommended to not return any excessive data structures. Unlike [`addTimer()`](#addtimer), this method will ensure the the callback will be invoked infinitely after the given interval or until you invoke [`cancelTimer`](#canceltimer). ```php $timer = $loop->addPeriodicTimer(0.1, function () { echo 'tick!' . PHP_EOL; }); $loop->addTimer(1.0, function () use ($loop, $timer) { $loop->cancelTimer($timer); echo 'Done' . PHP_EOL; }); ``` See also [example #2](examples). If you want to limit the number of executions, you can bind arbitrary data to a callback closure like this: ```php function hello($name, LoopInterface $loop) { $n = 3; $loop->addPeriodicTimer(1.0, function ($timer) use ($name, $loop, &$n) { if ($n > 0) { --$n; echo "hello $name\n"; } else { $loop->cancelTimer($timer); } }); } hello('Tester', $loop); ``` This interface does not enforce any particular timer resolution, so special care may have to be taken if you rely on very high precision with millisecond accuracy or below. Event loop implementations SHOULD work on a best effort basis and SHOULD provide at least millisecond accuracy unless otherwise noted. Many existing event loop implementations are known to provide microsecond accuracy, but it's generally not recommended to rely on this high precision. Similarly, the execution order of timers scheduled to execute at the same time (within its possible accuracy) is not guaranteed. This interface suggests that event loop implementations SHOULD use a monotonic time source if available. Given that a monotonic time source is only available as of PHP 7.3 by default, event loop implementations MAY fall back to using wall-clock time. While this does not affect many common use cases, this is an important distinction for programs that rely on a high time precision or on systems that are subject to discontinuous time adjustments (time jumps). This means that if you schedule a timer to trigger in 30s and then adjust your system time forward by 20s, the timer SHOULD still trigger in 30s. See also [event loop implementations](#loop-implementations) for more details. Additionally, periodic timers may be subject to timer drift due to re-scheduling after each invocation. As such, it's generally not recommended to rely on this for high precision intervals with millisecond accuracy or below. #### cancelTimer() The `cancelTimer(TimerInterface $timer): void` method can be used to cancel a pending timer. See also [`addPeriodicTimer()`](#addperiodictimer) and [example #2](examples). Calling this method on a timer instance that has not been added to this loop instance or on a timer that has already been cancelled has no effect. #### futureTick() The `futureTick(callable $listener): void` method can be used to schedule a callback to be invoked on a future tick of the event loop. This works very much similar to timers with an interval of zero seconds, but does not require the overhead of scheduling a timer queue. The tick callback function MUST be able to accept zero parameters. The tick callback function MUST NOT throw an `Exception`. The return value of the tick callback function will be ignored and has no effect, so for performance reasons you're recommended to not return any excessive data structures. If you want to access any variables within your callback function, you can bind arbitrary data to a callback closure like this: ```php function hello($name, LoopInterface $loop) { $loop->futureTick(function () use ($name) { echo "hello $name\n"; }); } hello('Tester', $loop); ``` Unlike timers, tick callbacks are guaranteed to be executed in the order they are enqueued. Also, once a callback is enqueued, there's no way to cancel this operation. This is often used to break down bigger tasks into smaller steps (a form of cooperative multitasking). ```php $loop->futureTick(function () { echo 'b'; }); $loop->futureTick(function () { echo 'c'; }); echo 'a'; ``` See also [example #3](examples). #### addSignal() The `addSignal(int $signal, callable $listener): void` method can be used to register a listener to be notified when a signal has been caught by this process. This is useful to catch user interrupt signals or shutdown signals from tools like `supervisor` or `systemd`. The listener callback function MUST be able to accept a single parameter, the signal added by this method or you MAY use a function which has no parameters at all. The listener callback function MUST NOT throw an `Exception`. The return value of the listener callback function will be ignored and has no effect, so for performance reasons you're recommended to not return any excessive data structures. ```php $loop->addSignal(SIGINT, function (int $signal) { echo 'Caught user interrupt signal' . PHP_EOL; }); ``` See also [example #4](examples). Signaling is only available on Unix-like platform, Windows isn't supported due to operating system limitations. This method may throw a `BadMethodCallException` if signals aren't supported on this platform, for example when required extensions are missing. **Note: A listener can only be added once to the same signal, any attempts to add it more then once will be ignored.** #### removeSignal() The `removeSignal(int $signal, callable $listener): void` method can be used to remove a previously added signal listener. ```php $loop->removeSignal(SIGINT, $listener); ``` Any attempts to remove listeners that aren't registered will be ignored. #### addReadStream() > Advanced! Note that this low-level API is considered advanced usage. Most use cases should probably use the higher-level [readable Stream API](https://github.com/reactphp/stream#readablestreaminterface) instead. The `addReadStream(resource $stream, callable $callback): void` method can be used to register a listener to be notified when a stream is ready to read. The first parameter MUST be a valid stream resource that supports checking whether it is ready to read by this loop implementation. A single stream resource MUST NOT be added more than once. Instead, either call [`removeReadStream()`](#removereadstream) first or react to this event with a single listener and then dispatch from this listener. This method MAY throw an `Exception` if the given resource type is not supported by this loop implementation. The listener callback function MUST be able to accept a single parameter, the stream resource added by this method or you MAY use a function which has no parameters at all. The listener callback function MUST NOT throw an `Exception`. The return value of the listener callback function will be ignored and has no effect, so for performance reasons you're recommended to not return any excessive data structures. If you want to access any variables within your callback function, you can bind arbitrary data to a callback closure like this: ```php $loop->addReadStream($stream, function ($stream) use ($name) { echo $name . ' said: ' . fread($stream); }); ``` See also [example #11](examples). You can invoke [`removeReadStream()`](#removereadstream) to remove the read event listener for this stream. The execution order of listeners when multiple streams become ready at the same time is not guaranteed. Some event loop implementations are known to only trigger the listener if the stream *becomes* readable (edge-triggered) and may not trigger if the stream has already been readable from the beginning. This also implies that a stream may not be recognized as readable when data is still left in PHP's internal stream buffers. As such, it's recommended to use `stream_set_read_buffer($stream, 0);` to disable PHP's internal read buffer in this case. #### addWriteStream() > Advanced! Note that this low-level API is considered advanced usage. Most use cases should probably use the higher-level [writable Stream API](https://github.com/reactphp/stream#writablestreaminterface) instead. The `addWriteStream(resource $stream, callable $callback): void` method can be used to register a listener to be notified when a stream is ready to write. The first parameter MUST be a valid stream resource that supports checking whether it is ready to write by this loop implementation. A single stream resource MUST NOT be added more than once. Instead, either call [`removeWriteStream()`](#removewritestream) first or react to this event with a single listener and then dispatch from this listener. This method MAY throw an `Exception` if the given resource type is not supported by this loop implementation. The listener callback function MUST be able to accept a single parameter, the stream resource added by this method or you MAY use a function which has no parameters at all. The listener callback function MUST NOT throw an `Exception`. The return value of the listener callback function will be ignored and has no effect, so for performance reasons you're recommended to not return any excessive data structures. If you want to access any variables within your callback function, you can bind arbitrary data to a callback closure like this: ```php $loop->addWriteStream($stream, function ($stream) use ($name) { fwrite($stream, 'Hello ' . $name); }); ``` See also [example #12](examples). You can invoke [`removeWriteStream()`](#removewritestream) to remove the write event listener for this stream. The execution order of listeners when multiple streams become ready at the same time is not guaranteed. #### removeReadStream() The `removeReadStream(resource $stream): void` method can be used to remove the read event listener for the given stream. Removing a stream from the loop that has already been removed or trying to remove a stream that was never added or is invalid has no effect. #### removeWriteStream() The `removeWriteStream(resource $stream): void` method can be used to remove the write event listener for the given stream. Removing a stream from the loop that has already been removed or trying to remove a stream that was never added or is invalid has no effect. ## Install The recommended way to install this library is [through Composer](https://getcomposer.org). [New to Composer?](https://getcomposer.org/doc/00-intro.md) This project follows [SemVer](https://semver.org/). This will install the latest supported version: ```bash $ composer require react/event-loop:^1.2 ``` See also the [CHANGELOG](CHANGELOG.md) for details about version upgrades. This project aims to run on any platform and thus does not require any PHP extensions and supports running on legacy PHP 5.3 through current PHP 8+ and HHVM. It's *highly recommended to use PHP 7+* for this project. Installing any of the event loop extensions is suggested, but entirely optional. See also [event loop implementations](#loop-implementations) for more details. ## Tests To run the test suite, you first need to clone this repo and then install all dependencies [through Composer](https://getcomposer.org): ```bash $ composer install ``` To run the test suite, go to the project root and run: ```bash $ php vendor/bin/phpunit ``` ## License MIT, see [LICENSE file](LICENSE). ## More * See our [Stream component](https://github.com/reactphp/stream) for more information on how streams are used in real-world applications. * See our [users wiki](https://github.com/reactphp/react/wiki/Users) and the [dependents on Packagist](https://packagist.org/packages/react/event-loop/dependents) for a list of packages that use the EventLoop in real-world applications.

[Install](#install) 6. [Credits](#credits) 7. [License](#license) Introduction ------------ Promise is a library implementing [CommonJS Promises/A](http://wiki.commonjs.org/wiki/Promises/A) for PHP. It also provides several other useful promise-related concepts, such as joining multiple promises and mapping and reducing collections of promises. If you've never heard about promises before, [read this first](https://gist.github.com/3889970). Concepts -------- ### Deferred A **Deferred** represents a computation or unit of work that may not have completed yet. Typically (but not always), that computation will be something that executes asynchronously and completes at some point in the future. ### Promise While a deferred represents the computation itself, a **Promise** represents the result of that computation. Thus, each deferred has a promise that acts as a placeholder for its actual result. API --- ### Deferred A deferred represents an operation whose resolution is pending. It has separate promise and resolver parts. ```php $deferred = new React\Promise\Deferred(); $promise = $deferred->promise(); $deferred->resolve(mixed $value = null); $deferred->reject(mixed $reason = null); $deferred->notify(mixed $update = null); ``` The `promise` method returns the promise of the deferred. The `resolve` and `reject` methods control the state of the deferred. The deprecated `notify` method is for progress notification. The constructor of the `Deferred` accepts an optional `$canceller` argument. See [Promise](#promise-2) for more information. #### Deferred::promise() ```php $promise = $deferred->promise(); ``` Returns the promise of the deferred, which you can hand out to others while keeping the authority to modify its state to yourself. #### Deferred::resolve() ```php $deferred->resolve(mixed $value = null); ``` Resolves the promise returned by `promise()`. All consumers are notified by having `$onFulfilled` (which they registered via `$promise->then()`) called with `$value`. If `$value` itself is a promise, the promise will transition to the state of this promise once it is resolved. #### Deferred::reject() ```php $deferred->reject(mixed $reason = null); ``` Rejects the promise returned by `promise()`, signalling that the deferred's computation failed. All consumers are notified by having `$onRejected` (which they registered via `$promise->then()`) called with `$reason`. If `$reason` itself is a promise, the promise will be rejected with the outcome of this promise regardless whether it fulfills or rejects. #### Deferred::notify() > Deprecated in v2.6.0: Progress support is deprecated and should not be used anymore. ```php $deferred->notify(mixed $update = null); ``` Triggers progress notifications, to indicate to consumers that the computation is making progress toward its result. All consumers are notified by having `$onProgress` (which they registered via `$promise->then()`) called with `$update`. ### PromiseInterface The promise interface provides the common interface for all promise implementations. A promise represents an eventual outcome, which is either fulfillment (success) and an associated value, or rejection (failure) and an associated reason. Once in the fulfilled or rejected state, a promise becomes immutable. Neither its state nor its result (or error) can be modified. #### Implementations * [Promise](#promise-2) * [FulfilledPromise](#fulfilledpromise) (deprecated) * [RejectedPromise](#rejectedpromise) (deprecated) * [LazyPromise](#lazypromise) (deprecated) #### PromiseInterface::then() ```php $transformedPromise = $promise->then(callable $onFulfilled = null, callable $onRejected = null, callable $onProgress = null); ``` Transforms a promise's value by applying a function to the promise's fulfillment or rejection value. Returns a new promise for the transformed result. The `then()` method registers new fulfilled, rejection and progress handlers with a promise (all parameters are optional): * `$onFulfilled` will be invoked once the promise is fulfilled and passed the result as the first argument. * `$onRejected` will be invoked once the promise is rejected and passed the reason as the first argument. * `$onProgress` (deprecated) will be invoked whenever the producer of the promise triggers progress notifications and passed a single argument (whatever it wants) to indicate progress. It returns a new promise that will fulfill with the return value of either `$onFulfilled` or `$onRejected`, whichever is called, or will reject with the thrown exception if either throws. A promise makes the following guarantees about handlers registered in the same call to `then()`: 1. Only one of `$onFulfilled` or `$onRejected` will be called, never both. 2. `$onFulfilled` and `$onRejected` will never be called more than once. 3. `$onProgress` (deprecated) may be called multiple times. #### See also * [resolve()](#resolve) - Creating a resolved promise * [reject()](#reject) - Creating a rejected promise * [ExtendedPromiseInterface::done()](#extendedpromiseinterfacedone) * [done() vs. then()](#done-vs-then) ### ExtendedPromiseInterface The ExtendedPromiseInterface extends the PromiseInterface with useful shortcut and utility methods which are not part of the Promises/A specification. #### Implementations * [Promise](#promise-1) * [FulfilledPromise](#fulfilledpromise) (deprecated) * [RejectedPromise](#rejectedpromise) (deprecated) * [LazyPromise](#lazypromise) (deprecated) #### ExtendedPromiseInterface::done() ```php $promise->done(callable $onFulfilled = null, callable $onRejected = null, callable $onProgress = null); ``` Consumes the promise's ultimate value if the promise fulfills, or handles the ultimate error. It will cause a fatal error if either `$onFulfilled` or `$onRejected` throw or return a rejected promise. Since the purpose of `done()` is consumption rather than transformation, `done()` always returns `null`. #### See also * [PromiseInterface::then()](#promiseinterfacethen) * [done() vs. then()](#done-vs-then) #### ExtendedPromiseInterface::otherwise() ```php $promise->otherwise(callable $onRejected); ``` Registers a rejection handler for promise. It is a shortcut for: ```php $promise->then(null, $onRejected); ``` Additionally, you can type hint the `$reason` argument of `$onRejected` to catch only specific errors. ```php $promise ->otherwise(function (\RuntimeException $reason) { // Only catch \RuntimeException instances // All other types of errors will propagate automatically }) ->otherwise(function ($reason) { // Catch other errors )}; ``` #### ExtendedPromiseInterface::always() ```php $newPromise = $promise->always(callable $onFulfilledOrRejected); ``` Allows you to execute "cleanup" type tasks in a promise chain. It arranges for `$onFulfilledOrRejected` to be called, with no arguments, when the promise is either fulfilled or rejected. * If `$promise` fulfills, and `$onFulfilledOrRejected` returns successfully, `$newPromise` will fulfill with the same value as `$promise`. * If `$promise` fulfills, and `$onFulfilledOrRejected` throws or returns a rejected promise, `$newPromise` will reject with the thrown exception or rejected promise's reason. * If `$promise` rejects, and `$onFulfilledOrRejected` returns successfully, `$newPromise` will reject with the same reason as `$promise`. * If `$promise` rejects, and `$onFulfilledOrRejected` throws or returns a rejected promise, `$newPromise` will reject with the thrown exception or rejected promise's reason. `always()` behaves similarly to the synchronous finally statement. When combined with `otherwise()`, `always()` allows you to write code that is similar to the familiar synchronous catch/finally pair. Consider the following synchronous code: ```php try { return doSomething(); } catch(\Exception $e) { return handleError($e); } finally { cleanup(); } ``` Similar asynchronous code (with `doSomething()` that returns a promise) can be written: ```php return doSomething() ->otherwise('handleError') ->always('cleanup'); ``` #### ExtendedPromiseInterface::progress() > Deprecated in v2.6.0: Progress support is deprecated and should not be used anymore. ```php $promise->progress(callable $onProgress); ``` Registers a handler for progress updates from promise. It is a shortcut for: ```php $promise->then(null, null, $onProgress); ``` ### CancellablePromiseInterface A cancellable promise provides a mechanism for consumers to notify the creator of the promise that they are not longer interested in the result of an operation. #### CancellablePromiseInterface::cancel() ``` php $promise->cancel(); ``` The `cancel()` method notifies the creator of the promise that there is no further interest in the results of the operation. Once a promise is settled (either fulfilled or rejected), calling `cancel()` on a promise has no effect. #### Implementations * [Promise](#promise-1) * [FulfilledPromise](#fulfilledpromise) (deprecated) * [RejectedPromise](#rejectedpromise) (deprecated) * [LazyPromise](#lazypromise) (deprecated) ### Promise Creates a promise whose state is controlled by the functions passed to `$resolver`. ```php $resolver = function (callable $resolve, callable $reject, callable $notify) { // Do some work, possibly asynchronously, and then // resolve or reject. You can notify of progress events (deprecated) // along the way if you want/need. $resolve($awesomeResult); // or throw new Exception('Promise rejected'); // or $resolve($anotherPromise); // or $reject($nastyError); // or $notify($progressNotification); }; $canceller = function () { // Cancel/abort any running operations like network connections, streams etc. // Reject promise by throwing an exception throw new Exception('Promise cancelled'); }; $promise = new React\Promise\Promise($resolver, $canceller); ``` The promise constructor receives a resolver function and an optional canceller function which both will be called with 3 arguments: * `$resolve($value)` - Primary function that seals the fate of the returned promise. Accepts either a non-promise value, or another promise. When called with a non-promise value, fulfills promise with that value. When called with another promise, e.g. `$resolve($otherPromise)`, promise's fate will be equivalent to that of `$otherPromise`. * `$reject($reason)` - Function that rejects the promise. It is recommended to just throw an exception instead of using `$reject()`. * `$notify($update)` - Deprecated function that issues progress events for the promise. If the resolver or canceller throw an exception, the promise will be rejected with that thrown exception as the rejection reason. The resolver function will be called immediately, the canceller function only once all consumers called the `cancel()` method of the promise. ### FulfilledPromise > Deprecated in v2.8.0: External usage of `FulfilledPromise` is deprecated, use `resolve()` instead. Creates a already fulfilled promise. ```php $promise = React\Promise\FulfilledPromise($value); ``` Note, that `$value` **cannot** be a promise. It's recommended to use [resolve()](#resolve) for creating resolved promises. ### RejectedPromise > Deprecated in v2.8.0: External usage of `RejectedPromise` is deprecated, use `reject()` instead. Creates a already rejected promise. ```php $promise = React\Promise\RejectedPromise($reason); ``` Note, that `$reason` **cannot** be a promise. It's recommended to use [reject()](#reject) for creating rejected promises. ### LazyPromise > Deprecated in v2.8.0: LazyPromise is deprecated and should not be used anymore. Creates a promise which will be lazily initialized by `$factory` once a consumer calls the `then()` method. ```php $factory = function () { $deferred = new React\Promise\Deferred(); // Do some heavy stuff here and resolve the deferred once completed return $deferred->promise(); }; $promise = new React\Promise\LazyPromise($factory); // $factory will only be executed once we call then() $promise->then(function ($value) { }); ``` ### Functions Useful functions for creating, joining, mapping and reducing collections of promises. All functions working on promise collections (like `all()`, `race()`, `some()` etc.) support cancellation. This means, if you call `cancel()` on the returned promise, all promises in the collection are cancelled. If the collection itself is a promise which resolves to an array, this promise is also cancelled. #### resolve() ```php $promise = React\Promise\resolve(mixed $promiseOrValue); ``` Creates a promise for the supplied `$promiseOrValue`. If `$promiseOrValue` is a value, it will be the resolution value of the returned promise. If `$promiseOrValue` is a thenable (any object that provides a `then()` method), a trusted promise that follows the state of the thenable is returned. If `$promiseOrValue` is a promise, it will be returned as is. Note: The promise returned is always a promise implementing [ExtendedPromiseInterface](#extendedpromiseinterface). If you pass in a custom promise which only implements [PromiseInterface](#promiseinterface), this promise will be assimilated to a extended promise following `$promiseOrValue`. #### reject() ```php $promise = React\Promise\reject(mixed $promiseOrValue); ``` Creates a rejected promise for the supplied `$promiseOrValue`. If `$promiseOrValue` is a value, it will be the rejection value of the returned promise. If `$promiseOrValue` is a promise, its completion value will be the rejected value of the returned promise. This can be useful in situations where you need to reject a promise without throwing an exception. For example, it allows you to propagate a rejection with the value of another promise. #### all() ```php $promise = React\Promise\all(array|React\Promise\PromiseInterface $promisesOrValues); ``` Returns a promise that will resolve only once all the items in `$promisesOrValues` have resolved. The resolution value of the returned promise will be an array containing the resolution values of each of the items in `$promisesOrValues`. #### race() ```php $promise = React\Promise\race(array|React\Promise\PromiseInterface $promisesOrValues); ``` Initiates a competitive race that allows one winner. Returns a promise which is resolved in the same way the first settled promise resolves. #### any() ```php $promise = React\Promise\any(array|React\Promise\PromiseInterface $promisesOrValues); ``` Returns a promise that will resolve when any one of the items in `$promisesOrValues` resolves. The resolution value of the returned promise will be the resolution value of the triggering item. The returned promise will only reject if *all* items in `$promisesOrValues` are rejected. The rejection value will be an array of all rejection reasons. The returned promise will also reject with a `React\Promise\Exception\LengthException` if `$promisesOrValues` contains 0 items. #### some() ```php $promise = React\Promise\some(array|React\Promise\PromiseInterface $promisesOrValues, integer $howMany); ``` Returns a promise that will resolve when `$howMany` of the supplied items in `$promisesOrValues` resolve. The resolution value of the returned promise will be an array of length `$howMany` containing the resolution values of the triggering items. The returned promise will reject if it becomes impossible for `$howMany` items to resolve (that is, when `(count($promisesOrValues) - $howMany) + 1` items reject). The rejection value will be an array of `(count($promisesOrValues) - $howMany) + 1` rejection reasons. The returned promise will also reject with a `React\Promise\Exception\LengthException` if `$promisesOrValues` contains less items than `$howMany`. #### map() ```php $promise = React\Promise\map(array|React\Promise\PromiseInterface $promisesOrValues, callable $mapFunc); ``` Traditional map function, similar to `array_map()`, but allows input to contain promises and/or values, and `$mapFunc` may return either a value or a promise. The map function receives each item as argument, where item is a fully resolved value of a promise or value in `$promisesOrValues`. #### reduce() ```php $promise = React\Promise\reduce(array|React\Promise\PromiseInterface $promisesOrValues, callable $reduceFunc , $initialValue = null); ``` Traditional reduce function, similar to `array_reduce()`, but input may contain promises and/or values, and `$reduceFunc` may return either a value or a promise, *and* `$initialValue` may be a promise or a value for the starting value. ### PromisorInterface The `React\Promise\PromisorInterface` provides a common interface for objects that provide a promise. `React\Promise\Deferred` implements it, but since it is part of the public API anyone can implement it. Examples -------- ### How to use Deferred ```php function getAwesomeResultPromise() { $deferred = new React\Promise\Deferred(); // Execute a Node.js-style function using the callback pattern computeAwesomeResultAsynchronously(function ($error, $result) use ($deferred) { if ($error) { $deferred->reject($error); } else { $deferred->resolve($result); } }); // Return the promise return $deferred->promise(); } getAwesomeResultPromise() ->then( function ($value) { // Deferred resolved, do something with $value }, function ($reason) { // Deferred rejected, do something with $reason }, function ($update) { // Progress notification triggered, do something with $update } ); ``` ### How promise forwarding works A few simple examples to show how the mechanics of Promises/A forwarding works. These examples are contrived, of course, and in real usage, promise chains will typically be spread across several function calls, or even several levels of your application architecture. #### Resolution forwarding Resolved promises forward resolution values to the next promise. The first promise, `$deferred->promise()`, will resolve with the value passed to `$deferred->resolve()` below. Each call to `then()` returns a new promise that will resolve with the return value of the previous handler. This creates a promise "pipeline". ```php $deferred = new React\Promise\Deferred(); $deferred->promise() ->then(function ($x) { // $x will be the value passed to $deferred->resolve() below // and returns a *new promise* for $x + 1 return $x + 1; }) ->then(function ($x) { // $x === 2 // This handler receives the return value of the // previous handler. return $x + 1; }) ->then(function ($x) { // $x === 3 // This handler receives the return value of the // previous handler. return $x + 1; }) ->then(function ($x) { // $x === 4 // This handler receives the return value of the // previous handler. echo 'Resolve ' . $x; }); $deferred->resolve(1); // Prints "Resolve 4" ``` #### Rejection forwarding Rejected promises behave similarly, and also work similarly to try/catch: When you catch an exception, you must rethrow for it to propagate. Similarly, when you handle a rejected promise, to propagate the rejection, "rethrow" it by either returning a rejected promise, or actually throwing (since promise translates thrown exceptions into rejections) ```php $deferred = new React\Promise\Deferred(); $deferred->promise() ->then(function ($x) { throw new \Exception($x + 1); }) ->otherwise(function (\Exception $x) { // Propagate the rejection throw $x; }) ->otherwise(function (\Exception $x) { // Can also propagate by returning another rejection return React\Promise\reject( new \Exception($x->getMessage() + 1) ); }) ->otherwise(function ($x) { echo 'Reject ' . $x->getMessage(); // 3 }); $deferred->resolve(1); // Prints "Reject 3" ``` #### Mixed resolution and rejection forwarding Just like try/catch, you can choose to propagate or not. Mixing resolutions and rejections will still forward handler results in a predictable way. ```php $deferred = new React\Promise\Deferred(); $deferred->promise() ->then(function ($x) { return $x + 1; }) ->then(function ($x) { throw new \Exception($x + 1); }) ->otherwise(function (\Exception $x) { // Handle the rejection, and don't propagate. // This is like catch without a rethrow return $x->getMessage() + 1; }) ->then(function ($x) { echo 'Mixed ' . $x; // 4 }); $deferred->resolve(1); // Prints "Mixed 4" ``` #### Progress event forwarding > Deprecated in v2.6.0: Progress support is deprecated and should not be used anymore. In the same way as resolution and rejection handlers, your progress handler **MUST** return a progress event to be propagated to the next link in the chain. If you return nothing, `null` will be propagated. Also in the same way as resolutions and rejections, if you don't register a progress handler, the update will be propagated through. If your progress handler throws an exception, the exception will be propagated to the next link in the chain. The best thing to do is to ensure your progress handlers do not throw exceptions. This gives you the opportunity to transform progress events at each step in the chain so that they are meaningful to the next step. It also allows you to choose not to transform them, and simply let them propagate untransformed, by not registering a progress handler. ```php $deferred = new React\Promise\Deferred(); $deferred->promise() ->progress(function ($update) { return $update + 1; }) ->progress(function ($update) { echo 'Progress ' . $update; // 2 }); $deferred->notify(1); // Prints "Progress 2" ``` ### done() vs. then() The golden rule is: Either return your promise, or call done() on it. At a first glance, `then()` and `done()` seem very similar. However, there are important distinctions. The intent of `then()` is to transform a promise's value and to pass or return a new promise for the transformed value along to other parts of your code. The intent of `done()` is to consume a promise's value, transferring responsibility for the value to your code. In addition to transforming a value, `then()` allows you to recover from, or propagate intermediate errors. Any errors that are not handled will be caught by the promise machinery and used to reject the promise returned by `then()`. Calling `done()` transfers all responsibility for errors to your code. If an error (either a thrown exception or returned rejection) escapes the `$onFulfilled` or `$onRejected` callbacks you provide to done, it will be rethrown in an uncatchable way causing a fatal error. ```php function getJsonResult() { return queryApi() ->then( // Transform API results to an object function ($jsonResultString) { return json_decode($jsonResultString); }, // Transform API errors to an exception function ($jsonErrorString) { $object = json_decode($jsonErrorString); throw new ApiErrorException($object->errorMessage); } ); } // Here we provide no rejection handler. If the promise returned has been // rejected, the ApiErrorException will be thrown getJsonResult() ->done( // Consume transformed object function ($jsonResultObject) { // Do something with $jsonResultObject } ); // Here we provide a rejection handler which will either throw while debugging // or log the exception getJsonResult() ->done( function ($jsonResultObject) { // Do something with $jsonResultObject }, function (ApiErrorException $exception) { if (isDebug()) { throw $exception; } else { logException($exception); } } ); ``` Note that if a rejection value is not an instance of `\Exception`, it will be wrapped in an exception of the type `React\Promise\UnhandledRejectionException`. You can get the original rejection reason by calling `$exception->getReason()`. Install ------- The recommended way to install this library is [through Composer](https://getcomposer.org). [New to Composer?](https://getcomposer.org/doc/00-intro.md) This project follows [SemVer](https://semver.org/). This will install the latest supported version: ```bash $ composer require react/promise:^2.8 ``` See also the [CHANGELOG](CHANGELOG.md) for details about version upgrades. This project aims to run on any platform and thus does not require any PHP extensions and supports running on legacy PHP 5.4 through current PHP 7+ and HHVM. It's *highly recommended to use PHP 7+* for this project due to its vast performance improvements.

(#269 by @clue) ```php $socket = new React\Socket\SocketSever('php://fd/3'); ``` This is particularly useful when using [systemd socket activation](https://www.freedesktop.org/software/systemd/man/systemd.socket.html) like this: ```bash $ systemd-socket-activate -l 8000 php examples/03-http-server.php php://fd/3 ``` * Feature: Improve error messages for failed connection attempts with `errno` and `errstr`. (#265, #266, #267, #270 and #271 by @clue and #268 by @SimonFrings) All error messages now always include the appropriate `errno` and `errstr` to give more details about the error reason when available. Along with these error details exposed by the underlying system functions, it will also include the appropriate error constant name (such as `ECONNREFUSED`) when available. Accordingly, failed TCP/IP connections will now report the actual underlying error condition instead of a generic "Connection refused" error. Higher-level error messages will now consistently report the connection URI scheme and hostname used in all error messages. For most common use cases this means that simply reporting the `Exception` message should give the most relevant details for any connection issues: ```php $connector = new React\Socket\Connector(); $connector->connect($uri)->then(function (React\Socket\ConnectionInterface $conn) { // … }, function (Exception $e) { echo 'Error:' . $e->getMessage() . PHP_EOL; }); ``` * Improve test suite, test against PHP 8.1 release. (#274 by @SimonFrings) ## 1.9.0 (2021-08-03) * Feature: Add new `SocketServer` and deprecate `Server` to avoid class name collisions. (#263 by @clue) The new `SocketServer` class has been added with an improved constructor signature as a replacement for the previous `Server` class in order to avoid any ambiguities. The previous name has been deprecated and should not be used anymore. In its most basic form, the deprecated `Server` can now be considered an alias for new `SocketServer`. ```php // deprecated $socket = new React\Socket\Server(0); $socket = new React\Socket\Server('127.0.0.1:8000'); $socket = new React\Socket\Server('127.0.0.1:8000', null, $context); $socket = new React\Socket\Server('127.0.0.1:8000', $loop, $context); // new $socket = new React\Socket\SocketServer('127.0.0.1:0'); $socket = new React\Socket\SocketServer('127.0.0.1:8000'); $socket = new React\Socket\SocketServer('127.0.0.1:8000', $context); $socket = new React\Socket\SocketServer('127.0.0.1:8000', $context, $loop); ``` * Feature: Update `Connector` signature to take optional `$context` as first argument. (#264 by @clue) The new signature has been added to match the new `SocketServer` and consistently move the now commonly unneeded loop argument to the last argument. The previous signature has been deprecated and should not be used anymore. In its most basic form, both signatures are compatible. ```php // deprecated $connector = new React\Socket\Connector(null, $context); $connector = new React\Socket\Connector($loop, $context); // new $connector = new React\Socket\Connector($context); $connector = new React\Socket\Connector($context, $loop); ``` ## 1.8.0 (2021-07-11) A major new feature release, see [**release announcement**](https://clue.engineering/2021/announcing-reactphp-default-loop). * Feature: Simplify usage by supporting new [default loop](https://reactphp.org/event-loop/#loop). (#260 by @clue) ```php // old (still supported) $socket = new React\Socket\Server('127.0.0.1:8080', $loop); $connector = new React\Socket\Connector($loop); // new (using default loop) $socket = new React\Socket\Server('127.0.0.1:8080'); $connector = new React\Socket\Connector(); ``` ## 1.7.0 (2021-06-25) * Feature: Support falling back to multiple DNS servers from DNS config. (#257 by @clue) If you're using the default `Connector`, it will now use all DNS servers configured on your system. If you have multiple DNS servers configured and connectivity to the primary DNS server is broken, it will now fall back to your other DNS servers, thus providing improved connectivity and redundancy for broken DNS configurations. * Feature: Use round robin for happy eyeballs DNS responses (load balancing). (#247 by @clue) If you're using the default `Connector`, it will now randomize the order of the IP addresses resolved via DNS when connecting. This allows the load to be distributed more evenly across all returned IP addresses. This can be used as a very basic DNS load balancing mechanism. * Internal improvement to avoid unhandled rejection for future Promise API. (#258 by @clue) * Improve test suite, use GitHub actions for continuous integration (CI). (#254 by @SimonFrings) ## 1.6.0 (2020-08-28) * Feature: Support upcoming PHP 8 release. (#246 by @clue) * Feature: Change default socket backlog size to 511. (#242 by @clue) * Fix: Fix closing connection when cancelling during TLS handshake. (#241 by @clue) * Fix: Fix blocking during possible `accept()` race condition when multiple socket servers listen on same socket address. (#244 by @clue) * Improve test suite, update PHPUnit config and add full core team to the license. (#243 by @SimonFrings and #245 by @WyriHaximus) ## 1.5.0 (2020-07-01) * Feature / Fix: Improve error handling and reporting for happy eyeballs and immediately try next connection when one connection attempt fails. (#230, #231, #232 and #233 by @clue) Error messages for failed connection attempts now include more details to ease debugging. Additionally, the happy eyeballs algorithm has been improved to avoid having to wait for some timers to expire which significantly improves connection setup times (in particular when IPv6 isn't available). * Improve test suite, minor code cleanup and improve code coverage to 100%. Update to PHPUnit 9 and skip legacy TLS 1.0 / TLS 1.1 tests if disabled by system. Run tests on Windows and simplify Travis CI test matrix for Mac OS X setup and skip all TLS tests on legacy HHVM. (#229, #235, #236 and #238 by @clue and #239 by @SimonFrings) ## 1.4.0 (2020-03-12) A major new feature release, see [**release announcement**](https://clue.engineering/2020/introducing-ipv6-for-reactphp). * Feature: Add IPv6 support to `Connector` (implement "Happy Eyeballs" algorithm to support IPv6 probing). IPv6 support is turned on by default, use new `happy_eyeballs` option in `Connector` to toggle behavior. (#196, #224 and #225 by @WyriHaximus and @clue) * Feature: Default to using DNS cache (with max 256 entries) for `Connector`. (#226 by @clue) * Add `.gitattributes` to exclude dev files from exports and some minor code style fixes. (#219 by @reedy and #218 by @mmoreram) * Improve test suite to fix failing test cases when using new DNS component, significantly improve test performance by awaiting events instead of sleeping, exclude TLS 1.3 test on PHP 7.3, run tests on PHP 7.4 and simplify test matrix. (#208, #209, #210, #217 and #223 by @clue) ## 1.3.0 (2019-07-10) * Feature: Forward compatibility with upcoming stable DNS component. (#206 by @clue) ## 1.2.1 (2019-06-03) * Avoid uneeded fragmented TLS work around for PHP 7.3.3+ and work around failing test case detecting EOF on TLS 1.3 socket streams. (#201 and #202 by @clue) * Improve TLS certificate/passphrase example. (#190 by @jsor) ## 1.2.0 (2019-01-07) * Feature / Fix: Improve TLS 1.3 support. (#186 by @clue) TLS 1.3 is now an official standard as of August 2018! :tada: The protocol has major improvements in the areas of security, performance, and privacy. TLS 1.3 is supported by default as of [OpenSSL 1.1.1](https://www.openssl.org/blog/blog/2018/09/11/release111/). For example, this version ships with Ubuntu 18.10 (and newer) by default, meaning that recent installations support TLS 1.3 out of the box :shipit: * Fix: Avoid possibility of missing remote address when TLS handshake fails. (#188 by @clue) * Improve performance by prefixing all global functions calls with `\` to skip the look up and resolve process and go straight to the global function. (#183 by @WyriHaximus) * Update documentation to use full class names with namespaces. (#187 by @clue) * Improve test suite to avoid some possible race conditions, test against PHP 7.3 on Travis and use dedicated `assertInstanceOf()` assertions. (#185 by @clue, #178 by @WyriHaximus and #181 by @carusogabriel) ## 1.1.0 (2018-10-01) * Feature: Improve error reporting for failed connection attempts and improve cancellation forwarding during DNS lookup, TCP/IP connection or TLS handshake. (#168, #169, #170, #171, #176 and #177 by @clue) All error messages now always contain a reference to the remote URI to give more details which connection actually failed and the reason for this error. Accordingly, failures during DNS lookup will now mention both the remote URI as well as the DNS error reason. TCP/IP connection issues and errors during a secure TLS handshake will both mention the remote URI as well as the underlying socket error. Similarly, lost/dropped connections during a TLS handshake will now report a lost connection instead of an empty error reason. For most common use cases this means that simply reporting the `Exception` message should give the most relevant details for any connection issues: ```php $promise = $connector->connect('tls://example.com:443'); $promise->then(function (ConnectionInterface $conn) use ($loop) { // … }, function (Exception $e) { echo $e->getMessage(); }); ``` ## 1.0.0 (2018-07-11) * First stable LTS release, now following [SemVer](https://semver.org/). We'd like to emphasize that this component is production ready and battle-tested. We plan to support all long-term support (LTS) releases for at least 24 months, so you have a rock-solid foundation to build on top of. > Contains no other changes, so it's actually fully compatible with the v0.8.12 release. ## 0.8.12 (2018-06-11) * Feature: Improve memory consumption for failed and cancelled connection attempts. (#161 by @clue) * Improve test suite to fix Travis config to test against legacy PHP 5.3 again. (#162 by @clue) ## 0.8.11 (2018-04-24) * Feature: Improve memory consumption for cancelled connection attempts and simplify skipping DNS lookup when connecting to IP addresses. (#159 and #160 by @clue) ## 0.8.10 (2018-02-28) * Feature: Update DNS dependency to support loading system default DNS nameserver config on all supported platforms (`/etc/resolv.conf` on Unix/Linux/Mac/Docker/WSL and WMIC on Windows) (#152 by @clue) This means that connecting to hosts that are managed by a local DNS server, such as a corporate DNS server or when using Docker containers, will now work as expected across all platforms with no changes required: ```php $connector = new Connector($loop); $connector->connect('intranet.example:80')->then(function ($connection) { // … }); ``` ## 0.8.9 (2018-01-18) * Feature: Support explicitly choosing TLS version to negotiate with remote side by respecting `crypto_method` context parameter for all classes. (#149 by @clue) By default, all connector and server classes support TLSv1.0+ and exclude support for legacy SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly choose the TLS version you want to negotiate with the remote side: ```php // new: now supports 'crypto_method` context parameter for all classes $connector = new Connector($loop, array( 'tls' => array( 'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT ) )); ``` * Minor internal clean up to unify class imports (#148 by @clue) ## 0.8.8 (2018-01-06) * Improve test suite by adding test group to skip integration tests relying on internet connection and fix minor documentation typo. (#146 by @clue and #145 by @cn007b) ## 0.8.7 (2017-12-24) * Fix: Fix closing socket resource before removing from loop (#141 by @clue) This fixes the root cause of an uncaught `Exception` that only manifested itself after the recent Stream v0.7.4 component update and only if you're using `ext-event` (`ExtEventLoop`). * Improve test suite by testing against PHP 7.2 (#140 by @carusogabriel) ## 0.8.6 (2017-11-18) * Feature: Add Unix domain socket (UDS) support to `Server` with `unix://` URI scheme and add advanced `UnixServer` class. (#120 by @andig) ```php // new: Server now supports "unix://" scheme $server = new Server('unix:///tmp/server.sock', $loop); // new: advanced usage $server = new UnixServer('/tmp/server.sock', $loop); ``` * Restructure examples to ease getting started (#136 by @clue) * Improve test suite by adding forward compatibility with PHPUnit 6 and ignore Mac OS X test failures for now until Travis tests work again (#133 by @gabriel-caruso and #134 by @clue) ## 0.8.5 (2017-10-23) * Fix: Work around PHP bug with Unix domain socket (UDS) paths for Mac OS X (#123 by @andig) * Fix: Fix `SecureServer` to return `null` URI if server socket is already closed (#129 by @clue) * Improve test suite by adding forward compatibility with PHPUnit v5 and forward compatibility with upcoming EventLoop releases in tests and test Mac OS X on Travis (#122 by @andig and #125, #127 and #130 by @clue) * Readme improvements (#118 by @jsor) ## 0.8.4 (2017-09-16) * Feature: Add `FixedUriConnector` decorator to use fixed, preconfigured URI instead (#117 by @clue) This can be useful for consumers that do not support certain URIs, such as when you want to explicitly connect to a Unix domain socket (UDS) path instead of connecting to a default address assumed by an higher-level API: ```php $connector = new FixedUriConnector( 'unix:///var/run/docker.sock', new UnixConnector($loop) ); // destination will be ignored, actually connects to Unix domain socket $promise = $connector->connect('localhost:80'); ``` ## 0.8.3 (2017-09-08) * Feature: Reduce memory consumption for failed connections (#113 by @valga) * Fix: Work around write chunk size for TLS streams for PHP < 7.1.14 (#114 by @clue) ## 0.8.2 (2017-08-25) * Feature: Update DNS dependency to support hosts file on all platforms (#112 by @clue) This means that connecting to hosts such as `localhost` will now work as expected across all platforms with no changes required: ```php $connector = new Connector($loop); $connector->connect('localhost:8080')->then(function ($connection) { // … }); ``` ## 0.8.1 (2017-08-15) * Feature: Forward compatibility with upcoming EventLoop v1.0 and v0.5 and target evenement 3.0 a long side 2.0 and 1.0 (#104 by @clue and #111 by @WyriHaximus) * Improve test suite by locking Travis distro so new defaults will not break the build and fix HHVM build for now again and ignore future HHVM build errors (#109 and #110 by @clue) * Minor documentation fixes (#103 by @christiaan and #108 by @hansott) ## 0.8.0 (2017-05-09) * Feature: New `Server` class now acts as a facade for existing server classes and renamed old `Server` to `TcpServer` for advanced usage. (#96 and #97 by @clue) The `Server` class is now the main class in this package that implements the `ServerInterface` and allows you to accept incoming streaming connections, such as plaintext TCP/IP or secure TLS connection streams. > This is not a BC break and consumer code does not have to be updated. * Feature / BC break: All addresses are now URIs that include the URI scheme (#98 by @clue) ```diff - $parts = parse_url('tcp://' . $conn->getRemoteAddress()); + $parts = parse_url($conn->getRemoteAddress()); ``` * Fix: Fix `unix://` addresses for Unix domain socket (UDS) paths (#100 by @clue) * Feature: Forward compatibility with Stream v1.0 and v0.7 (#99 by @clue) ## 0.7.2 (2017-04-24) * Fix: Work around latest PHP 7.0.18 and 7.1.4 no longer accepting full URIs (#94 by @clue) ## 0.7.1 (2017-04-10) * Fix: Ignore HHVM errors when closing connection that is already closing (#91 by @clue) ## 0.7.0 (2017-04-10) * Feature: Merge SocketClient component into this component (#87 by @clue) This means that this package now provides async, streaming plaintext TCP/IP and secure TLS socket server and client connections for ReactPHP. ``` $connector = new React\Socket\Connector($loop); $connector->connect('google.com:80')->then(function (ConnectionInterface $conn) { $connection->write('…'); }); ``` Accordingly, the `ConnectionInterface` is now used to represent both incoming server side connections as well as outgoing client side connections. If you've previously used the SocketClient component to establish outgoing client connections, upgrading should take no longer than a few minutes. All classes have been merged as-is from the latest `v0.7.0` release with no other changes, so you can simply update your code to use the updated namespace like this: ```php // old from SocketClient component and namespace $connector = new React\SocketClient\Connector($loop); $connector->connect('google.com:80')->then(function (ConnectionInterface $conn) { $connection->write('…'); }); // new $connector = new React\Socket\Connector($loop); $connector->connect('google.com:80')->then(function (ConnectionInterface $conn) { $connection->write('…'); }); ``` ## 0.6.0 (2017-04-04) * Feature: Add `LimitingServer` to limit and keep track of open connections (#86 by @clue) ```php $server = new Server(0, $loop); $server = new LimitingServer($server, 100); $server->on('connection', function (ConnectionInterface $connection) { $connection->write('hello there!' . PHP_EOL); … }); ``` * Feature / BC break: Add `pause()` and `resume()` methods to limit active connections (#84 by @clue) ```php $server = new Server(0, $loop); $server->pause(); $loop->addTimer(1.0, function() use ($server) { $server->resume(); }); ``` ## 0.5.1 (2017-03-09) * Feature: Forward compatibility with Stream v0.5 and upcoming v0.6 (#79 by @clue) ## 0.5.0 (2017-02-14) * Feature / BC break: Replace `listen()` call with URIs passed to constructor and reject listening on hostnames with `InvalidArgumentException` and replace `ConnectionException` with `RuntimeException` for consistency (#61, #66 and #72 by @clue) ```php // old $server = new Server($loop); $server->listen(8080); // new $server = new Server(8080, $loop); ``` Similarly, you can now pass a full listening URI to the constructor to change the listening host: ```php // old $server = new Server($loop); $server->listen(8080, '127.0.0.1'); // new $server = new Server('127.0.0.1:8080', $loop); ``` Trying to start listening on (DNS) host names will now throw an `InvalidArgumentException`, use IP addresses instead: ```php // old $server = new Server($loop); $server->listen(8080, 'localhost'); // new $server = new Server('127.0.0.1:8080', $loop); ``` If trying to listen fails (such as if port is already in use or port below 1024 may require root access etc.), it will now throw a `RuntimeException`, the `ConnectionException` class has been removed: ```php // old: throws React\Socket\ConnectionException $server = new Server($loop); $server->listen(80); // new: throws RuntimeException $server = new Server(80, $loop); ``` * Feature / BC break: Rename `shutdown()` to `close()` for consistency throughout React (#62 by @clue) ```php // old $server->shutdown(); // new $server->close(); ``` * Feature / BC break: Replace `getPort()` with `getAddress()` (#67 by @clue) ```php // old echo $server->getPort(); // 8080 // new echo $server->getAddress(); // 127.0.0.1:8080 ``` * Feature / BC break: `getRemoteAddress()` returns full address instead of only IP (#65 by @clue) ```php // old echo $connection->getRemoteAddress(); // 192.168.0.1 // new echo $connection->getRemoteAddress(); // 192.168.0.1:51743 ``` * Feature / BC break: Add `getLocalAddress()` method (#68 by @clue) ```php echo $connection->getLocalAddress(); // 127.0.0.1:8080 ``` * BC break: The `Server` and `SecureServer` class are now marked `final` and you can no longer `extend` them (which was never documented or recommended anyway). Public properties and event handlers are now internal only. Please use composition instead of extension.

The socket library provides re-usable interfaces for a socket-layer server and client based on the [`EventLoop`](https://github.com/reactphp/event-loop) and [`Stream`](https://github.com/reactphp/stream) components. Its server component allows you to build networking servers that accept incoming connections from networking clients (such as an HTTP server). Its client component allows you to build networking clients that establish outgoing connections to networking servers (such as an HTTP or database client). This library provides async, streaming means for all of this, so you can handle multiple concurrent connections without blocking. **Table of Contents** * [Quickstart example](#quickstart-example) * [Connection usage](#connection-usage) * [ConnectionInterface](#connectioninterface) * [getRemoteAddress()](#getremoteaddress) * [getLocalAddress()](#getlocaladdress) * [Server usage](#server-usage) * [ServerInterface](#serverinterface) * [connection event](#connection-event) * [error event](#error-event) * [getAddress()](#getaddress) * [pause()](#pause) * [resume()](#resume) * [close()](#close) * [SocketServer](#socketserver) * [Advanced server usage](#advanced-server-usage) * [TcpServer](#tcpserver) * [SecureServer](#secureserver) * [UnixServer](#unixserver) * [LimitingServer](#limitingserver) * [getConnections()](#getconnections) * [Client usage](#client-usage) * [ConnectorInterface](#connectorinterface) * [connect()](#connect) * [Connector](#connector) * [Advanced client usage](#advanced-client-usage) * [TcpConnector](#tcpconnector) * [HappyEyeBallsConnector](#happyeyeballsconnector) * [DnsConnector](#dnsconnector) * [SecureConnector](#secureconnector) * [TimeoutConnector](#timeoutconnector) * [UnixConnector](#unixconnector) * [FixUriConnector](#fixeduriconnector) * [Install](#install) * [Tests](#tests) * [License](#license) ## Quickstart example Here is a server that closes the connection if you send it anything: ```php $socket = new React\Socket\SocketServer('127.0.0.1:8080'); $socket->on('connection', function (React\Socket\ConnectionInterface $connection) { $connection->write("Hello " . $connection->getRemoteAddress() . "!\n"); $connection->write("Welcome to this amazing server!\n"); $connection->write("Here's a tip: don't say anything.\n"); $connection->on('data', function ($data) use ($connection) { $connection->close(); }); }); ``` See also the [examples](examples). Here's a client that outputs the output of said server and then attempts to send it a string: ```php $connector = new React\Socket\Connector(); $connector->connect('127.0.0.1:8080')->then(function (React\Socket\ConnectionInterface $connection) { $connection->pipe(new React\Stream\WritableResourceStream(STDOUT)); $connection->write("Hello World!\n"); }, function (Exception $e) { echo 'Error: ' . $e->getMessage() . PHP_EOL; }); ``` ## Connection usage ### ConnectionInterface The `ConnectionInterface` is used to represent any incoming and outgoing connection, such as a normal TCP/IP connection. An incoming or outgoing connection is a duplex stream (both readable and writable) that implements React's [`DuplexStreamInterface`](https://github.com/reactphp/stream#duplexstreaminterface). It contains additional properties for the local and remote address (client IP) where this connection has been established to/from. Most commonly, instances implementing this `ConnectionInterface` are emitted by all classes implementing the [`ServerInterface`](#serverinterface) and used by all classes implementing the [`ConnectorInterface`](#connectorinterface). Because the `ConnectionInterface` implements the underlying [`DuplexStreamInterface`](https://github.com/reactphp/stream#duplexstreaminterface) you can use any of its events and methods as usual: ```php $connection->on('data', function ($chunk) { echo $chunk; }); $connection->on('end', function () { echo 'ended'; }); $connection->on('error', function (Exception $e) { echo 'error: ' . $e->getMessage(); }); $connection->on('close', function () { echo 'closed'; }); $connection->write($data); $connection->end($data = null); $connection->close(); // … ``` For more details, see the [`DuplexStreamInterface`](https://github.com/reactphp/stream#duplexstreaminterface). #### getRemoteAddress() The `getRemoteAddress(): ?string` method returns the full remote address (URI) where this connection has been established with. ```php $address = $connection->getRemoteAddress(); echo 'Connection with ' . $address . PHP_EOL; ``` If the remote address can not be determined or is unknown at this time (such as after the connection has been closed), it MAY return a `NULL` value instead. Otherwise, it will return the full address (URI) as a string value, such as `tcp://127.0.0.1:8080`, `tcp://[::1]:80`, `tls://127.0.0.1:443`, `unix://example.sock` or `unix:///path/to/example.sock`. Note that individual URI components are application specific and depend on the underlying transport protocol. If this is a TCP/IP based connection and you only want the remote IP, you may use something like this: ```php $address = $connection->getRemoteAddress(); $ip = trim(parse_url($address, PHP_URL_HOST), '[]'); echo 'Connection with ' . $ip . PHP_EOL; ``` #### getLocalAddress() The `getLocalAddress(): ?string` method returns the full local address (URI) where this connection has been established with. ```php $address = $connection->getLocalAddress(); echo 'Connection with ' . $address . PHP_EOL; ``` If the local address can not be determined or is unknown at this time (such as after the connection has been closed), it MAY return a `NULL` value instead. Otherwise, it will return the full address (URI) as a string value, such as `tcp://127.0.0.1:8080`, `tcp://[::1]:80`, `tls://127.0.0.1:443`, `unix://example.sock` or `unix:///path/to/example.sock`. Note that individual URI components are application specific and depend on the underlying transport protocol. This method complements the [`getRemoteAddress()`](#getremoteaddress) method, so they should not be confused. If your `TcpServer` instance is listening on multiple interfaces (e.g. using the address `0.0.0.0`), you can use this method to find out which interface actually accepted this connection (such as a public or local interface). If your system has multiple interfaces (e.g. a WAN and a LAN interface), you can use this method to find out which interface was actually used for this connection. ## Server usage ### ServerInterface The `ServerInterface` is responsible for providing an interface for accepting incoming streaming connections, such as a normal TCP/IP connection. Most higher-level components (such as a HTTP server) accept an instance implementing this interface to accept incoming streaming connections. This is usually done via dependency injection, so it's fairly simple to actually swap this implementation against any other implementation of this interface. This means that you SHOULD typehint against this interface instead of a concrete implementation of this interface. Besides defining a few methods, this interface also implements the [`EventEmitterInterface`](https://github.com/igorw/evenement) which allows you to react to certain events. #### connection event The `connection` event will be emitted whenever a new connection has been established, i.e. a new client connects to this server socket: ```php $socket->on('connection', function (React\Socket\ConnectionInterface $connection) { echo 'new connection' . PHP_EOL; }); ``` See also the [`ConnectionInterface`](#connectioninterface) for more details about handling the incoming connection. #### error event The `error` event will be emitted whenever there's an error accepting a new connection from a client. ```php $socket->on('error', function (Exception $e) { echo 'error: ' . $e->getMessage() . PHP_EOL; }); ``` Note that this is not a fatal error event, i.e. the server keeps listening for new connections even after this event. #### getAddress() The `getAddress(): ?string` method can be used to return the full address (URI) this server is currently listening on. ```php $address = $socket->getAddress(); echo 'Server listening on ' . $address . PHP_EOL; ``` If the address can not be determined or is unknown at this time (such as after the socket has been closed), it MAY return a `NULL` value instead. Otherwise, it will return the full address (URI) as a string value, such as `tcp://127.0.0.1:8080`, `tcp://[::1]:80`, `tls://127.0.0.1:443` `unix://example.sock` or `unix:///path/to/example.sock`. Note that individual URI components are application specific and depend on the underlying transport protocol. If this is a TCP/IP based server and you only want the local port, you may use something like this: ```php $address = $socket->getAddress(); $port = parse_url($address, PHP_URL_PORT); echo 'Server listening on port ' . $port . PHP_EOL; ``` #### pause() The `pause(): void` method can be used to pause accepting new incoming connections. Removes the socket resource from the EventLoop and thus stop accepting new connections. Note that the listening socket stays active and is not closed. This means that new incoming connections will stay pending in the operating system backlog until its configurable backlog is filled. Once the backlog is filled, the operating system may reject further incoming connections until the backlog is drained again by resuming to accept new connections. Once the server is paused, no futher `connection` events SHOULD be emitted. ```php $socket->pause(); $socket->on('connection', assertShouldNeverCalled()); ``` This method is advisory-only, though generally not recommended, the server MAY continue emitting `connection` events. Unless otherwise noted, a successfully opened server SHOULD NOT start in paused state. You can continue processing events by calling `resume()` again. Note that both methods can be called any number of times, in particular calling `pause()` more than once SHOULD NOT have any effect. Similarly, calling this after `close()` is a NO-OP. #### resume() The `resume(): void` method can be used to resume accepting new incoming connections. Re-attach the socket resource to the EventLoop after a previous `pause()`. ```php $socket->pause(); Loop::addTimer(1.0, function () use ($socket) { $socket->resume(); }); ``` Note that both methods can be called any number of times, in particular calling `resume()` without a prior `pause()` SHOULD NOT have any effect. Similarly, calling this after `close()` is a NO-OP. #### close() The `close(): void` method can be used to shut down this listening socket. This will stop listening for new incoming connections on this socket. ```php echo 'Shutting down server socket' . PHP_EOL; $socket->close(); ``` Calling this method more than once on the same instance is a NO-OP. ### SocketServer <a id="server"></a> <!-- legacy id --> The `SocketServer` class is the main class in this package that implements the [`ServerInterface`](#serverinterface) and allows you to accept incoming streaming connections, such as plaintext TCP/IP or secure TLS connection streams. In order to accept plaintext TCP/IP connections, you can simply pass a host and port combination like this: ```php $socket = new React\Socket\SocketServer('127.0.0.1:8080'); ``` Listening on the localhost address `127.0.0.1` means it will not be reachable from outside of this system. In order to change the host the socket is listening on, you can provide an IP address of an interface or use the special `0.0.0.0` address to listen on all interfaces: ```php $socket = new React\Socket\SocketServer('0.0.0.0:8080'); ``` If you want to listen on an IPv6 address, you MUST enclose the host in square brackets: ```php $socket = new React\Socket\SocketServer('[::1]:8080'); ``` In order to use a random port assignment, you can use the port `0`: ```php $socket = new React\Socket\SocketServer('127.0.0.1:0'); $address = $socket->getAddress(); ``` To listen on a Unix domain socket (UDS) path, you MUST prefix the URI with the `unix://` scheme: ```php $socket = new React\Socket\SocketServer('unix:///tmp/server.sock'); ``` In order to listen on an existing file descriptor (FD) number, you MUST prefix the URI with `php://fd/` like this: ```php $socket = new React\Socket\SocketServer('php://fd/3'); ``` If the given URI is invalid, does not contain a port, any other scheme or if it contains a hostname, it will throw an `InvalidArgumentException`: ```php // throws InvalidArgumentException due to missing port $socket = new React\Socket\SocketServer('127.0.0.1'); ``` If the given URI appears to be valid, but listening on it fails (such as if port is already in use or port below 1024 may require root access etc.), it will throw a `RuntimeException`: ```php $first = new React\Socket\SocketServer('127.0.0.1:8080'); // throws RuntimeException because port is already in use $second = new React\Socket\SocketServer('127.0.0.1:8080'); ``` > Note that these error conditions may vary depending on your system and/or configuration. See the exception message and code for more details about the actual error condition. Optionally, you can specify [TCP socket context options](https://www.php.net/manual/en/context.socket.php) for the underlying stream socket resource like this: ```php $socket = new React\Socket\SocketServer('[::1]:8080', array( 'tcp' => array( 'backlog' => 200, 'so_reuseport' => true, 'ipv6_v6only' => true ) )); ``` > Note that available [socket context options](https://www.php.net/manual/en/context.socket.php), their defaults and effects of changing these may vary depending on your system and/or PHP version. Passing unknown context options has no effect. The `backlog` context option defaults to `511` unless given explicitly. You can start a secure TLS (formerly known as SSL) server by simply prepending the `tls://` URI scheme. Internally, it will wait for plaintext TCP/IP connections and then performs a TLS handshake for each connection. It thus requires valid [TLS context options](https://www.php.net/manual/en/context.ssl.php), which in its most basic form may look something like this if you're using a PEM encoded certificate file: ```php $socket = new React\Socket\SocketServer('tls://127.0.0.1:8080', array( 'tls' => array( 'local_cert' => 'server.pem' ) )); ``` > Note that the certificate file will not be loaded on instantiation but when an incoming connection initializes its TLS context. This implies that any invalid certificate file paths or contents will only cause an `error` event at a later time. If your private key is encrypted with a passphrase, you have to specify it like this: ```php $socket = new React\Socket\SocketServer('tls://127.0.0.1:8000', array( 'tls' => array( 'local_cert' => 'server.pem', 'passphrase' => 'secret' ) )); ``` By default, this server supports TLSv1.0+ and excludes support for legacy SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly choose the TLS version you want to negotiate with the remote side: ```php $socket = new React\Socket\SocketServer('tls://127.0.0.1:8000', array( 'tls' => array( 'local_cert' => 'server.pem', 'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_SERVER ) )); ``` > Note that available [TLS context options](https://www.php.net/manual/en/context.ssl.php), their defaults and effects of changing these may vary depending on your system and/or PHP version. The outer context array allows you to also use `tcp` (and possibly more) context options at the same time. Passing unknown context options has no effect. If you do not use the `tls://` scheme, then passing `tls` context options has no effect. Whenever a client connects, it will emit a `connection` event with a connection instance implementing [`ConnectionInterface`](#connectioninterface): ```php $socket->on('connection', function (React\Socket\ConnectionInterface $connection) { echo 'Plaintext connection from ' . $connection->getRemoteAddress() . PHP_EOL; $connection->write('hello there!' . PHP_EOL); … }); ``` See also the [`ServerInterface`](#serverinterface) for more details. This class takes an optional `LoopInterface|null $loop` parameter that can be used to pass the event loop instance to use for this object. You can use a `null` value here in order to use the [default loop](https://github.com/reactphp/event-loop#loop). This value SHOULD NOT be given unless you're sure you want to explicitly use a given event loop instance. > Note that the `SocketServer` class is a concrete implementation for TCP/IP sockets. If you want to typehint in your higher-level protocol implementation, you SHOULD use the generic [`ServerInterface`](#serverinterface) instead. > Changelog v1.9.0: This class has been added with an improved constructor signature as a replacement for the previous `Server` class in order to avoid any ambiguities. The previous name has been deprecated and should not be used anymore. ### Advanced server usage #### TcpServer The `TcpServer` class implements the [`ServerInterface`](#serverinterface) and is responsible for accepting plaintext TCP/IP connections. ```php $server = new React\Socket\TcpServer(8080); ``` As above, the `$uri` parameter can consist of only a port, in which case the server will default to listening on the localhost address `127.0.0.1`, which means it will not be reachable from outside of this system. In order to use a random port assignment, you can use the port `0`: ```php $server = new React\Socket\TcpServer(0); $address = $server->getAddress(); ``` In order to change the host the socket is listening on, you can provide an IP address through the first parameter provided to the constructor, optionally preceded by the `tcp://` scheme: ```php $server = new React\Socket\TcpServer('192.168.0.1:8080'); ``` If you want to listen on an IPv6 address, you MUST enclose the host in square brackets: ```php $server = new React\Socket\TcpServer('[::1]:8080'); ``` If the given URI is invalid, does not contain a port, any other scheme or if it contains a hostname, it will throw an `InvalidArgumentException`: ```php // throws InvalidArgumentException due to missing port $server = new React\Socket\TcpServer('127.0.0.1'); ``` If the given URI appears to be valid, but listening on it fails (such as if port is already in use or port below 1024 may require root access etc.), it will throw a `RuntimeException`: ```php $first = new React\Socket\TcpServer(8080); // throws RuntimeException because port is already in use $second = new React\Socket\TcpServer(8080); ``` > Note that these error conditions may vary depending on your system and/or configuration. See the exception message and code for more details about the actual error condition. This class takes an optional `LoopInterface|null $loop` parameter that can be used to pass the event loop instance to use for this object. You can use a `null` value here in order to use the [default loop](https://github.com/reactphp/event-loop#loop). This value SHOULD NOT be given unless you're sure you want to explicitly use a given event loop instance. Optionally, you can specify [socket context options](https://www.php.net/manual/en/context.socket.php) for the underlying stream socket resource like this: ```php $server = new React\Socket\TcpServer('[::1]:8080', null, array( 'backlog' => 200, 'so_reuseport' => true, 'ipv6_v6only' => true )); ``` > Note that available [socket context options](https://www.php.net/manual/en/context.socket.php), their defaults and effects of changing these may vary depending on your system and/or PHP version. Passing unknown context options has no effect. The `backlog` context option defaults to `511` unless given explicitly. Whenever a client connects, it will emit a `connection` event with a connection instance implementing [`ConnectionInterface`](#connectioninterface): ```php $server->on('connection', function (React\Socket\ConnectionInterface $connection) { echo 'Plaintext connection from ' . $connection->getRemoteAddress() . PHP_EOL; $connection->write('hello there!' . PHP_EOL); … }); ``` See also the [`ServerInterface`](#serverinterface) for more details. #### SecureServer The `SecureServer` class implements the [`ServerInterface`](#serverinterface) and is responsible for providing a secure TLS (formerly known as SSL) server. It does so by wrapping a [`TcpServer`](#tcpserver) instance which waits for plaintext TCP/IP connections and then performs a TLS handshake for each connection. It thus requires valid [TLS context options](https://www.php.net/manual/en/context.ssl.php), which in its most basic form may look something like this if you're using a PEM encoded certificate file: ```php $server = new React\Socket\TcpServer(8000); $server = new React\Socket\SecureServer($server, null, array( 'local_cert' => 'server.pem' )); ``` > Note that the certificate file will not be loaded on instantiation but when an incoming connection initializes its TLS context. This implies that any invalid certificate file paths or contents will only cause an `error` event at a later time. If your private key is encrypted with a passphrase, you have to specify it like this: ```php $server = new React\Socket\TcpServer(8000); $server = new React\Socket\SecureServer($server, null, array( 'local_cert' => 'server.pem', 'passphrase' => 'secret' )); ``` By default, this server supports TLSv1.0+ and excludes support for legacy SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly choose the TLS version you want to negotiate with the remote side: ```php $server = new React\Socket\TcpServer(8000); $server = new React\Socket\SecureServer($server, null, array( 'local_cert' => 'server.pem', 'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_SERVER )); ``` > Note that available [TLS context options](https://www.php.net/manual/en/context.ssl.php), their defaults and effects of changing these may vary depending on your system and/or PHP version. Passing unknown context options has no effect. Whenever a client completes the TLS handshake, it will emit a `connection` event with a connection instance implementing [`ConnectionInterface`](#connectioninterface): ```php $server->on('connection', function (React\Socket\ConnectionInterface $connection) { echo 'Secure connection from' . $connection->getRemoteAddress() . PHP_EOL; $connection->write('hello there!' . PHP_EOL); … }); ``` Whenever a client fails to perform a successful TLS handshake, it will emit an `error` event and then close the underlying TCP/IP connection: ```php $server->on('error', function (Exception $e) { echo 'Error' . $e->getMessage() . PHP_EOL; }); ``` See also the [`ServerInterface`](#serverinterface) for more details. Note that the `SecureServer` class is a concrete implementation for TLS sockets. If you want to typehint in your higher-level protocol implementation, you SHOULD use the generic [`ServerInterface`](#serverinterface) instead. This class takes an optional `LoopInterface|null $loop` parameter that can be used to pass the event loop instance to use for this object. You can use a `null` value here in order to use the [default loop](https://github.com/reactphp/event-loop#loop). This value SHOULD NOT be given unless you're sure you want to explicitly use a given event loop instance. > Advanced usage: Despite allowing any `ServerInterface` as first parameter, you SHOULD pass a `TcpServer` instance as first parameter, unless you know what you're doing. Internally, the `SecureServer` has to set the required TLS context options on the underlying stream resources. These resources are not exposed through any of the interfaces defined in this package, but only through the internal `Connection` class. The `TcpServer` class is guaranteed to emit connections that implement the `ConnectionInterface` and uses the internal `Connection` class in order to expose these underlying resources. If you use a custom `ServerInterface` and its `connection` event does not meet this requirement, the `SecureServer` will emit an `error` event and then close the underlying connection. #### UnixServer The `UnixServer` class implements the [`ServerInterface`](#serverinterface) and is responsible for accepting connections on Unix domain sockets (UDS). ```php $server = new React\Socket\UnixServer('/tmp/server.sock'); ``` As above, the `$uri` parameter can consist of only a socket path or socket path prefixed by the `unix://` scheme. If the given URI appears to be valid, but listening on it fails (such as if the socket is already in use or the file not accessible etc.), it will throw a `RuntimeException`: ```php $first = new React\Socket\UnixServer('/tmp/same.sock'); // throws RuntimeException because socket is already in use $second = new React\Socket\UnixServer('/tmp/same.sock'); ``` > Note that these error conditions may vary depending on your system and/or configuration. In particular, Zend PHP does only report "Unknown error" when the UDS path already exists and can not be bound. You may want to check `is_file()` on the given UDS path to report a more user-friendly error message in this case. See the exception message and code for more details about the actual error condition. This class takes an optional `LoopInterface|null $loop` parameter that can be used to pass the event loop instance to use for this object. You can use a `null` value here in order to use the [default loop](https://github.com/reactphp/event-loop#loop). This value SHOULD NOT be given unless you're sure you want to explicitly use a given event loop instance. Whenever a client connects, it will emit a `connection` event with a connection instance implementing [`ConnectionInterface`](#connectioninterface): ```php $server->on('connection', function (React\Socket\ConnectionInterface $connection) { echo 'New connection' . PHP_EOL; $connection->write('hello there!' . PHP_EOL); … }); ``` See also the [`ServerInterface`](#serverinterface) for more details. #### LimitingServer The `LimitingServer` decorator wraps a given `ServerInterface` and is responsible for limiting and keeping track of open connections to this server instance. Whenever the underlying server emits a `connection` event, it will check its limits and then either - keep track of this connection by adding it to the list of open connections and then forward the `connection` event - or reject (close) the connection when its limits are exceeded and will forward an `error` event instead. Whenever a connection closes, it will remove this connection from the list of open connections. ```php $server = new React\Socket\LimitingServer($server, 100); $server->on('connection', function (React\Socket\ConnectionInterface $connection) { $connection->write('hello there!' . PHP_EOL); … }); ``` See also the [second example](examples) for more details. You have to pass a maximum number of open connections to ensure the server will automatically reject (close) connections once this limit is exceeded. In this case, it will emit an `error` event to inform about this and no `connection` event will be emitted. ```php $server = new React\Socket\LimitingServer($server, 100); $server->on('connection', function (React\Socket\ConnectionInterface $connection) { $connection->write('hello there!' . PHP_EOL); … }); ``` You MAY pass a `null` limit in order to put no limit on the number of open connections and keep accepting new connection until you run out of operating system resources (such as open file handles). This may be useful if you do not want to take care of applying a limit but still want to use the `getConnections()` method. You can optionally configure the server to pause accepting new connections once the connection limit is reached. In this case, it will pause the underlying server and no longer process any new connections at all, thus also no longer closing any excessive connections. The underlying operating system is responsible for keeping a backlog of pending connections until its limit is reached, at which point it will start rejecting further connections. Once the server is below the connection limit, it will continue consuming connections from the backlog and will process any outstanding data on each connection. This mode may be useful for some protocols that are designed to wait for a response message (such as HTTP), but may be less useful for other protocols that demand immediate responses (such as a "welcome" message in an interactive chat). ```php $server = new React\Socket\LimitingServer($server, 100, true); $server->on('connection', function (React\Socket\ConnectionInterface $connection) { $connection->write('hello there!' . PHP_EOL); … }); ``` ##### getConnections() The `getConnections(): ConnectionInterface[]` method can be used to return an array with all currently active connections. ```php foreach ($server->getConnection() as $connection) { $connection->write('Hi!'); } ``` ## Client usage ### ConnectorInterface The `ConnectorInterface` is responsible for providing an interface for establishing streaming connections, such as a normal TCP/IP connection. This is the main interface defined in this package and it is used throughout React's vast ecosystem. Most higher-level components (such as HTTP, database or other networking service clients) accept an instance implementing this interface to create their TCP/IP connection to the underlying networking service. This is usually done via dependency injection, so it's fairly simple to actually swap this implementation against any other implementation of this interface. The interface only offers a single method: #### connect() The `connect(string $uri): PromiseInterface<ConnectionInterface,Exception>` method can be used to create a streaming connection to the given remote address. It returns a [Promise](https://github.com/reactphp/promise) which either fulfills with a stream implementing [`ConnectionInterface`](#connectioninterface) on success or rejects with an `Exception` if the connection is not successful: ```php $connector->connect('google.com:443')->then( function (React\Socket\ConnectionInterface $connection) { // connection successfully established }, function (Exception $error) { // failed to connect due to $error } ); ``` See also [`ConnectionInterface`](#connectioninterface) for more details. The returned Promise MUST be implemented in such a way that it can be cancelled when it is still pending. Cancelling a pending promise MUST reject its value with an `Exception`. It SHOULD clean up any underlying resources and references as applicable: ```php $promise = $connector->connect($uri); $promise->cancel(); ``` ### Connector The `Connector` class is the main class in this package that implements the [`ConnectorInterface`](#connectorinterface) and allows you to create streaming connections. You can use this connector to create any kind of streaming connections, such as plaintext TCP/IP, secure TLS or local Unix connection streams. It binds to the main event loop and can be used like this: ```php $connector = new React\Socket\Connector(); $connector->connect($uri)->then(function (React\Socket\ConnectionInterface $connection) { $connection->write('...'); $connection->end(); }, function (Exception $e) { echo 'Error: ' . $e->getMessage() . PHP_EOL; }); ``` In order to create a plaintext TCP/IP connection, you can simply pass a host and port combination like this: ```php $connector->connect('www.google.com:80')->then(function (React\Socket\ConnectionInterface $connection) { $connection->write('...'); $connection->end(); }); ``` > If you do no specify a URI scheme in the destination URI, it will assume `tcp://` as a default and establish a plaintext TCP/IP connection. Note that TCP/IP connections require a host and port part in the destination URI like above, all other URI components are optional. In order to create a secure TLS connection, you can use the `tls://` URI scheme like this: ```php $connector->connect('tls://www.google.com:443')->then(function (React\Socket\ConnectionInterface $connection) { $connection->write('...'); $connection->end(); }); ``` In order to create a local Unix domain socket connection, you can use the `unix://` URI scheme like this: ```php $connector->connect('unix:///tmp/demo.sock')->then(function (React\Socket\ConnectionInterface $connection) { $connection->write('...'); $connection->end(); }); ``` > The [`getRemoteAddress()`](#getremoteaddress) method will return the target Unix domain socket (UDS) path as given to the `connect()` method, including the `unix://` scheme, for example `unix:///tmp/demo.sock`. The [`getLocalAddress()`](#getlocaladdress) method will most likely return a `null` value as this value is not applicable to UDS connections here. Under the hood, the `Connector` is implemented as a *higher-level facade* for the lower-level connectors implemented in this package. This means it also shares all of their features and implementation details. If you want to typehint in your higher-level protocol implementation, you SHOULD use the generic [`ConnectorInterface`](#connectorinterface) instead. As of `v1.4.0`, the `Connector` class defaults to using the [happy eyeballs algorithm](https://en.wikipedia.org/wiki/Happy_Eyeballs) to automatically connect over IPv4 or IPv6 when a hostname is given. This automatically attempts to connect using both IPv4 and IPv6 at the same time (preferring IPv6), thus avoiding the usual problems faced by users with imperfect IPv6 connections or setups. If you want to revert to the old behavior of only doing an IPv4 lookup and only attempt a single IPv4 connection, you can set up the `Connector` like this: ```php $connector = new React\Socket\Connector(array( 'happy_eyeballs' => false )); ``` Similarly, you can also affect the default DNS behavior as follows. The `Connector` class will try to detect your system DNS settings (and uses Google's public DNS server `8.8.8.8` as a fallback if unable to determine your system settings) to resolve all public hostnames into underlying IP addresses by default. If you explicitly want to use a custom DNS server (such as a local DNS relay or a company wide DNS server), you can set up the `Connector` like this: ```php $connector = new React\Socket\Connector(array( 'dns' => '127.0.1.1' )); $connector->connect('localhost:80')->then(function (React\Socket\ConnectionInterface $connection) { $connection->write('...'); $connection->end(); }); ``` If you do not want to use a DNS resolver at all and want to connect to IP addresses only, you can also set up your `Connector` like this: ```php $connector = new React\Socket\Connector(array( 'dns' => false )); $connector->connect('127.0.0.1:80')->then(function (React\Socket\ConnectionInterface $connection) { $connection->write('...'); $connection->end(); }); ``` Advanced: If you need a custom DNS `React\Dns\Resolver\ResolverInterface` instance, you can also set up your `Connector` like this: ```php $dnsResolverFactory = new React\Dns\Resolver\Factory(); $resolver = $dnsResolverFactory->createCached('127.0.1.1'); $connector = new React\Socket\Connector(array( 'dns' => $resolver )); $connector->connect('localhost:80')->then(function (React\Socket\ConnectionInterface $connection) { $connection->write('...'); $connection->end(); }); ``` By default, the `tcp://` and `tls://` URI schemes will use timeout value that respects your `default_socket_timeout` ini setting (which defaults to 60s). If you want a custom timeout value, you can simply pass this like this: ```php $connector = new React\Socket\Connector(array( 'timeout' => 10.0 )); ``` Similarly, if you do not want to apply a timeout at all and let the operating system handle this, you can pass a boolean flag like this: ```php $connector = new React\Socket\Connector(array( 'timeout' => false )); ``` By default, the `Connector` supports the `tcp://`, `tls://` and `unix://` URI schemes. If you want to explicitly prohibit any of these, you can simply pass boolean flags like this: ```php // only allow secure TLS connections $connector = new React\Socket\Connector(array( 'tcp' => false, 'tls' => true, 'unix' => false, )); $connector->connect('tls://google.com:443')->then(function (React\Socket\ConnectionInterface $connection) { $connection->write('...'); $connection->end(); }); ``` The `tcp://` and `tls://` also accept additional context options passed to the underlying connectors. If you want to explicitly pass additional context options, you can simply pass arrays of context options like this: ```php // allow insecure TLS connections $connector = new React\Socket\Connector(array( 'tcp' => array( 'bindto' => '192.168.0.1:0' ), 'tls' => array( 'verify_peer' => false, 'verify_peer_name' => false ), )); $connector->connect('tls://localhost:443')->then(function (React\Socket\ConnectionInterface $connection) { $connection->write('...'); $connection->end(); }); ``` By default, this connector supports TLSv1.0+ and excludes support for legacy SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly choose the TLS version you want to negotiate with the remote side: ```php $connector = new React\Socket\Connector(array( 'tls' => array( 'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT ) )); ``` > For more details about context options, please refer to the PHP documentation about [socket context options](https://www.php.net/manual/en/context.socket.php) and [SSL context options](https://www.php.net/manual/en/context.ssl.php). Advanced: By default, the `Connector` supports the `tcp://`, `tls://` and `unix://` URI schemes. For this, it sets up the required connector classes automatically. If you want to explicitly pass custom connectors for any of these, you can simply pass an instance implementing the `ConnectorInterface` like this: ```php $dnsResolverFactory = new React\Dns\Resolver\Factory(); $resolver = $dnsResolverFactory->createCached('127.0.1.1'); $tcp = new React\Socket\HappyEyeBallsConnector(null, new React\Socket\TcpConnector(), $resolver); $tls = new React\Socket\SecureConnector($tcp); $unix = new React\Socket\UnixConnector(); $connector = new React\Socket\Connector(array( 'tcp' => $tcp, 'tls' => $tls, 'unix' => $unix, 'dns' => false, 'timeout' => false, )); $connector->connect('google.com:80')->then(function (React\Socket\ConnectionInterface $connection) { $connection->write('...'); $connection->end(); }); ``` > Internally, the `tcp://` connector will always be wrapped by the DNS resolver, unless you disable DNS like in the above example. In this case, the `tcp://` connector receives the actual hostname instead of only the resolved IP address and is thus responsible for performing the lookup. Internally, the automatically created `tls://` connector will always wrap the underlying `tcp://` connector for establishing the underlying plaintext TCP/IP connection before enabling secure TLS mode. If you want to use a custom underlying `tcp://` connector for secure TLS connections only, you may explicitly pass a `tls://` connector like above instead. Internally, the `tcp://` and `tls://` connectors will always be wrapped by `TimeoutConnector`, unless you disable timeouts like in the above example. This class takes an optional `LoopInterface|null $loop` parameter that can be used to pass the event loop instance to use for this object. You can use a `null` value here in order to use the [default loop](https://github.com/reactphp/event-loop#loop). This value SHOULD NOT be given unless you're sure you want to explicitly use a given event loop instance. > Changelog v1.9.0: The constructur signature has been updated to take the > optional `$context` as the first parameter and the optional `$loop` as a second > argument. The previous signature has been deprecated and should not be used anymore. > > ```php > // constructor signature as of v1.9.0 > $connector = new React\Socket\Connector(array $context = [], ?LoopInterface $loop = null); > > // legacy constructor signature before v1.9.0 > $connector = new React\Socket\Connector(?LoopInterface $loop = null, array $context = []); > ``` ### Advanced client usage #### TcpConnector The `TcpConnector` class implements the [`ConnectorInterface`](#connectorinterface) and allows you to create plaintext TCP/IP connections to any IP-port-combination: ```php $tcpConnector = new React\Socket\TcpConnector(); $tcpConnector->connect('127.0.0.1:80')->then(function (React\Socket\ConnectionInterface $connection) { $connection->write('...'); $connection->end(); }); ``` See also the [examples](examples). Pending connection attempts can be cancelled by cancelling its pending promise like so: ```php $promise = $tcpConnector->connect('127.0.0.1:80'); $promise->cancel(); ``` Calling `cancel()` on a pending promise will close the underlying socket resource, thus cancelling the pending TCP/IP connection, and reject the resulting promise. This class takes an optional `LoopInterface|null $loop` parameter that can be used to pass the event loop instance to use for this object. You can use a `null` value here in order to use the [default loop](https://github.com/reactphp/event-loop#loop). This value SHOULD NOT be given unless you're sure you want to explicitly use a given event loop instance. You can optionally pass additional [socket context options](https://www.php.net/manual/en/context.socket.php) to the constructor like this: ```php $tcpConnector = new React\Socket\TcpConnector(null, array( 'bindto' => '192.168.0.1:0' )); ``` Note that this class only allows you to connect to IP-port-combinations. If the given URI is invalid, does not contain a valid IP address and port or contains any other scheme, it will reject with an `InvalidArgumentException`: If the given URI appears to be valid, but connecting to it fails (such as if the remote host rejects the connection etc.), it will reject with a `RuntimeException`. If you want to connect to hostname-port-combinations, see also the following chapter. > Advanced usage: Internally, the `TcpConnector` allocates an empty *context* resource for each stream resource. If the destination URI contains a `hostname` query parameter, its value will be used to set up the TLS peer name. This is used by the `SecureConnector` and `DnsConnector` to verify the peer name and can also be used if you want a custom TLS peer name. #### HappyEyeBallsConnector The `HappyEyeBallsConnector` class implements the [`ConnectorInterface`](#connectorinterface) and allows you to create plaintext TCP/IP connections to any hostname-port-combination. Internally it implements the happy eyeballs algorithm from [`RFC6555`](https://tools.ietf.org/html/rfc6555) and [`RFC8305`](https://tools.ietf.org/html/rfc8305) to support IPv6 and IPv4 hostnames. It does so by decorating a given `TcpConnector` instance so that it first looks up the given domain name via DNS (if applicable) and then establishes the underlying TCP/IP connection to the resolved target IP address. Make sure to set up your DNS resolver and underlying TCP connector like this: ```php $dnsResolverFactory = new React\Dns\Resolver\Factory(); $dns = $dnsResolverFactory->createCached('8.8.8.8'); $dnsConnector = new React\Socket\HappyEyeBallsConnector(null, $tcpConnector, $dns); $dnsConnector->connect('www.google.com:80')->then(function (React\Socket\ConnectionInterface $connection) { $connection->write('...'); $connection->end(); }); ``` See also the [examples](examples). Pending connection attempts can be cancelled by cancelling its pending promise like so: ```php $promise = $dnsConnector->connect('www.google.com:80'); $promise->cancel(); ``` Calling `cancel()` on a pending promise will cancel the underlying DNS lookups and/or the underlying TCP/IP connection(s) and reject the resulting promise. This class takes an optional `LoopInterface|null $loop` parameter that can be used to pass the event loop instance to use for this object. You can use a `null` value here in order to use the [default loop](https://github.com/reactphp/event-loop#loop). This value SHOULD NOT be given unless you're sure you want to explicitly use a given event loop instance. > Advanced usage: Internally, the `HappyEyeBallsConnector` relies on a `Resolver` to look up the IP addresses for the given hostname. It will then replace the hostname in the destination URI with this IP's and append a `hostname` query parameter and pass this updated URI to the underlying connector. The Happy Eye Balls algorithm describes looking the IPv6 and IPv4 address for the given hostname so this connector sends out two DNS lookups for the A and AAAA records. It then uses all IP addresses (both v6 and v4) and tries to connect to all of them with a 50ms interval in between. Alterating between IPv6 and IPv4 addresses. When a connection is established all the other DNS lookups and connection attempts are cancelled. #### DnsConnector The `DnsConnector` class implements the [`ConnectorInterface`](#connectorinterface) and allows you to create plaintext TCP/IP connections to any hostname-port-combination. It does so by decorating a given `TcpConnector` instance so that it first looks up the given domain name via DNS (if applicable) and then establishes the underlying TCP/IP connection to the resolved target IP address. Make sure to set up your DNS resolver and underlying TCP connector like this: ```php $dnsResolverFactory = new React\Dns\Resolver\Factory(); $dns = $dnsResolverFactory->createCached('8.8.8.8'); $dnsConnector = new React\Socket\DnsConnector($tcpConnector, $dns); $dnsConnector->connect('www.google.com:80')->then(function (React\Socket\ConnectionInterface $connection) { $connection->write('...'); $connection->end(); }); ``` See also the [examples](examples). Pending connection attempts can be cancelled by cancelling its pending promise like so: ```php $promise = $dnsConnector->connect('www.google.com:80'); $promise->cancel(); ``` Calling `cancel()` on a pending promise will cancel the underlying DNS lookup and/or the underlying TCP/IP connection and reject the resulting promise. > Advanced usage: Internally, the `DnsConnector` relies on a `React\Dns\Resolver\ResolverInterface` to look up the IP address for the given hostname. It will then replace the hostname in the destination URI with this IP and append a `hostname` query parameter and pass this updated URI to the underlying connector. The underlying connector is thus responsible for creating a connection to the target IP address, while this query parameter can be used to check the original hostname and is used by the `TcpConnector` to set up the TLS peer name. If a `hostname` is given explicitly, this query parameter will not be modified, which can be useful if you want a custom TLS peer name. #### SecureConnector The `SecureConnector` class implements the [`ConnectorInterface`](#connectorinterface) and allows you to create secure TLS (formerly known as SSL) connections to any hostname-port-combination. It does so by decorating a given `DnsConnector` instance so that it first creates a plaintext TCP/IP connection and then enables TLS encryption on this stream. ```php $secureConnector = new React\Socket\SecureConnector($dnsConnector); $secureConnector->connect('www.google.com:443')->then(function (React\Socket\ConnectionInterface $connection) { $connection->write("GET / HTTP/1.0\r\nHost: www.google.com\r\n\r\n"); ... }); ``` See also the [examples](examples). Pending connection attempts can be cancelled by cancelling its pending promise like so: ```php $promise = $secureConnector->connect('www.google.com:443'); $promise->cancel(); ``` Calling `cancel()` on a pending promise will cancel the underlying TCP/IP connection and/or the SSL/TLS negotiation and reject the resulting promise. This class takes an optional `LoopInterface|null $loop` parameter that can be used to pass the event loop instance to use for this object. You can use a `null` value here in order to use the [default loop](https://github.com/reactphp/event-loop#loop). This value SHOULD NOT be given unless you're sure you want to explicitly use a given event loop instance. You can optionally pass additional [SSL context options](https://www.php.net/manual/en/context.ssl.php) to the constructor like this: ```php $secureConnector = new React\Socket\SecureConnector($dnsConnector, null, array( 'verify_peer' => false, 'verify_peer_name' => false )); ``` By default, this connector supports TLSv1.0+ and excludes support for legacy SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly choose the TLS version you want to negotiate with the remote side: ```php $secureConnector = new React\Socket\SecureConnector($dnsConnector, null, array( 'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT )); ``` > Advanced usage: Internally, the `SecureConnector` relies on setting up the required *context options* on the underlying stream resource. It should therefor be used with a `TcpConnector` somewhere in the connector stack so that it can allocate an empty *context* resource for each stream resource and verify the peer name. Failing to do so may result in a TLS peer name mismatch error or some hard to trace race conditions, because all stream resources will use a single, shared *default context* resource otherwise. #### TimeoutConnector The `TimeoutConnector` class implements the [`ConnectorInterface`](#connectorinterface) and allows you to add timeout handling to any existing connector instance. It does so by decorating any given [`ConnectorInterface`](#connectorinterface) instance and starting a timer that will automatically reject and abort any underlying connection attempt if it takes too long. ```php $timeoutConnector = new React\Socket\TimeoutConnector($connector, 3.0); $timeoutConnector->connect('google.com:80')->then(function (React\Socket\ConnectionInterface $connection) { // connection succeeded within 3.0 seconds }); ``` See also any of the [examples](examples). This class takes an optional `LoopInterface|null $loop` parameter that can be used to pass the event loop instance to use for this object. You can use a `null` value here in order to use the [default loop](https://github.com/reactphp/event-loop#loop). This value SHOULD NOT be given unless you're sure you want to explicitly use a given event loop instance. Pending connection attempts can be cancelled by cancelling its pending promise like so: ```php $promise = $timeoutConnector->connect('google.com:80'); $promise->cancel(); ``` Calling `cancel()` on a pending promise will cancel the underlying connection attempt, abort the timer and reject the resulting promise. #### UnixConnector The `UnixConnector` class implements the [`ConnectorInterface`](#connectorinterface) and allows you to connect to Unix domain socket (UDS) paths like this: ```php $connector = new React\Socket\UnixConnector(); $connector->connect('/tmp/demo.sock')->then(function (React\Socket\ConnectionInterface $connection) { $connection->write("HELLO\n"); }); ``` Connecting to Unix domain sockets is an atomic operation, i.e. its promise will settle (either resolve or reject) immediately. As such, calling `cancel()` on the resulting promise has no effect. > The [`getRemoteAddress()`](#getremoteaddress) method will return the target Unix domain socket (UDS) path as given to the `connect()` method, prepended with the `unix://` scheme, for example `unix:///tmp/demo.sock`. The [`getLocalAddress()`](#getlocaladdress) method will most likely return a `null` value as this value is not applicable to UDS connections here. This class takes an optional `LoopInterface|null $loop` parameter that can be used to pass the event loop instance to use for this object. You can use a `null` value here in order to use the [default loop](https://github.com/reactphp/event-loop#loop). This value SHOULD NOT be given unless you're sure you want to explicitly use a given event loop instance. #### FixedUriConnector The `FixedUriConnector` class implements the [`ConnectorInterface`](#connectorinterface) and decorates an existing Connector to always use a fixed, preconfigured URI. This can be useful for consumers that do not support certain URIs, such as when you want to explicitly connect to a Unix domain socket (UDS) path instead of connecting to a default address assumed by an higher-level API: ```php $connector = new React\Socket\FixedUriConnector( 'unix:///var/run/docker.sock', new React\Socket\UnixConnector() ); // destination will be ignored, actually connects to Unix domain socket $promise = $connector->connect('localhost:80'); ``` ## Install The recommended way to install this library is [through Composer](https://getcomposer.org/). [New to Composer?](https://getcomposer.org/doc/00-intro.md) This project follows [SemVer](https://semver.org/). This will install the latest supported version: ```bash $ composer require react/socket:^1.10 ``` See also the [CHANGELOG](CHANGELOG.md) for details about version upgrades. This project aims to run on any platform and thus does not require any PHP extensions and supports running on legacy PHP 5.3 through current PHP 8+ and HHVM. It's *highly recommended to use the latest supported PHP version* for this project, partly due to its vast performance improvements and partly because legacy PHP versions require several workarounds as described below. Secure TLS connections received some major upgrades starting with PHP 5.6, with the defaults now being more secure, while older versions required explicit context options. This library does not take responsibility over these context options, so it's up to consumers of this library to take care of setting appropriate context options as described above. PHP < 7.3.3 (and PHP < 7.2.15) suffers from a bug where feof() might block with 100% CPU usage on fragmented TLS records. We try to work around this by always consuming the complete receive buffer at once to avoid stale data in TLS buffers. This is known to work around high CPU usage for well-behaving peers, but this may cause very large data chunks for high throughput scenarios. The buggy behavior can still be triggered due to network I/O buffers or malicious peers on affected versions, upgrading is highly recommended. PHP < 7.1.4 (and PHP < 7.0.18) suffers from a bug when writing big chunks of data over TLS streams at once. We try to work around this by limiting the write chunk size to 8192 bytes for older PHP versions only. This is only a work-around and has a noticable performance penalty on affected versions. This project also supports running on HHVM. Note that really old HHVM < 3.8 does not support secure TLS connections, as it lacks the required `stream_socket_enable_crypto()` function. As such, trying to create a secure TLS connections on affected versions will return a rejected promise instead. This issue is also covered by our test suite, which will skip related tests on affected versions. ## Tests To run the test suite, you first need to clone this repo and then install all dependencies [through Composer](https://getcomposer.org/): ```bash $ composer install ``` To run the test suite, go to the project root and run: ```bash $ vendor/bin/phpunit ``` The test suite also contains a number of functional integration tests that rely on a stable internet connection. If you do not want to run these, they can simply be skipped like this: ```bash $ vendor/bin/phpunit --exclude-group internet ``` ## License MIT, see [LICENSE file](LICENSE).

All functions reside under the `React\Promise\Timer` namespace. The below examples refer to all functions with their fully-qualified names like this: ```php React\Promise\Timer\timeout(…); ``` As of PHP 5.6+ you can also import each required function into your code like this: ```php use function React\Promise\Timer\timeout; timeout(…); ``` Alternatively, you can also use an import statement similar to this: ```php use React\Promise\Timer; Timer\timeout(…); ``` ### timeout() The `timeout(PromiseInterface<mixed, Exception|mixed> $promise, float $time, ?LoopInterface $loop = null): PromiseInterface<mixed, TimeoutException|Exception|mixed>` function can be used to cancel operations that take *too long*. You need to pass in an input `$promise` that represents a pending operation and timeout parameters. It returns a new promise with the following resolution behavior: - If the input `$promise` resolves before `$time` seconds, resolve the resulting promise with its fulfillment value. - If the input `$promise` rejects before `$time` seconds, reject the resulting promise with its rejection value. - If the input `$promise` does not settle before `$time` seconds, *cancel* the operation and reject the resulting promise with a [`TimeoutException`](#timeoutexception). Internally, the given `$time` value will be used to start a timer that will *cancel* the pending operation once it triggers. This implies that if you pass a really small (or negative) value, it will still start a timer and will thus trigger at the earliest possible time in the future. If the input `$promise` is already settled, then the resulting promise will resolve or reject immediately without starting a timer at all. This function takes an optional `LoopInterface|null $loop` parameter that can be used to pass the event loop instance to use. You can use a `null` value here in order to use the [default loop](https://github.com/reactphp/event-loop#loop). This value SHOULD NOT be given unless you're sure you want to explicitly use a given event loop instance. A common use case for handling only resolved values looks like this: ```php $promise = accessSomeRemoteResource(); React\Promise\Timer\timeout($promise, 10.0)->then(function ($value) { // the operation finished within 10.0 seconds }); ``` A more complete example could look like this: ```php $promise = accessSomeRemoteResource(); React\Promise\Timer\timeout($promise, 10.0)->then( function ($value) { // the operation finished within 10.0 seconds }, function ($error) { if ($error instanceof React\Promise\Timer\TimeoutException) { // the operation has failed due to a timeout } else { // the input operation has failed due to some other error } } ); ``` Or if you're using [react/promise v2.2.0](https://github.com/reactphp/promise) or up: ```php React\Promise\Timer\timeout($promise, 10.0) ->then(function ($value) { // the operation finished within 10.0 seconds }) ->otherwise(function (React\Promise\Timer\TimeoutException $error) { // the operation has failed due to a timeout }) ->otherwise(function ($error) { // the input operation has failed due to some other error }) ; ``` As discussed above, the [`timeout()`](#timeout) function will take care of the underlying operation if it takes *too long*. In this case, you can be sure the resulting promise will always be rejected with a [`TimeoutException`](#timeoutexception). On top of this, the function will try to *cancel* the underlying operation. Responsibility for this cancellation logic is left up to the underlying operation. - A common use case involves cleaning up any resources like open network sockets or file handles or terminating external processes or timers. - If the given input `$promise` does not support cancellation, then this is a NO-OP. This means that while the resulting promise will still be rejected, the underlying input `$promise` may still be pending and can hence continue consuming resources On top of this, the returned promise is implemented in such a way that it can be cancelled when it is still pending. Cancelling a pending promise will cancel the underlying operation. As discussed above, responsibility for this cancellation logic is left up to the underlying operation. ```php $promise = accessSomeRemoteResource(); $timeout = React\Promise\Timer\timeout($promise, 10.0); $timeout->cancel(); ``` For more details on the promise cancellation, please refer to the [Promise documentation](https://github.com/reactphp/promise#cancellablepromiseinterface). If you want to wait for multiple promises to resolve, you can use the normal promise primitives like this: ```php $promises = array( accessSomeRemoteResource(), accessSomeRemoteResource(), accessSomeRemoteResource() ); $promise = React\Promise\all($promises); React\Promise\Timer\timeout($promise, 10)->then(function ($values) { // *all* promises resolved }); ``` The applies to all promise collection primitives alike, i.e. `all()`, `race()`, `any()`, `some()` etc. For more details on the promise primitives, please refer to the [Promise documentation](https://github.com/reactphp/promise#functions). ### sleep() The `sleep(float $time, ?LoopInterface $loop = null): PromiseInterface<void, RuntimeException>` function can be used to create a new promise that resolves in `$time` seconds. ```php React\Promise\Timer\sleep(1.5)->then(function () { echo 'Thanks for waiting!' . PHP_EOL; }); ``` Internally, the given `$time` value will be used to start a timer that will resolve the promise once it triggers. This implies that if you pass a really small (or negative) value, it will still start a timer and will thus trigger at the earliest possible time in the future. This function takes an optional `LoopInterface|null $loop` parameter that can be used to pass the event loop instance to use. You can use a `null` value here in order to use the [default loop](https://github.com/reactphp/event-loop#loop). This value SHOULD NOT be given unless you're sure you want to explicitly use a given event loop instance. The returned promise is implemented in such a way that it can be cancelled when it is still pending. Cancelling a pending promise will reject its value with a `RuntimeException` and clean up any pending timers. ```php $timer = React\Promise\Timer\sleep(2.0); $timer->cancel(); ``` ### ~~resolve()~~ > Deprecated since v1.8.0, see [`sleep()`](#sleep) instead. The `resolve(float $time, ?LoopInterface $loop = null): PromiseInterface<float, RuntimeException>` function can be used to create a new promise that resolves in `$time` seconds with the `$time` as the fulfillment value. ```php React\Promise\Timer\resolve(1.5)->then(function ($time) { echo 'Thanks for waiting ' . $time . ' seconds' . PHP_EOL; }); ``` Internally, the given `$time` value will be used to start a timer that will resolve the promise once it triggers. This implies that if you pass a really small (or negative) value, it will still start a timer and will thus trigger at the earliest possible time in the future. This function takes an optional `LoopInterface|null $loop` parameter that can be used to pass the event loop instance to use. You can use a `null` value here in order to use the [default loop](https://github.com/reactphp/event-loop#loop). This value SHOULD NOT be given unless you're sure you want to explicitly use a given event loop instance. The returned promise is implemented in such a way that it can be cancelled when it is still pending. Cancelling a pending promise will reject its value with a `RuntimeException` and clean up any pending timers. ```php $timer = React\Promise\Timer\resolve(2.0); $timer->cancel(); ``` ### ~~reject()~~ > Deprecated since v1.8.0, see [`sleep()`](#sleep) instead. The `reject(float $time, ?LoopInterface $loop = null): PromiseInterface<void, TimeoutException|RuntimeException>` function can be used to create a new promise which rejects in `$time` seconds with a `TimeoutException`. ```php React\Promise\Timer\reject(2.0)->then(null, function (React\Promise\Timer\TimeoutException $e) { echo 'Rejected after ' . $e->getTimeout() . ' seconds ' . PHP_EOL; }); ``` Internally, the given `$time` value will be used to start a timer that will reject the promise once it triggers. This implies that if you pass a really small (or negative) value, it will still start a timer and will thus trigger at the earliest possible time in the future. This function takes an optional `LoopInterface|null $loop` parameter that can be used to pass the event loop instance to use. You can use a `null` value here in order to use the [default loop](https://github.com/reactphp/event-loop#loop). This value SHOULD NOT be given unless you're sure you want to explicitly use a given event loop instance. The returned promise is implemented in such a way that it can be cancelled when it is still pending. Cancelling a pending promise will reject its value with a `RuntimeException` and clean up any pending timers. ```php $timer = React\Promise\Timer\reject(2.0); $timer->cancel(); ``` ### TimeoutException The `TimeoutException` extends PHP's built-in `RuntimeException`. #### getTimeout() The `getTimeout(): float` method can be used to get the timeout value in seconds. ## Install The recommended way to install this library is [through Composer](https://getcomposer.org/).

We'd like to emphasize that this component is production ready and battle-tested. We plan to support all long-term support (LTS) releases for at least 24 months, so you have a rock-solid foundation to build on top of. > Contains no other changes, so it's actually fully compatible with the v0.7.7 release. ## 0.7.7 (2018-01-19) * Improve test suite by fixing forward compatibility with upcoming EventLoop releases, avoid risky tests and add test group to skip integration tests relying on internet connection and apply appropriate test timeouts.

(#96 and #103 by @clue) If either side of the composite stream closes, it will also close the other side. We now also ensure that if either side is already closed during instantiation, it will also close the other side. * BC break: Mark all classes as `final` and mark internal API as `private` to discourage inheritance (#95 and #99 by @clue) * Feature / BC break: Only emit `error` event for fatal errors (#92 by @clue) > The `error` event was previously also allowed to be emitted for non-fatal errors, but our implementations actually only ever emitted this as a fatal error and then closed the stream. * Feature: Explicitly allow custom events and exclude any semantics (#97 by @clue) * Strict definition for event callback functions (#101 by @clue) * Support legacy PHP 5.3 through PHP 7.1 and HHVM and improve usage documentation (#100 and #102 by @clue) * Actually require all dependencies so this is self-contained and improve forward compatibility with EventLoop v1.0 and v0.5 (#94 and #98 by @clue) ## 0.6.0 (2017-03-26) * Feature / Fix / BC break: Add `DuplexResourceStream` and deprecate `Stream` (#85 by @clue) ```php // old (does still work for BC reasons) $stream = new Stream($connection, $loop); // new $stream = new DuplexResourceStream($connection, $loop); ``` Note that the `DuplexResourceStream` now rejects read-only or write-only streams, so this may affect BC. If you want a read-only or write-only resource, use `ReadableResourceStream` or `WritableResourceStream` instead of `DuplexResourceStream`. > BC note: This class was previously called `Stream`. The `Stream` class still exists for BC reasons and will be removed in future versions of this package. * Feature / BC break: Add `WritableResourceStream` (previously called `Buffer`) (#84 by @clue) ```php // old $stream = new Buffer(STDOUT, $loop); // new $stream = new WritableResourceStream(STDOUT, $loop); ``` * Feature: Add `ReadableResourceStream` (#83 by @clue) ```php $stream = new ReadableResourceStream(STDIN, $loop); ``` * Fix / BC Break: Enforce using non-blocking I/O (#46 by @clue) > BC note: This is known to affect process pipes on Windows which do not support non-blocking I/O and could thus block the whole EventLoop previously. * Feature / Fix / BC break: Consistent semantics for `DuplexStreamInterface::end()` to ensure it SHOULD also end readable side (#86 by @clue) * Fix: Do not use unbuffered reads on pipe streams for legacy PHP < 5.4 (#80 by @clue) ## 0.5.0 (2017-03-08) * Feature / BC break: Consistent `end` event semantics (EOF) (#70 by @clue) The `end` event will now only be emitted for a *successful* end, not if the stream closes due to an unrecoverable `error` event or if you call `close()` explicitly. If you want to detect when the stream closes (terminates), use the `close` event instead. * BC break: Remove custom (undocumented) `full-drain` event from `Buffer` (#63 and #68 by @clue) > The `full-drain` event was undocumented and mostly used internally. Relying on this event has attracted some low-quality code in the past, so we've removed this from the public API in order to work out a better solution instead. If you want to detect when the buffer finishes flushing data to the stream, you may want to look into its `end()` method or the `close` event instead. * Feature / BC break: Consistent event semantics and documentation, explicitly state *when* events will be emitted and *which* arguments they receive. (#73 and #69 by @clue) The documentation now explicitly defines each event and its arguments. Custom events and event arguments are still supported. Most notably, all defined events only receive inherently required event arguments and no longer transmit the instance they are emitted on for consistency and performance reasons. ```php // old (inconsistent and not supported by all implementations) $stream->on('data', function ($data, $stream) { // process $data }); // new (consistent throughout the whole ecosystem) $stream->on('data', function ($data) use ($stream) { // process $data }); ``` > This mostly adds documentation (and thus some stricter, consistent definitions) for the existing behavior, it does NOT define any major changes otherwise. Most existing code should be compatible with these changes, unless it relied on some undocumented/unintended semantics. * Feature / BC break: Consistent method semantics and documentation (#72 by @clue) > This mostly adds documentation (and thus some stricter, consistent definitions) for the existing behavior, it does NOT define any major changes otherwise. Most existing code should be compatible with these changes, unless it relied on some undocumented/unintended semantics. * Feature: Consistent `pipe()` semantics for closed and closing streams (#71 from @clue) The source stream will now always be paused via `pause()` when the destination stream closes. Also, properly stop piping if the source stream closes and remove all event forwarding. * Improve test suite by adding PHPUnit to `require-dev` and improving coverage.

In order to make the [EventLoop](https://github.com/reactphp/event-loop) easier to use, this component introduces the powerful concept of "streams". Streams allow you to efficiently process huge amounts of data (such as a multi Gigabyte file download) in small chunks without having to store everything in memory at once. They are very similar to the streams found in PHP itself, but have an interface more suited for async, non-blocking I/O. **Table of contents** * [Stream usage](#stream-usage) * [ReadableStreamInterface](#readablestreaminterface) * [data event](#data-event) * [end event](#end-event) * [error event](#error-event) * [close event](#close-event) * [isReadable()](#isreadable) * [pause()](#pause) * [resume()](#resume) * [pipe()](#pipe) * [close()](#close) * [WritableStreamInterface](#writablestreaminterface) * [drain event](#drain-event) * [pipe event](#pipe-event) * [error event](#error-event-1) * [close event](#close-event-1) * [isWritable()](#iswritable) * [write()](#write) * [end()](#end) * [close()](#close-1) * [DuplexStreamInterface](#duplexstreaminterface) * [Creating streams](#creating-streams) * [ReadableResourceStream](#readableresourcestream) * [WritableResourceStream](#writableresourcestream) * [DuplexResourceStream](#duplexresourcestream) * [ThroughStream](#throughstream) * [CompositeStream](#compositestream) * [Usage](#usage) * [Install](#install) * [Tests](#tests) * [License](#license) * [More](#more) ## Stream usage ReactPHP uses the concept of "streams" throughout its ecosystem to provide a consistent higher-level abstraction for processing streams of arbitrary data contents and size. While a stream itself is a quite low-level concept, it can be used as a powerful abstraction to build higher-level components and protocols on top. If you're new to this concept, it helps to think of them as a water pipe: You can consume water from a source or you can produce water and forward (pipe) it to any destination (sink). Similarly, streams can either be * readable (such as `STDIN` terminal input) or * writable (such as `STDOUT` terminal output) or * duplex (both readable *and* writable, such as a TCP/IP connection) Accordingly, this package defines the following three interfaces * [`ReadableStreamInterface`](#readablestreaminterface) * [`WritableStreamInterface`](#writablestreaminterface) * [`DuplexStreamInterface`](#duplexstreaminterface) ### ReadableStreamInterface The `ReadableStreamInterface` is responsible for providing an interface for read-only streams and the readable side of duplex streams. Besides defining a few methods, this interface also implements the `EventEmitterInterface` which allows you to react to certain events. The event callback functions MUST be a valid `callable` that obeys strict parameter definitions and MUST accept event parameters exactly as documented. The event callback functions MUST NOT throw an `Exception`. The return value of the event callback functions will be ignored and has no effect, so for performance reasons you're recommended to not return any excessive data structures. Every implementation of this interface MUST follow these event semantics in order to be considered a well-behaving stream. > Note that higher-level implementations of this interface may choose to define additional events with dedicated semantics not defined as part of this low-level stream specification. Conformance with these event semantics is out of scope for this interface, so you may also have to refer to the documentation of such a higher-level implementation. #### data event The `data` event will be emitted whenever some data was read/received from this source stream. The event receives a single mixed argument for incoming data. ```php $stream->on('data', function ($data) { echo $data; }); ``` This event MAY be emitted any number of times, which may be zero times if this stream does not send any data at all. It SHOULD not be emitted after an `end` or `close` event. The given `$data` argument may be of mixed type, but it's usually recommended it SHOULD be a `string` value or MAY use a type that allows representation as a `string` for maximum compatibility. Many common streams (such as a TCP/IP connection or a file-based stream) will emit the raw (binary) payload data that is received over the wire as chunks of `string` values. Due to the stream-based nature of this, the sender may send any number of chunks with varying sizes. There are no guarantees that these chunks will be received with the exact same framing the sender intended to send. In other words, many lower-level protocols (such as TCP/IP) transfer the data in chunks that may be anywhere between single-byte values to several dozens of kilobytes. You may want to apply a higher-level protocol to these low-level data chunks in order to achieve proper message framing. #### end event The `end` event will be emitted once the source stream has successfully reached the end of the stream (EOF). ```php $stream->on('end', function () { echo 'END'; }); ``` This event SHOULD be emitted once or never at all, depending on whether a successful end was detected. It SHOULD NOT be emitted after a previous `end` or `close` event. It MUST NOT be emitted if the stream closes due to a non-successful end, such as after a previous `error` event. After the stream is ended, it MUST switch to non-readable mode, see also `isReadable()`. This event will only be emitted if the *end* was reached successfully, not if the stream was interrupted by an unrecoverable error or explicitly closed. Not all streams know this concept of a "successful end". Many use-cases involve detecting when the stream closes (terminates) instead, in this case you should use the `close` event. After the stream emits an `end` event, it SHOULD usually be followed by a `close` event. Many common streams (such as a TCP/IP connection or a file-based stream) will emit this event if either the remote side closes the connection or a file handle was successfully read until reaching its end (EOF). Note that this event should not be confused with the `end()` method. This event defines a successful end *reading* from a source stream, while the `end()` method defines *writing* a successful end to a destination stream. #### error event The `error` event will be emitted once a fatal error occurs, usually while trying to read from this stream. The event receives a single `Exception` argument for the error instance. ```php $server->on('error', function (Exception $e) { echo 'Error: ' . $e->getMessage() . PHP_EOL; }); ``` This event SHOULD be emitted once the stream detects a fatal error, such as a fatal transmission error or after an unexpected `data` or premature `end` event. It SHOULD NOT be emitted after a previous `error`, `end` or `close` event. It MUST NOT be emitted if this is not a fatal error condition, such as a temporary network issue that did not cause any data to be lost. After the stream errors, it MUST close the stream and SHOULD thus be followed by a `close` event and then switch to non-readable mode, see also `close()` and `isReadable()`. Many common streams (such as a TCP/IP connection or a file-based stream) only deal with data transmission and do not make assumption about data boundaries (such as unexpected `data` or premature `end` events). In other words, many lower-level protocols (such as TCP/IP) may choose to only emit this for a fatal transmission error once and will then close (terminate) the stream in response. If this stream is a `DuplexStreamInterface`, you should also notice how the writable side of the stream also implements an `error` event. In other words, an error may occur while either reading or writing the stream which should result in the same error processing. #### close event The `close` event will be emitted once the stream closes (terminates). ```php $stream->on('close', function () { echo 'CLOSED'; }); ``` This event SHOULD be emitted once or never at all, depending on whether the stream ever terminates. It SHOULD NOT be emitted after a previous `close` event. After the stream is closed, it MUST switch to non-readable mode, see also `isReadable()`. Unlike the `end` event, this event SHOULD be emitted whenever the stream closes, irrespective of whether this happens implicitly due to an unrecoverable error or explicitly when either side closes the stream. If you only want to detect a *successful* end, you should use the `end` event instead. Many common streams (such as a TCP/IP connection or a file-based stream) will likely choose to emit this event after reading a *successful* `end` event or after a fatal transmission `error` event. If this stream is a `DuplexStreamInterface`, you should also notice how the writable side of the stream also implements a `close` event. In other words, after receiving this event, the stream MUST switch into non-writable AND non-readable mode, see also `isWritable()`. Note that this event should not be confused with the `end` event. #### isReadable() The `isReadable(): bool` method can be used to check whether this stream is in a readable state (not closed already). This method can be used to check if the stream still accepts incoming data events or if it is ended or closed already. Once the stream is non-readable, no further `data` or `end` events SHOULD be emitted. ```php assert($stream->isReadable() === false); $stream->on('data', assertNeverCalled()); $stream->on('end', assertNeverCalled()); ``` A successfully opened stream always MUST start in readable mode. Once the stream ends or closes, it MUST switch to non-readable mode. This can happen any time, explicitly through `close()` or implicitly due to a remote close or an unrecoverable transmission error. Once a stream has switched to non-readable mode, it MUST NOT transition back to readable mode. If this stream is a `DuplexStreamInterface`, you should also notice how the writable side of the stream also implements an `isWritable()` method. Unless this is a half-open duplex stream, they SHOULD usually have the same return value. #### pause() The `pause(): void` method can be used to pause reading incoming data events. Removes the data source file descriptor from the event loop. This allows you to throttle incoming data. Unless otherwise noted, a successfully opened stream SHOULD NOT start in paused state. Once the stream is paused, no futher `data` or `end` events SHOULD be emitted. ```php $stream->pause(); $stream->on('data', assertShouldNeverCalled()); $stream->on('end', assertShouldNeverCalled()); ``` This method is advisory-only, though generally not recommended, the stream MAY continue emitting `data` events. You can continue processing events by calling `resume()` again. Note that both methods can be called any number of times, in particular calling `pause()` more than once SHOULD NOT have any effect. See also `resume()`. #### resume() The `resume(): void` method can be used to resume reading incoming data events. Re-attach the data source after a previous `pause()`. ```php $stream->pause(); Loop::addTimer(1.0, function () use ($stream) { $stream->resume(); }); ``` Note that both methods can be called any number of times, in particular calling `resume()` without a prior `pause()` SHOULD NOT have any effect. See also `pause()`. #### pipe() The `pipe(WritableStreamInterface $dest, array $options = [])` method can be used to pipe all the data from this readable source into the given writable destination. Automatically sends all incoming data to the destination. Automatically throttles the source based on what the destination can handle. ```php $source->pipe($dest); ``` Similarly, you can also pipe an instance implementing `DuplexStreamInterface` into itself in order to write back all the data that is received. This may be a useful feature for a TCP/IP echo service: ```php $connection->pipe($connection); ``` This method returns the destination stream as-is, which can be used to set up chains of piped streams: ```php $source->pipe($decodeGzip)->pipe($filterBadWords)->pipe($dest); ``` By default, this will call `end()` on the destination stream once the source stream emits an `end` event. This can be disabled like this: ```php $source->pipe($dest, array('end' => false)); ``` Note that this only applies to the `end` event. If an `error` or explicit `close` event happens on the source stream, you'll have to manually close the destination stream: ```php $source->pipe($dest); $source->on('close', function () use ($dest) { $dest->end('BYE!'); }); ``` If the source stream is not readable (closed state), then this is a NO-OP. ```php $source->close(); $source->pipe($dest); // NO-OP ``` If the destinantion stream is not writable (closed state), then this will simply throttle (pause) the source stream: ```php $dest->close(); $source->pipe($dest); // calls $source->pause() ``` Similarly, if the destination stream is closed while the pipe is still active, it will also throttle (pause) the source stream: ```php $source->pipe($dest); $dest->close(); // calls $source->pause() ``` Once the pipe is set up successfully, the destination stream MUST emit a `pipe` event with this source stream an event argument. #### close() The `close(): void` method can be used to close the stream (forcefully). This method can be used to (forcefully) close the stream. ```php $stream->close(); ``` Once the stream is closed, it SHOULD emit a `close` event. Note that this event SHOULD NOT be emitted more than once, in particular if this method is called multiple times. After calling this method, the stream MUST switch into a non-readable mode, see also `isReadable()`. This means that no further `data` or `end` events SHOULD be emitted. ```php $stream->close(); assert($stream->isReadable() === false); $stream->on('data', assertNeverCalled()); $stream->on('end', assertNeverCalled()); ``` If this stream is a `DuplexStreamInterface`, you should also notice how the writable side of the stream also implements a `close()` method. In other words, after calling this method, the stream MUST switch into non-writable AND non-readable mode, see also `isWritable()`. Note that this method should not be confused with the `end()` method. ### WritableStreamInterface The `WritableStreamInterface` is responsible for providing an interface for write-only streams and the writable side of duplex streams. Besides defining a few methods, this interface also implements the `EventEmitterInterface` which allows you to react to certain events. The event callback functions MUST be a valid `callable` that obeys strict parameter definitions and MUST accept event parameters exactly as documented. The event callback functions MUST NOT throw an `Exception`. The return value of the event callback functions will be ignored and has no effect, so for performance reasons you're recommended to not return any excessive data structures. Every implementation of this interface MUST follow these event semantics in order to be considered a well-behaving stream. > Note that higher-level implementations of this interface may choose to define additional events with dedicated semantics not defined as part of this low-level stream specification. Conformance with these event semantics is out of scope for this interface, so you may also have to refer to the documentation of such a higher-level implementation. #### drain event The `drain` event will be emitted whenever the write buffer became full previously and is now ready to accept more data. ```php $stream->on('drain', function () use ($stream) { echo 'Stream is now ready to accept more data'; }); ``` This event SHOULD be emitted once every time the buffer became full previously and is now ready to accept more data. In other words, this event MAY be emitted any number of times, which may be zero times if the buffer never became full in the first place. This event SHOULD NOT be emitted if the buffer has not become full previously. This event is mostly used internally, see also `write()` for more details. #### pipe event The `pipe` event will be emitted whenever a readable stream is `pipe()`d into this stream. The event receives a single `ReadableStreamInterface` argument for the source stream. ```php $stream->on('pipe', function (ReadableStreamInterface $source) use ($stream) { echo 'Now receiving piped data'; // explicitly close target if source emits an error $source->on('error', function () use ($stream) { $stream->close(); }); }); $source->pipe($stream); ``` This event MUST be emitted once for each readable stream that is successfully piped into this destination stream. In other words, this event MAY be emitted any number of times, which may be zero times if no stream is ever piped into this stream. This event MUST NOT be emitted if either the source is not readable (closed already) or this destination is not writable (closed already). This event is mostly used internally, see also `pipe()` for more details. #### error event The `error` event will be emitted once a fatal error occurs, usually while trying to write to this stream. The event receives a single `Exception` argument for the error instance. ```php $stream->on('error', function (Exception $e) { echo 'Error: ' . $e->getMessage() . PHP_EOL; }); ``` This event SHOULD be emitted once the stream detects a fatal error, such as a fatal transmission error. It SHOULD NOT be emitted after a previous `error` or `close` event. It MUST NOT be emitted if this is not a fatal error condition, such as a temporary network issue that did not cause any data to be lost. After the stream errors, it MUST close the stream and SHOULD thus be followed by a `close` event and then switch to non-writable mode, see also `close()` and `isWritable()`. Many common streams (such as a TCP/IP connection or a file-based stream) only deal with data transmission and may choose to only emit this for a fatal transmission error once and will then close (terminate) the stream in response. If this stream is a `DuplexStreamInterface`, you should also notice how the readable side of the stream also implements an `error` event. In other words, an error may occur while either reading or writing the stream which should result in the same error processing. #### close event The `close` event will be emitted once the stream closes (terminates). ```php $stream->on('close', function () { echo 'CLOSED'; }); ``` This event SHOULD be emitted once or never at all, depending on whether the stream ever terminates. It SHOULD NOT be emitted after a previous `close` event. After the stream is closed, it MUST switch to non-writable mode, see also `isWritable()`. This event SHOULD be emitted whenever the stream closes, irrespective of whether this happens implicitly due to an unrecoverable error or explicitly when either side closes the stream. Many common streams (such as a TCP/IP connection or a file-based stream) will likely choose to emit this event after flushing the buffer from the `end()` method, after receiving a *successful* `end` event or after a fatal transmission `error` event. If this stream is a `DuplexStreamInterface`, you should also notice how the readable side of the stream also implements a `close` event. In other words, after receiving this event, the stream MUST switch into non-writable AND non-readable mode, see also `isReadable()`. Note that this event should not be confused with the `end` event. #### isWritable() The `isWritable(): bool` method can be used to check whether this stream is in a writable state (not closed already). This method can be used to check if the stream still accepts writing any data or if it is ended or closed already. Writing any data to a non-writable stream is a NO-OP: ```php assert($stream->isWritable() === false); $stream->write('end'); // NO-OP $stream->end('end'); // NO-OP ``` A successfully opened stream always MUST start in writable mode. Once the stream ends or closes, it MUST switch to non-writable mode. This can happen any time, explicitly through `end()` or `close()` or implicitly due to a remote close or an unrecoverable transmission error. Once a stream has switched to non-writable mode, it MUST NOT transition back to writable mode. If this stream is a `DuplexStreamInterface`, you should also notice how the readable side of the stream also implements an `isReadable()` method. Unless this is a half-open duplex stream, they SHOULD usually have the same return value. #### write() The `write(mixed $data): bool` method can be used to write some data into the stream. A successful write MUST be confirmed with a boolean `true`, which means that either the data was written (flushed) immediately or is buffered and scheduled for a future write. Note that this interface gives you no control over explicitly flushing the buffered data, as finding the appropriate time for this is beyond the scope of this interface and left up to the implementation of this interface. Many common streams (such as a TCP/IP connection or file-based stream) may choose to buffer all given data and schedule a future flush by using an underlying EventLoop to check when the resource is actually writable. If a stream cannot handle writing (or flushing) the data, it SHOULD emit an `error` event and MAY `close()` the stream if it can not recover from this error. If the internal buffer is full after adding `$data`, then `write()` SHOULD return `false`, indicating that the caller should stop sending data until the buffer drains. The stream SHOULD send a `drain` event once the buffer is ready to accept more data. Similarly, if the the stream is not writable (already in a closed state) it MUST NOT process the given `$data` and SHOULD return `false`, indicating that the caller should stop sending data. The given `$data` argument MAY be of mixed type, but it's usually recommended it SHOULD be a `string` value or MAY use a type that allows representation as a `string` for maximum compatibility. Many common streams (such as a TCP/IP connection or a file-based stream) will only accept the raw (binary) payload data that is transferred over the wire as chunks of `string` values. Due to the stream-based nature of this, the sender may send any number of chunks with varying sizes. There are no guarantees that these chunks will be received with the exact same framing the sender intended to send. In other words, many lower-level protocols (such as TCP/IP) transfer the data in chunks that may be anywhere between single-byte values to several dozens of kilobytes. You may want to apply a higher-level protocol to these low-level data chunks in order to achieve proper message framing. #### end() The `end(mixed $data = null): void` method can be used to successfully end the stream (after optionally sending some final data). This method can be used to successfully end the stream, i.e. close the stream after sending out all data that is currently buffered. ```php $stream->write('hello'); $stream->write('world'); $stream->end(); ``` If there's no data currently buffered and nothing to be flushed, then this method MAY `close()` the stream immediately. If there's still data in the buffer that needs to be flushed first, then this method SHOULD try to write out this data and only then `close()` the stream. Once the stream is closed, it SHOULD emit a `close` event. Note that this interface gives you no control over explicitly flushing the buffered data, as finding the appropriate time for this is beyond the scope of this interface and left up to the implementation of this interface. Many common streams (such as a TCP/IP connection or file-based stream) may choose to buffer all given data and schedule a future flush by using an underlying EventLoop to check when the resource is actually writable. You can optionally pass some final data that is written to the stream before ending the stream. If a non-`null` value is given as `$data`, then this method will behave just like calling `write($data)` before ending with no data. ```php // shorter version $stream->end('bye'); // same as longer version $stream->write('bye'); $stream->end(); ``` After calling this method, the stream MUST switch into a non-writable mode, see also `isWritable()`. This means that no further writes are possible, so any additional `write()` or `end()` calls have no effect. ```php $stream->end(); assert($stream->isWritable() === false); $stream->write('nope'); // NO-OP $stream->end(); // NO-OP ``` If this stream is a `DuplexStreamInterface`, calling this method SHOULD also end its readable side, unless the stream supports half-open mode. In other words, after calling this method, these streams SHOULD switch into non-writable AND non-readable mode, see also `isReadable()`. This implies that in this case, the stream SHOULD NOT emit any `data` or `end` events anymore. Streams MAY choose to use the `pause()` method logic for this, but special care may have to be taken to ensure a following call to the `resume()` method SHOULD NOT continue emitting readable events. Note that this method should not be confused with the `close()` method. #### close() The `close(): void` method can be used to close the stream (forcefully). This method can be used to forcefully close the stream, i.e. close the stream without waiting for any buffered data to be flushed. If there's still data in the buffer, this data SHOULD be discarded. ```php $stream->close(); ``` Once the stream is closed, it SHOULD emit a `close` event. Note that this event SHOULD NOT be emitted more than once, in particular if this method is called multiple times. After calling this method, the stream MUST switch into a non-writable mode, see also `isWritable()`. This means that no further writes are possible, so any additional `write()` or `end()` calls have no effect. ```php $stream->close(); assert($stream->isWritable() === false); $stream->write('nope'); // NO-OP $stream->end(); // NO-OP ``` Note that this method should not be confused with the `end()` method. Unlike the `end()` method, this method does not take care of any existing buffers and simply discards any buffer contents. Likewise, this method may also be called after calling `end()` on a stream in order to stop waiting for the stream to flush its final data. ```php $stream->end(); Loop::addTimer(1.0, function () use ($stream) { $stream->close(); }); ``` If this stream is a `DuplexStreamInterface`, you should also notice how the readable side of the stream also implements a `close()` method. In other words, after calling this method, the stream MUST switch into non-writable AND non-readable mode, see also `isReadable()`. ### DuplexStreamInterface The `DuplexStreamInterface` is responsible for providing an interface for duplex streams (both readable and writable). It builds on top of the existing interfaces for readable and writable streams and follows the exact same method and event semantics. If you're new to this concept, you should look into the `ReadableStreamInterface` and `WritableStreamInterface` first. Besides defining a few methods, this interface also implements the `EventEmitterInterface` which allows you to react to the same events defined on the `ReadbleStreamInterface` and `WritableStreamInterface`. The event callback functions MUST be a valid `callable` that obeys strict parameter definitions and MUST accept event parameters exactly as documented. The event callback functions MUST NOT throw an `Exception`. The return value of the event callback functions will be ignored and has no effect, so for performance reasons you're recommended to not return any excessive data structures. Every implementation of this interface MUST follow these event semantics in order to be considered a well-behaving stream. > Note that higher-level implementations of this interface may choose to define additional events with dedicated semantics not defined as part of this low-level stream specification. Conformance with these event semantics is out of scope for this interface, so you may also have to refer to the documentation of such a higher-level implementation. See also [`ReadableStreamInterface`](#readablestreaminterface) and [`WritableStreamInterface`](#writablestreaminterface) for more details. ## Creating streams ReactPHP uses the concept of "streams" throughout its ecosystem, so that many higher-level consumers of this package only deal with [stream usage](#stream-usage). This implies that stream instances are most often created within some higher-level components and many consumers never actually have to deal with creating a stream instance. * Use [react/socket](https://github.com/reactphp/socket) if you want to accept incoming or establish outgoing plaintext TCP/IP or secure TLS socket connection streams. * Use [react/http](https://github.com/reactphp/http) if you want to receive an incoming HTTP request body streams. * Use [react/child-process](https://github.com/reactphp/child-process) if you want to communicate with child processes via process pipes such as STDIN, STDOUT, STDERR etc. * Use experimental [react/filesystem](https://github.com/reactphp/filesystem) if you want to read from / write to the filesystem. * See also the last chapter for [more real-world applications](#more). However, if you are writing a lower-level component or want to create a stream instance from a stream resource, then the following chapter is for you. > Note that the following examples use `fopen()` and `stream_socket_client()` for illustration purposes only. These functions SHOULD NOT be used in a truly async program because each call may take several seconds to complete and would block the EventLoop otherwise. Additionally, the `fopen()` call will return a file handle on some platforms which may or may not be supported by all EventLoop implementations. As an alternative, you may want to use higher-level libraries listed above. ### ReadableResourceStream The `ReadableResourceStream` is a concrete implementation of the [`ReadableStreamInterface`](#readablestreaminterface) for PHP's stream resources. This can be used to represent a read-only resource like a file stream opened in readable mode or a stream such as `STDIN`: ```php $stream = new ReadableResourceStream(STDIN); $stream->on('data', function ($chunk) { echo $chunk; }); $stream->on('end', function () { echo 'END'; }); ``` See also [`ReadableStreamInterface`](#readablestreaminterface) for more details. The first parameter given to the constructor MUST be a valid stream resource that is opened in reading mode (e.g. `fopen()` mode `r`). Otherwise, it will throw an `InvalidArgumentException`: ```php // throws InvalidArgumentException $stream = new ReadableResourceStream(false); ``` See also the [`DuplexResourceStream`](#readableresourcestream) for read-and-write stream resources otherwise. Internally, this class tries to enable non-blocking mode on the stream resource which may not be supported for all stream resources. Most notably, this is not supported by pipes on Windows (STDIN etc.). If this fails, it will throw a `RuntimeException`: ```php // throws RuntimeException on Windows $stream = new ReadableResourceStream(STDIN); ``` Once the constructor is called with a valid stream resource, this class will take care of the underlying stream resource. You SHOULD only use its public API and SHOULD NOT interfere with the underlying stream resource manually. This class takes an optional `LoopInterface|null $loop` parameter that can be used to pass the event loop instance to use for this object. You can use a `null` value here in order to use the [default loop](https://github.com/reactphp/event-loop#loop). This value SHOULD NOT be given unless you're sure you want to explicitly use a given event loop instance. This class takes an optional `int|null $readChunkSize` parameter that controls the maximum buffer size in bytes to read at once from the stream. You can use a `null` value here in order to apply its default value. This value SHOULD NOT be changed unless you know what you're doing. This can be a positive number which means that up to X bytes will be read at once from the underlying stream resource. Note that the actual number of bytes read may be lower if the stream resource has less than X bytes currently available. This can be `-1` which means "read everything available" from the underlying stream resource. This should read until the stream resource is not readable anymore (i.e. underlying buffer drained), note that this does not neccessarily mean it reached EOF. ```php $stream = new ReadableResourceStream(STDIN, null, 8192); ``` > PHP bug warning: If the PHP process has explicitly been started without a `STDIN` stream, then trying to read from `STDIN` may return data from another stream resource. This does not happen if you start this with an empty stream like `php test.php < /dev/null` instead of `php test.php <&-`. See [#81](https://github.com/reactphp/stream/issues/81) for more details. > Changelog: As of v1.2.0 the `$loop` parameter can be omitted (or skipped with a `null` value) to use the [default loop](https://github.com/reactphp/event-loop#loop). ### WritableResourceStream The `WritableResourceStream` is a concrete implementation of the [`WritableStreamInterface`](#writablestreaminterface) for PHP's stream resources. This can be used to represent a write-only resource like a file stream opened in writable mode or a stream such as `STDOUT` or `STDERR`: ```php $stream = new WritableResourceStream(STDOUT); $stream->write('hello!'); $stream->end(); ``` See also [`WritableStreamInterface`](#writablestreaminterface) for more details. The first parameter given to the constructor MUST be a valid stream resource that is opened for writing. Otherwise, it will throw an `InvalidArgumentException`: ```php // throws InvalidArgumentException $stream = new WritableResourceStream(false); ``` See also the [`DuplexResourceStream`](#readableresourcestream) for read-and-write stream resources otherwise. Internally, this class tries to enable non-blocking mode on the stream resource which may not be supported for all stream resources. Most notably, this is not supported by pipes on Windows (STDOUT, STDERR etc.). If this fails, it will throw a `RuntimeException`: ```php // throws RuntimeException on Windows $stream = new WritableResourceStream(STDOUT); ``` Once the constructor is called with a valid stream resource, this class will take care of the underlying stream resource. You SHOULD only use its public API and SHOULD NOT interfere with the underlying stream resource manually. Any `write()` calls to this class will not be performed instantly, but will be performed asynchronously, once the EventLoop reports the stream resource is ready to accept data. For this, it uses an in-memory buffer string to collect all outstanding writes. This buffer has a soft-limit applied which defines how much data it is willing to accept before the caller SHOULD stop sending further data. This class takes an optional `LoopInterface|null $loop` parameter that can be used to pass the event loop instance to use for this object. You can use a `null` value here in order to use the [default loop](https://github.com/reactphp/event-loop#loop). This value SHOULD NOT be given unless you're sure you want to explicitly use a given event loop instance. This class takes an optional `int|null $writeBufferSoftLimit` parameter that controls this maximum buffer size in bytes. You can use a `null` value here in order to apply its default value. This value SHOULD NOT be changed unless you know what you're doing. ```php $stream = new WritableResourceStream(STDOUT, null, 8192); ``` This class takes an optional `int|null $writeChunkSize` parameter that controls this maximum buffer size in bytes to write at once to the stream. You can use a `null` value here in order to apply its default value. This value SHOULD NOT be changed unless you know what you're doing. This can be a positive number which means that up to X bytes will be written at once to the underlying stream resource. Note that the actual number of bytes written may be lower if the stream resource has less than X bytes currently available. This can be `-1` which means "write everything available" to the underlying stream resource. ```php $stream = new WritableResourceStream(STDOUT, null, null, 8192); ``` See also [`write()`](#write) for more details. > Changelog: As of v1.2.0 the `$loop` parameter can be omitted (or skipped with a `null` value) to use the [default loop](https://github.com/reactphp/event-loop#loop). ### DuplexResourceStream The `DuplexResourceStream` is a concrete implementation of the [`DuplexStreamInterface`](#duplexstreaminterface) for PHP's stream resources. This can be used to represent a read-and-write resource like a file stream opened in read and write mode mode or a stream such as a TCP/IP connection: ```php $conn = stream_socket_client('tcp://google.com:80'); $stream = new DuplexResourceStream($conn); $stream->write('hello!'); $stream->end(); ``` See also [`DuplexStreamInterface`](#duplexstreaminterface) for more details. The first parameter given to the constructor MUST be a valid stream resource that is opened for reading *and* writing. Otherwise, it will throw an `InvalidArgumentException`: ```php // throws InvalidArgumentException $stream = new DuplexResourceStream(false); ``` See also the [`ReadableResourceStream`](#readableresourcestream) for read-only and the [`WritableResourceStream`](#writableresourcestream) for write-only stream resources otherwise. Internally, this class tries to enable non-blocking mode on the stream resource which may not be supported for all stream resources. Most notably, this is not supported by pipes on Windows (STDOUT, STDERR etc.). If this fails, it will throw a `RuntimeException`: ```php // throws RuntimeException on Windows $stream = new DuplexResourceStream(STDOUT); ``` Once the constructor is called with a valid stream resource, this class will take care of the underlying stream resource.

This can be a positive number which means that up to X bytes will be read at once from the underlying stream resource. Note that the actual number of bytes read may be lower if the stream resource has less than X bytes currently available. This can be `-1` which means "read everything available" from the underlying stream resource. This should read until the stream resource is not readable anymore (i.e. underlying buffer drained), note that this does not neccessarily mean it reached EOF. ```php $conn = stream_socket_client('tcp://google.com:80'); $stream = new DuplexResourceStream($conn, null, 8192); ``` Any `write()` calls to this class will not be performed instantly, but will be performed asynchronously, once the EventLoop reports the stream resource is ready to accept data. For this, it uses an in-memory buffer string to collect all outstanding writes. This buffer has a soft-limit applied which defines how much data it is willing to accept before the caller SHOULD stop sending further data. This class takes another optional `WritableStreamInterface|null $buffer` parameter that controls this write behavior of this stream. You can use a `null` value here in order to apply its default value. This value SHOULD NOT be changed unless you know what you're doing. If you want to change the write buffer soft limit, you can pass an instance of [`WritableResourceStream`](#writableresourcestream) like this: ```php $conn = stream_socket_client('tcp://google.com:80'); $buffer = new WritableResourceStream($conn, null, 8192); $stream = new DuplexResourceStream($conn, null, null, $buffer); ``` See also [`WritableResourceStream`](#writableresourcestream) for more details. > Changelog: As of v1.2.0 the `$loop` parameter can be omitted (or skipped with a `null` value) to use the [default loop](https://github.com/reactphp/event-loop#loop). ### ThroughStream The `ThroughStream` implements the [`DuplexStreamInterface`](#duplexstreaminterface) and will simply pass any data you write to it through to its readable end. ```php $through = new ThroughStream(); $through->on('data', $this->expectCallableOnceWith('hello')); $through->write('hello'); ``` Similarly, the [`end()` method](#end) will end the stream and emit an [`end` event](#end-event) and then [`close()`](#close-1) the stream. The [`close()` method](#close-1) will close the stream and emit a [`close` event](#close-event). Accordingly, this is can also be used in a [`pipe()`](#pipe) context like this: ```php $through = new ThroughStream(); $source->pipe($through)->pipe($dest); ``` Optionally, its constructor accepts any callable function which will then be used to *filter* any data written to it. This function receives a single data argument as passed to the writable side and must return the data as it will be passed to its readable end: ```php $through = new ThroughStream('strtoupper'); $source->pipe($through)->pipe($dest); ``` Note that this class makes no assumptions about any data types. This can be used to convert data, for example for transforming any structured data into a newline-delimited JSON (NDJSON) stream like this: ```php $through = new ThroughStream(function ($data) { return json_encode($data) . PHP_EOL; }); $through->on('data', $this->expectCallableOnceWith("[2, true]\n")); $through->write(array(2, true)); ``` The callback function is allowed to throw an `Exception`. In this case, the stream will emit an `error` event and then [`close()`](#close-1) the stream. ```php $through = new ThroughStream(function ($data) { if (!is_string($data)) { throw new \UnexpectedValueException('Only strings allowed'); } return $data; }); $through->on('error', $this->expectCallableOnce())); $through->on('close', $this->expectCallableOnce())); $through->on('data', $this->expectCallableNever())); $through->write(2); ``` ### CompositeStream The `CompositeStream` implements the [`DuplexStreamInterface`](#duplexstreaminterface) and can be used to create a single duplex stream from two individual streams implementing [`ReadableStreamInterface`](#readablestreaminterface) and [`WritableStreamInterface`](#writablestreaminterface) respectively. This is useful for some APIs which may require a single [`DuplexStreamInterface`](#duplexstreaminterface) or simply because it's often more convenient to work with a single stream instance like this: ```php $stdin = new ReadableResourceStream(STDIN); $stdout = new WritableResourceStream(STDOUT); $stdio = new CompositeStream($stdin, $stdout); $stdio->on('data', function ($chunk) use ($stdio) { $stdio->write('You said: ' . $chunk); }); ``` This is a well-behaving stream which forwards all stream events from the underlying streams and forwards all streams calls to the underlying streams. If you `write()` to the duplex stream, it will simply `write()` to the writable side and return its status. If you `end()` the duplex stream, it will `end()` the writable side and will `pause()` the readable side. If you `close()` the duplex stream, both input streams will be closed. If either of the two input streams emits a `close` event, the duplex stream will also close. If either of the two input streams is already closed while constructing the duplex stream, it will `close()` the other side and return a closed stream. ## Usage The following example can be used to pipe the contents of a source file into a destination file without having to ever read the whole file into memory: ```php $source = new React\Stream\ReadableResourceStream(fopen('source.txt', 'r')); $dest = new React\Stream\WritableResourceStream(fopen('destination.txt', 'w')); $source->pipe($dest); ``` > Note that this example uses `fopen()` for illustration purposes only. This should not be used in a truly async program because the filesystem is inherently blocking and each call could potentially take several seconds.

We'd like to emphasize that this component is production ready and battle-tested. We plan to support all long-term support (LTS) releases for at least 24 months, so you have a rock-solid foundation to build on top of. This update involves a number of BC breaks due to dropped support for deprecated functionality and some internal API cleanup. We've tried hard to avoid BC breaks where possible and minimize impact otherwise. We expect that most consumers of this package will actually not be affected by any BC breaks, see below for more details: * BC break: Delete all deprecated APIs, use `Query` objects for `Message` questions instead of nested arrays and increase code coverage to 100%. (#130 by @clue) * BC break: Move `$nameserver` from `ExecutorInterface` to `UdpTransportExecutor`, remove advanced/internal `UdpTransportExecutor` args for `Parser`/`BinaryDumper` and add API documentation for `ExecutorInterface`. (#135, #137 and #138 by @clue) * BC break: Replace `HeaderBag` attributes with simple `Message` properties. (#132 by @clue) * BC break: Mark all `Record` attributes as required, add documentation vs `Query`.

(#133 by @clue) ## 0.4.18 (2019-09-07) * Feature / Fix: Implement `CachingExecutor` using cache TTL, deprecate old `CachedExecutor`, respect TTL from response records when caching and do not cache truncated responses. (#129 by @clue) * Feature: Limit cache size to 256 last responses by default. (#127 by @clue) * Feature: Cooperatively resolve hosts to avoid running same query concurrently. (#125 by @clue) ## 0.4.17 (2019-04-01) * Feature: Support parsing `authority` and `additional` records from DNS response. (#123 by @clue) * Feature: Support dumping records as part of outgoing binary DNS message. (#124 by @clue) * Feature: Forward compatibility with upcoming Cache v0.6 and Cache v1.0 (#121 by @clue) * Improve test suite to add forward compatibility with PHPUnit 7, test against PHP 7.3 and use legacy PHPUnit 5 on legacy HHVM. (#122 by @clue) ## 0.4.16 (2018-11-11) * Feature: Improve promise cancellation for DNS lookup retries and clean up any garbage references. (#118 by @clue) * Fix: Reject parsing malformed DNS response messages such as incomplete DNS response messages, malformed record data or malformed compressed domain name labels. (#115 and #117 by @clue) * Fix: Fix interpretation of TTL as UINT32 with most significant bit unset. (#116 by @clue) * Fix: Fix caching advanced MX/SRV/TXT/SOA structures. (#112 by @clue) ## 0.4.15 (2018-07-02) * Feature: Add `resolveAll()` method to support custom query types in `Resolver`. (#110 by @clue and @WyriHaximus) ```php $resolver->resolveAll('reactphp.org', Message::TYPE_AAAA)->then(function ($ips) { echo 'IPv6 addresses for reactphp.org ' . implode(', ', $ips) . PHP_EOL; }); ``` * Feature: Support parsing `NS`, `TXT`, `MX`, `SOA` and `SRV` records. (#104, #105, #106, #107 and #108 by @clue) * Feature: Add support for `Message::TYPE_ANY` and parse unknown types as binary data. (#104 by @clue) * Feature: Improve error messages for failed queries and improve documentation. (#109 by @clue) * Feature: Add reverse DNS lookup example. (#111 by @clue) ## 0.4.14 (2018-06-26) * Feature: Add `UdpTransportExecutor`, validate incoming DNS response messages to avoid cache poisoning attacks and deprecate legacy `Executor`. (#101 and #103 by @clue) * Feature: Forward compatibility with Cache 0.5 (#102 by @clue) * Deprecate legacy `Query::$currentTime` and binary parser data attributes to clean up and simplify API. (#99 by @clue) ## 0.4.13 (2018-02-27) * Add `Config::loadSystemConfigBlocking()` to load default system config and support parsing DNS config on all supported platforms (`/etc/resolv.conf` on Unix/Linux/Mac and WMIC on Windows) (#92, #93, #94 and #95 by @clue) ```php $config = Config::loadSystemConfigBlocking(); $server = $config->nameservers ? reset($config->nameservers) : '8.8.8.8'; ``` * Remove unneeded cyclic dependency on react/socket (#96 by @clue) ## 0.4.12 (2018-01-14) * Improve test suite by adding forward compatibility with PHPUnit 6, test against PHP 7.2, fix forward compatibility with upcoming EventLoop releases, add test group to skip integration tests relying on internet connection and add minor documentation improvements.

PK �q�\rr���; �; react/dns/README.mdnu �Iw�� # DNS [](https://github.com/reactphp/dns/actions) Async DNS resolver for [ReactPHP](https://reactphp.org/). The main point of the DNS component is to provide async DNS resolution. However, it is really a toolkit for working with DNS messages, and could easily be used to create a DNS server. **Table of contents** * [Basic usage](#basic-usage) * [Caching](#caching) * [Custom cache adapter](#custom-cache-adapter) * [ResolverInterface](#resolverinterface) * [resolve()](#resolve) * [resolveAll()](#resolveall) * [Advanced usage](#advanced-usage) * [UdpTransportExecutor](#udptransportexecutor) * [TcpTransportExecutor](#tcptransportexecutor) * [SelectiveTransportExecutor](#selectivetransportexecutor) * [HostsFileExecutor](#hostsfileexecutor) * [Install](#install) * [Tests](#tests) * [License](#license) * [References](#references) ## Basic usage The most basic usage is to just create a resolver through the resolver factory. All you need to give it is a nameserver, then you can start resolving names, baby! ```php $config = React\Dns\Config\Config::loadSystemConfigBlocking(); if (!$config->nameservers) { $config->nameservers[] = '8.8.8.8'; } $factory = new React\Dns\Resolver\Factory(); $dns = $factory->create($config); $dns->resolve('igor.io')->then(function ($ip) { echo "Host: $ip\n"; }); ``` See also the [first example](examples). The `Config` class can be used to load the system default config. This is an operation that may access the filesystem and block. Ideally, this method should thus be executed only once before the loop starts and not repeatedly while it is running. Note that this class may return an *empty* configuration if the system config can not be loaded. As such, you'll likely want to apply a default nameserver as above if none can be found. > Note that the factory loads the hosts file from the filesystem once when creating the resolver instance. Ideally, this method should thus be executed only once before the loop starts and not repeatedly while it is running. But there's more. ## Caching You can cache results by configuring the resolver to use a `CachedExecutor`: ```php $config = React\Dns\Config\Config::loadSystemConfigBlocking(); if (!$config->nameservers) { $config->nameservers[] = '8.8.8.8'; } $factory = new React\Dns\Resolver\Factory(); $dns = $factory->createCached($config); $dns->resolve('igor.io')->then(function ($ip) { echo "Host: $ip\n"; }); ... $dns->resolve('igor.io')->then(function ($ip) { echo "Host: $ip\n"; }); ``` If the first call returns before the second, only one query will be executed. The second result will be served from an in memory cache. This is particularly useful for long running scripts where the same hostnames have to be looked up multiple times. See also the [third example](examples). ### Custom cache adapter By default, the above will use an in memory cache. You can also specify a custom cache implementing [`CacheInterface`](https://github.com/reactphp/cache) to handle the record cache instead: ```php $cache = new React\Cache\ArrayCache(); $factory = new React\Dns\Resolver\Factory(); $dns = $factory->createCached('8.8.8.8', null, $cache); ``` See also the wiki for possible [cache implementations](https://github.com/reactphp/react/wiki/Users#cache-implementations). ## ResolverInterface <a id="resolver"><!-- legacy reference --></a> ### resolve() The `resolve(string $domain): PromiseInterface<string,Exception>` method can be used to resolve the given $domain name to a single IPv4 address (type `A` query). ```php $resolver->resolve('reactphp.org')->then(function ($ip) { echo 'IP for reactphp.org is ' . $ip . PHP_EOL; }); ``` This is one of the main methods in this package. It sends a DNS query for the given $domain name to your DNS server and returns a single IP address on success. If the DNS server sends a DNS response message that contains more than one IP address for this query, it will randomly pick one of the IP addresses from the response. If you want the full list of IP addresses or want to send a different type of query, you should use the [`resolveAll()`](#resolveall) method instead. If the DNS server sends a DNS response message that indicates an error code, this method will reject with a `RecordNotFoundException`. Its message and code can be used to check for the response code. If the DNS communication fails and the server does not respond with a valid response message, this message will reject with an `Exception`. Pending DNS queries can be cancelled by cancelling its pending promise like so: ```php $promise = $resolver->resolve('reactphp.org'); $promise->cancel(); ``` ### resolveAll() The `resolveAll(string $host, int $type): PromiseInterface<array,Exception>` method can be used to resolve all record values for the given $domain name and query $type. ```php $resolver->resolveAll('reactphp.org', Message::TYPE_A)->then(function ($ips) { echo 'IPv4 addresses for reactphp.org ' . implode(', ', $ips) . PHP_EOL; }); $resolver->resolveAll('reactphp.org', Message::TYPE_AAAA)->then(function ($ips) { echo 'IPv6 addresses for reactphp.org ' . implode(', ', $ips) . PHP_EOL; }); ``` This is one of the main methods in this package. It sends a DNS query for the given $domain name to your DNS server and returns a list with all record values on success. If the DNS server sends a DNS response message that contains one or more records for this query, it will return a list with all record values from the response. You can use the `Message::TYPE_*` constants to control which type of query will be sent. Note that this method always returns a list of record values, but each record value type depends on the query type. For example, it returns the IPv4 addresses for type `A` queries, the IPv6 addresses for type `AAAA` queries, the hostname for type `NS`, `CNAME` and `PTR` queries and structured data for other queries. See also the `Record` documentation for more details. If the DNS server sends a DNS response message that indicates an error code, this method will reject with a `RecordNotFoundException`. Its message and code can be used to check for the response code. If the DNS communication fails and the server does not respond with a valid response message, this message will reject with an `Exception`. Pending DNS queries can be cancelled by cancelling its pending promise like so: ```php $promise = $resolver->resolveAll('reactphp.org', Message::TYPE_AAAA); $promise->cancel(); ``` ## Advanced Usage ### UdpTransportExecutor The `UdpTransportExecutor` can be used to send DNS queries over a UDP transport. This is the main class that sends a DNS query to your DNS server and is used internally by the `Resolver` for the actual message transport. For more advanced usages one can utilize this class directly. The following example looks up the `IPv6` address for `igor.io`. ```php $executor = new UdpTransportExecutor('8.8.8.8:53'); $executor->query( new Query($name, Message::TYPE_AAAA, Message::CLASS_IN) )->then(function (Message $message) { foreach ($message->answers as $answer) { echo 'IPv6: ' . $answer->data . PHP_EOL; } }, 'printf'); ``` See also the [fourth example](examples). Note that this executor does not implement a timeout, so you will very likely want to use this in combination with a `TimeoutExecutor` like this: ```php $executor = new TimeoutExecutor( new UdpTransportExecutor($nameserver), 3.0 ); ``` Also note that this executor uses an unreliable UDP transport and that it does not implement any retry logic, so you will likely want to use this in combination with a `RetryExecutor` like this: ```php $executor = new RetryExecutor( new TimeoutExecutor( new UdpTransportExecutor($nameserver), 3.0 ) ); ``` Note that this executor is entirely async and as such allows you to execute any number of queries concurrently. You should probably limit the number of concurrent queries in your application or you're very likely going to face rate limitations and bans on the resolver end. For many common applications, you may want to avoid sending the same query multiple times when the first one is still pending, so you will likely want to use this in combination with a `CoopExecutor` like this: ```php $executor = new CoopExecutor( new RetryExecutor( new TimeoutExecutor( new UdpTransportExecutor($nameserver), 3.0 ) ) ); ``` > Internally, this class uses PHP's UDP sockets and does not take advantage of [react/datagram](https://github.com/reactphp/datagram) purely for organizational reasons to avoid a cyclic dependency between the two packages. Higher-level components should take advantage of the Datagram component instead of reimplementing this socket logic from scratch. ### TcpTransportExecutor The `TcpTransportExecutor` class can be used to send DNS queries over a TCP/IP stream transport. This is one of the main classes that send a DNS query to your DNS server. For more advanced usages one can utilize this class directly. The following example looks up the `IPv6` address for `reactphp.org`. ```php $executor = new TcpTransportExecutor('8.8.8.8:53'); $executor->query( new Query($name, Message::TYPE_AAAA, Message::CLASS_IN) )->then(function (Message $message) { foreach ($message->answers as $answer) { echo 'IPv6: ' . $answer->data . PHP_EOL; } }, 'printf'); ``` See also [example #92](examples). Note that this executor does not implement a timeout, so you will very likely want to use this in combination with a `TimeoutExecutor` like this: ```php $executor = new TimeoutExecutor( new TcpTransportExecutor($nameserver), 3.0 ); ``` Unlike the `UdpTransportExecutor`, this class uses a reliable TCP/IP transport, so you do not necessarily have to implement any retry logic. Note that this executor is entirely async and as such allows you to execute queries concurrently. The first query will establish a TCP/IP socket connection to the DNS server which will be kept open for a short period. Additional queries will automatically reuse this existing socket connection to the DNS server, will pipeline multiple requests over this single connection and will keep an idle connection open for a short period. The initial TCP/IP connection overhead may incur a slight delay if you only send occasional queries – when sending a larger number of concurrent queries over an existing connection, it becomes increasingly more efficient and avoids creating many concurrent sockets like the UDP-based executor. You may still want to limit the number of (concurrent) queries in your application or you may be facing rate limitations and bans on the resolver end. For many common applications, you may want to avoid sending the same query multiple times when the first one is still pending, so you will likely want to use this in combination with a `CoopExecutor` like this: ```php $executor = new CoopExecutor( new TimeoutExecutor( new TcpTransportExecutor($nameserver), 3.0 ) ); ``` > Internally, this class uses PHP's TCP/IP sockets and does not take advantage of [react/socket](https://github.com/reactphp/socket) purely for organizational reasons to avoid a cyclic dependency between the two packages. Higher-level components should take advantage of the Socket component instead of reimplementing this socket logic from scratch. ### SelectiveTransportExecutor The `SelectiveTransportExecutor` class can be used to Send DNS queries over a UDP or TCP/IP stream transport. This class will automatically choose the correct transport protocol to send a DNS query to your DNS server. It will always try to send it over the more efficient UDP transport first. If this query yields a size related issue (truncated messages), it will retry over a streaming TCP/IP transport. For more advanced usages one can utilize this class directly. The following example looks up the `IPv6` address for `reactphp.org`. ```php $executor = new SelectiveTransportExecutor($udpExecutor, $tcpExecutor); $executor->query( new Query($name, Message::TYPE_AAAA, Message::CLASS_IN) )->then(function (Message $message) { foreach ($message->answers as $answer) { echo 'IPv6: ' . $answer->data . PHP_EOL; } }, 'printf'); ``` Note that this executor only implements the logic to select the correct transport for the given DNS query. Implementing the correct transport logic, implementing timeouts and any retry logic is left up to the given executors, see also [`UdpTransportExecutor`](#udptransportexecutor) and [`TcpTransportExecutor`](#tcptransportexecutor) for more details. Note that this executor is entirely async and as such allows you to execute any number of queries concurrently. You should probably limit the number of concurrent queries in your application or you're very likely going to face rate limitations and bans on the resolver end. For many common applications, you may want to avoid sending the same query multiple times when the first one is still pending, so you will likely want to use this in combination with a `CoopExecutor` like this: ```php $executor = new CoopExecutor( new SelectiveTransportExecutor( $datagramExecutor, $streamExecutor ) ); ``` ### HostsFileExecutor Note that the above `UdpTransportExecutor` class always performs an actual DNS query. If you also want to take entries from your hosts file into account, you may use this code: ```php $hosts = \React\Dns\Config\HostsFile::loadFromPathBlocking(); $executor = new UdpTransportExecutor('8.8.8.8:53'); $executor = new HostsFileExecutor($hosts, $executor); $executor->query( new Query('localhost', Message::TYPE_A, Message::CLASS_IN) ); ``` ## Install The recommended way to install this library is [through Composer](https://getcomposer.org/).

This allows consumers to type hint against the interface and third parties to provide alternate implementations. #### get() The `get(string $key, mixed $default = null): PromiseInterface<mixed>` method can be used to retrieve an item from the cache. This method will resolve with the cached value on success or with the given `$default` value when no item can be found or when an error occurs. Similarly, an expired cache item (once the time-to-live is expired) is considered a cache miss. ```php $cache ->get('foo') ->then('var_dump'); ``` This example fetches the value of the key `foo` and passes it to the `var_dump` function. You can use any of the composition provided by [promises](https://github.com/reactphp/promise). #### set() The `set(string $key, mixed $value, ?float $ttl = null): PromiseInterface<bool>` method can be used to store an item in the cache. This method will resolve with `true` on success or `false` when an error occurs. If the cache implementation has to go over the network to store it, it may take a while. The optional `$ttl` parameter sets the maximum time-to-live in seconds for this cache item. If this parameter is omitted (or `null`), the item will stay in the cache for as long as the underlying implementation supports. Trying to access an expired cache item results in a cache miss, see also [`get()`](#get). ```php $cache->set('foo', 'bar', 60); ``` This example eventually sets the value of the key `foo` to `bar`. If it already exists, it is overridden. This interface does not enforce any particular TTL resolution, so special care may have to be taken if you rely on very high precision with millisecond accuracy or below. Cache implementations SHOULD work on a best effort basis and SHOULD provide at least second accuracy unless otherwise noted. Many existing cache implementations are known to provide microsecond or millisecond accuracy, but it's generally not recommended to rely on this high precision. This interface suggests that cache implementations SHOULD use a monotonic time source if available. Given that a monotonic time source is only available as of PHP 7.3 by default, cache implementations MAY fall back to using wall-clock time. While this does not affect many common use cases, this is an important distinction for programs that rely on a high time precision or on systems that are subject to discontinuous time adjustments (time jumps). This means that if you store a cache item with a TTL of 30s and then adjust your system time forward by 20s, the cache item SHOULD still expire in 30s. #### delete() The `delete(string $key): PromiseInterface<bool>` method can be used to delete an item from the cache. This method will resolve with `true` on success or `false` when an error occurs. When no item for `$key` is found in the cache, it also resolves to `true`. If the cache implementation has to go over the network to delete it, it may take a while. ```php $cache->delete('foo'); ``` This example eventually deletes the key `foo` from the cache. As with `set()`, this may not happen instantly and a promise is returned to provide guarantees whether or not the item has been removed from cache. #### getMultiple() The `getMultiple(string[] $keys, mixed $default = null): PromiseInterface<array>` method can be used to retrieve multiple cache items by their unique keys. This method will resolve with an array of cached values on success or with the given `$default` value when an item can not be found or when an error occurs. Similarly, an expired cache item (once the time-to-live is expired) is considered a cache miss. ```php $cache->getMultiple(array('name', 'age'))->then(function (array $values) { $name = $values['name'] ?? 'User'; $age = $values['age'] ?? 'n/a'; echo $name . ' is ' . $age . PHP_EOL; }); ``` This example fetches the cache items for the `name` and `age` keys and prints some example output. You can use any of the composition provided by [promises](https://github.com/reactphp/promise). #### setMultiple() The `setMultiple(array $values, ?float $ttl = null): PromiseInterface<bool>` method can be used to persist a set of key => value pairs in the cache, with an optional TTL. This method will resolve with `true` on success or `false` when an error occurs. If the cache implementation has to go over the network to store it, it may take a while. The optional `$ttl` parameter sets the maximum time-to-live in seconds for these cache items. If this parameter is omitted (or `null`), these items will stay in the cache for as long as the underlying implementation supports. Trying to access an expired cache items results in a cache miss, see also [`getMultiple()`](#getmultiple). ```php $cache->setMultiple(array('foo' => 1, 'bar' => 2), 60); ``` This example eventually sets the list of values - the key `foo` to `1` value and the key `bar` to `2`. If some of the keys already exist, they are overridden. #### deleteMultiple() The `setMultiple(string[] $keys): PromiseInterface<bool>` method can be used to delete multiple cache items in a single operation. This method will resolve with `true` on success or `false` when an error occurs. When no items for `$keys` are found in the cache, it also resolves to `true`. If the cache implementation has to go over the network to delete it, it may take a while. ```php $cache->deleteMultiple(array('foo', 'bar, 'baz')); ``` This example eventually deletes keys `foo`, `bar` and `baz` from the cache. As with `setMultiple()`, this may not happen instantly and a promise is returned to provide guarantees whether or not the item has been removed from cache. #### clear() The `clear(): PromiseInterface<bool>` method can be used to wipe clean the entire cache. This method will resolve with `true` on success or `false` when an error occurs. If the cache implementation has to go over the network to delete it, it may take a while. ```php $cache->clear(); ``` This example eventually deletes all keys from the cache. As with `deleteMultiple()`, this may not happen instantly and a promise is returned to provide guarantees whether or not all the items have been removed from cache. #### has() The `has(string $key): PromiseInterface<bool>` method can be used to determine whether an item is present in the cache. This method will resolve with `true` on success or `false` when no item can be found or when an error occurs. Similarly, an expired cache item (once the time-to-live is expired) is considered a cache miss. ```php $cache ->has('foo') ->then('var_dump'); ``` This example checks if the value of the key `foo` is set in the cache and passes the result to the `var_dump` function. You can use any of the composition provided by [promises](https://github.com/reactphp/promise). NOTE: It is recommended that has() is only to be used for cache warming type purposes and not to be used within your live applications operations for get/set, as this method is subject to a race condition where your has() will return true and immediately after, another script can remove it making the state of your app out of date. ### ArrayCache The `ArrayCache` provides an in-memory implementation of the [`CacheInterface`](#cacheinterface). ```php $cache = new ArrayCache(); $cache->set('foo', 'bar'); ``` Its constructor accepts an optional `?int $limit` parameter to limit the maximum number of entries to store in the LRU cache. If you add more entries to this instance, it will automatically take care of removing the one that was least recently used (LRU). For example, this snippet will overwrite the first value and only store the last two entries: ```php $cache = new ArrayCache(2); $cache->set('foo', '1'); $cache->set('bar', '2'); $cache->set('baz', '3'); ``` This cache implementation is known to rely on wall-clock time to schedule future cache expiration times when using any version before PHP 7.3, because a monotonic time source is only available as of PHP 7.3 (`hrtime()`). While this does not affect many common use cases, this is an important distinction for programs that rely on a high time precision or on systems that are subject to discontinuous time adjustments (time jumps). This means that if you store a cache item with a TTL of 30s on PHP < 7.3 and then adjust your system time forward by 20s, the cache item may expire in 10s. See also [`set()`](#set) for more details. ## Common usage ### Fallback get A common use case of caches is to attempt fetching a cached value and as a fallback retrieve it from the original data source if not found. Here is an example of that: ```php $cache ->get('foo') ->then(function ($result) { if ($result === null) { return getFooFromDb(); } return $result; }) ->then('var_dump'); ``` First an attempt is made to retrieve the value of `foo`. A callback function is registered that will call `getFooFromDb` when the resulting value is null. `getFooFromDb` is a function (can be any PHP callable) that will be called if the key does not exist in the cache. `getFooFromDb` can handle the missing key by returning a promise for the actual value from the database (or any other data source). As a result, this chain will correctly fall back, and provide the value in both cases. ### Fallback get and set To expand on the fallback get example, often you want to set the value on the cache after fetching it from the data source. ```php $cache ->get('foo') ->then(function ($result) { if ($result === null) { return $this->getAndCacheFooFromDb(); } return $result; }) ->then('var_dump'); public function getAndCacheFooFromDb() { return $this->db ->get('foo') ->then(array($this, 'cacheFooFromDb')); } public function cacheFooFromDb($foo) { $this->cache->set('foo', $foo); return $foo; } ``` By using chaining you can easily conditionally cache the value if it is fetched from the database. ## Install The recommended way to install this library is [through Composer](https://getcomposer.org).

Build up your application through simple interfaces and re-use your application without changing any of its code just by combining different components. ## Requirements Shell access is required and root access is recommended. To avoid proxy/firewall blockage it's recommended WebSockets are requested on port 80 or 443 (SSL), which requires root access. In order to do this, along with your sync web stack, you can either use a reverse proxy or two separate machines. You can find more details in the [server conf docs](http://socketo.me/docs/deploy#server_configuration). ### Documentation User and API documentation is available on Ratchet's website: http://socketo.me See https://github.com/cboden/Ratchet-examples for some out-of-the-box working demos using Ratchet. Need help? Have a question? Want to provide feedback?
