Workerman supports HTTP, Websocket, SSL and other custom protocols. Workerman supports event extension. ## Requires PHP 5.4 or Higher A POSIX compatible operating system (Linux, OSX, BSD) POSIX and PCNTL extensions required Event extension recommended for better performance ## Installation ``` composer require workerman/workerman ``` ## Basic Usage ### A websocket server ```php <?php use Workerman\Worker; require_once __DIR__ . '/vendor/autoload.php'; // Create a Websocket server $ws_worker = new Worker('websocket://0.0.0.0:2346'); // Emitted when new connection come $ws_worker->onConnect = function ($connection) { echo "New connection\n"; }; // Emitted when data received $ws_worker->onMessage = function ($connection, $data) { // Send hello $data $connection->send('Hello ' . $data); }; // Emitted when connection closed $ws_worker->onClose = function ($connection) { echo "Connection closed\n"; }; // Run worker Worker::runAll(); ``` ### An http server ```php <?php use Workerman\Worker; require_once __DIR__ . '/vendor/autoload.php'; // #### http worker #### $http_worker = new Worker('http://0.0.0.0:2345'); // 4 processes $http_worker->count = 4; // Emitted when data received $http_worker->onMessage = function ($connection, $request) { //$request->get(); //$request->post(); //$request->header(); //$request->cookie(); //$request->session(); //$request->uri(); //$request->path(); //$request->method(); // Send data to client $connection->send("Hello World"); }; // Run all workers Worker::runAll(); ``` ### A tcp server ```php <?php use Workerman\Worker; require_once __DIR__ . '/vendor/autoload.php'; // #### create socket and listen 1234 port #### $tcp_worker = new Worker('tcp://0.0.0.0:1234'); // 4 processes $tcp_worker->count = 4; // Emitted when new connection come $tcp_worker->onConnect = function ($connection) { echo "New Connection\n"; }; // Emitted when data received $tcp_worker->onMessage = function ($connection, $data) { // Send data to client $connection->send("Hello $data \n"); }; // Emitted when connection is closed $tcp_worker->onClose = function ($connection) { echo "Connection closed\n"; }; Worker::runAll(); ``` ### A udp server ```php <?php use Workerman\Worker; require_once __DIR__ . '/vendor/autoload.php'; $worker = new Worker('udp://0.0.0.0:1234'); // 4 processes $tcp_worker->count = 4; // Emitted when data received $worker->onMessage = function($connection, $data) { $connection->send($data); }; Worker::runAll(); ``` ### Enable SSL ```php <?php use Workerman\Worker; require_once __DIR__ . '/vendor/autoload.php'; // SSL context. $context = array( 'ssl' => array( 'local_cert' => '/your/path/of/server.pem', 'local_pk' => '/your/path/of/server.key', 'verify_peer' => false, ) ); // Create a Websocket server with ssl context. $ws_worker = new Worker('websocket://0.0.0.0:2346', $context); // Enable SSL. WebSocket+SSL means that Secure WebSocket (wss://). // The similar approaches for Https etc. $ws_worker->transport = 'ssl'; $ws_worker->onMessage = function ($connection, $data) { // Send hello $data $connection->send('Hello ' . $data); }; Worker::runAll(); ``` ### Custom protocol Protocols/MyTextProtocol.php ```php <?php namespace Protocols; /** * User defined protocol * Format Text+"\n" */ class MyTextProtocol { public static function input($recv_buffer) { // Find the position of the first occurrence of "\n" $pos = strpos($recv_buffer, "\n"); // Not a complete package. Return 0 because the length of package can not be calculated if ($pos === false) { return 0; } // Return length of the package return $pos+1; } public static function decode($recv_buffer) { return trim($recv_buffer); } public static function encode($data) { return $data . "\n"; } } ``` ```php <?php use Workerman\Worker; require_once __DIR__ . '/vendor/autoload.php'; // #### MyTextProtocol worker #### $text_worker = new Worker('MyTextProtocol://0.0.0.0:5678'); $text_worker->onConnect = function ($connection) { echo "New connection\n"; }; $text_worker->onMessage = function ($connection, $data) { // Send data to client $connection->send("Hello world\n"); }; $text_worker->onClose = function ($connection) { echo "Connection closed\n"; }; // Run all workers Worker::runAll(); ``` ### Timer ```php <?php use Workerman\Worker; use Workerman\Timer; require_once __DIR__ . '/vendor/autoload.php'; $task = new Worker(); $task->onWorkerStart = function ($task) { // 2.5 seconds $time_interval = 2.5; $timer_id = Timer::add($time_interval, function () { echo "Timer run\n"; }); }; // Run all workers Worker::runAll(); ``` ### AsyncTcpConnection (tcp/ws/text/frame etc...) ```php <?php use Workerman\Worker; use Workerman\Connection\AsyncTcpConnection; require_once __DIR__ . '/vendor/autoload.php'; $worker = new Worker(); $worker->onWorkerStart = function () { // Websocket protocol for client. $ws_connection = new AsyncTcpConnection('ws://echo.websocket.org:80'); $ws_connection->onConnect = function ($connection) { $connection->send('Hello'); }; $ws_connection->onMessage = function ($connection, $data) { echo "Recv: $data\n"; }; $ws_connection->onError = function ($connection, $code, $msg) { echo "Error: $msg\n"; }; $ws_connection->onClose = function ($connection) { echo "Connection closed\n"; }; $ws_connection->connect(); }; Worker::runAll(); ``` ## Available commands ```php start.php start ``` ```php start.php start -d ```  ```php start.php status ```  ```php start.php connections``` ```php start.php stop ``` ```php start.php restart ``` ```php start.php reload ``` ## Documentation 中文主页:[http://www.workerman.net](https://www.workerman.net) 中文文档: [https://www.workerman.net/doc/workerman](https://www.workerman.net/doc/workerman) Documentation:[https://github.com/walkor/workerman-manual](https://github.com/walkor/workerman-manual/blob/master/english/SUMMARY.md) # Benchmarks https://www.techempower.com/benchmarks/#section=data-r20&hw=ph&test=db&l=yyku7z-e7&a=2  ## Sponsors [opencollective.com/walkor](https://opencollective.com/walkor) [patreon.com/walkor](https://patreon.com/walkor) ## Donate <a href="https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=UQGGS9UB35WWG"><img src="http://donate.workerman.net/img/donate.png"></a> ## Other links with workerman [webman](https://github.com/walkor/webman) [PHPSocket.IO](
