# Workerman [](https://gitter.im/walkor/Workerman?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=body_badge) ## What is it Workerman is an asynchronous event driven PHP framework with high performance for easily building fast, scalable network applications.Supports HTTP, Websocket and other custom protocols. Supports libevent, HHVM, [ReactPHP](https://github.com/reactphp/react). ## Requires PHP 5.3 or Higher A POSIX compatible operating system (Linux, OSX, BSD) POSIX and PCNTL extensions for PHP ## Installation ``` composer require workerman/workerman ``` ## Basic Usage ### A websocket server ```php <?php require_once __DIR__ . '/vendor/autoload.php'; use Workerman\Worker; // Create a Websocket server $ws_worker = new Worker("websocket://0.0.0.0:2346"); // 4 processes $ws_worker->count = 4; // 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 require_once __DIR__ . '/vendor/autoload.php'; use Workerman\Worker; // #### 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, $data) { // $_GET, $_POST, $_COOKIE, $_SESSION, $_SERVER, $_FILES are available var_dump($_GET, $_POST, $_COOKIE, $_SESSION, $_SERVER, $_FILES); // send data to client $connection->send("hello world \n"); }; // run all workers Worker::runAll(); ``` ### A WebServer ```php require_once __DIR__ . '/vendor/autoload.php'; use Workerman\WebServer; use Workerman\Worker; // WebServer $web = new WebServer("http://0.0.0.0:80"); // 4 processes $web->count = 4; // Set the root of domains $web->addRoot('www.your_domain.com', '/your/path/Web'); $web->addRoot('www.another_domain.com', '/another/path/Web'); // run all workers Worker::runAll(); ``` ### A tcp server ```php require_once __DIR__ . '/vendor/autoload.php'; use Workerman\Worker; // #### 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 new connection come $tcp_worker->onClose = function($connection) { echo "Connection closed\n"; }; Worker::runAll(); ``` ### Custom protocol Protocols/MyTextProtocol.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 require_once __DIR__ . '/vendor/autoload.php'; use Workerman\Worker; // #### 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 require_once __DIR__ . '/vendor/autoload.php'; use Workerman\Worker; use Workerman\Lib\Timer; $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 require_once __DIR__ . '/vendor/autoload.php'; use Workerman\Worker; use Workerman\Connection\AsyncTcpConnection; $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(); ``` ### Async Mysql of ReactPHP ``` composer require react/mysql ``` ```php <?php require_once __DIR__ . '/vendor/autoload.php'; use Workerman\Worker; $worker = new Worker('tcp://0.0.0.0:6161'); $worker->onWorkerStart = function() { global $mysql; $loop = Worker::getEventLoop(); $mysql = new React\MySQL\Connection($loop, array( 'host' => '127.0.0.1', 'dbname' => 'dbname', 'user' => 'user', 'passwd' => 'passwd', )); $mysql->on('error', function($e){ echo $e; }); $mysql->connect(function ($e) { if($e) { echo $e; } else { echo "connect success\n"; } }); }; $worker->onMessage = function($connection, $data) { global $mysql; $mysql->query('show databases' /*trim($data)*/, function ($command, $mysql) use ($connection) { if ($command->hasError()) { $error = $command->getError(); } else { $results = $command->resultRows; $fields = $command->resultFields; $connection->send(json_encode($results)); } }); }; Worker::runAll(); ``` ### Async Redis of ReactPHP ``` composer require clue/redis-react ``` ```php <?php require_once __DIR__ . '/vendor/autoload.php'; use Clue\React\Redis\Factory; use Clue\React\Redis\Client; use Workerman\Worker; $worker = new Worker('tcp://0.0.0.0:6161'); $worker->onWorkerStart = function() { global $factory; $loop = Worker::getEventLoop(); $factory = new Factory($loop); }; $worker->onMessage = function($connection, $data) { global $factory; $factory->createClient('localhost:6379')->then(function (Client $client) use ($connection) { $client->set('greeting', 'Hello world'); $client->append('greeting', '!'); $client->get('greeting')->then(function ($greeting) use ($connection){ // Hello world! echo $greeting . PHP_EOL; $connection->send($greeting); }); $client->incr('invocation')->then(function ($n) use ($connection){ echo 'This is invocation #' . $n . PHP_EOL; $connection->send($n); }); }); }; Worker::runAll(); ``` ### Aysnc dns of ReactPHP ``` composer require react/dns ``` ```php require_once __DIR__ . '/vendor/autoload.php'; use Workerman\Worker; $worker = new Worker('tcp://0.0.0.0:6161'); $worker->onWorkerStart = function() { global $dns; // Get event-loop. $loop = Worker::getEventLoop(); $factory = new React\Dns\Resolver\Factory(); $dns = $factory->create('8.8.8.8', $loop); }; $worker->onMessage = function($conn
