Workerman

What is it

Workerman is an asynchronous event-driven PHP framework with high performance to build fast and scalable network applications. Workerman supports HTTP, Websocket, SSL and other custom protocols. Workerman supports event extension.

Requires

PHP 5.3 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

use Workerman\Worker;

require_once __DIR__ . '/vendor/autoload.php';

// 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

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

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();

Enable SSL

<?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

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";
    }
}

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

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...)

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();
