Workerman

What is it

Workerman is an asynchronous event driven PHP framework with high performance for easily building fast, scalable network applications. Supports HTTP, Websocket, SSL and other custom protocols. Supports libevent, HHVM , ReactPHP.

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
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

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

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

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();

Enable SSL

<?php
require_once __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;

// 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";
    }
}

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
