Workerman 3.0

Documentation:http://doc3.workerman.net

What is it

Workerman is a library for event-driven programming in PHP. It has a huge number of features. Each worker is able to handle thousands of connections.

Usage

A tcp server

test.php

require_once './Workerman/Autoloader.php';
use Workerman\Worker;

// #### create socket and listen 1234 port ####
$tcp_worker = new Worker("tcp://0.0.0.0:1234");
//create 4 hello_worker processes
$tcp_worker->count = 4;
// when client send data to 1234 port
$tcp_worker->onMessage = function($connection, $data)
{
    // send data to client
    $connection->send("hello $data \n");
};

Worker::runAll();

A http server

test.php

require_once './Workerman/Autoloader.php';
use Workerman\Worker;

// #### http worker ####
$http_worker = new Worker("http://0.0.0.0:2345");
$http_worker->count = 4;
$http_worker->onMessage = function($connection, $data)
{
    // send data to client
    $connection->send("hello world \n");
};

// run all workers
Worker::runAll();

A websocket server

test.php

require_once './Workerman/Autoloader.php';
use Workerman\Worker
// #### websocket worker ####
$ws_worker = new Worker("websocket://0.0.0.0:5678");
$ws_worker->onMessage =  function($connection, $data)
{
    // send data to client
    $connection->send("hello world \n");
};

// run all workers
Worker::runAll();

User defined protocol

Protocols/MyTextProtocol.php

/**
 * 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";
    }
}

test.php

require_once './Workerman/Autoloader.php';
use Workerman\Worker
// #### MyTextProtocol worker ####
$text_worker = new Worker("MyTextProtocol://0.0.0.0:5678");
$text_worker->onMessage =  function($connection, $data)
{
    // send data to client
    $connection->send("hello world \n");
};

// run all workers
Worker::runAll();

A WebServer

test.php

require_once './Workerman/Autoloader.php';
use \Workerman\WebServer;
// WebServer
$web = new WebServer("http://0.0.0.0:8686");
$web->count = 2;
$web->addRoot('www.your_domain.com', __DIR__.'/Web');
// run all workers
Worker::runAll();

Timer

test.php

require_once './Workerman/Autoloader.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();
