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

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');

// 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 = [
    'ssl' => [
        '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();

Use HTTP proxy

<?php

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

use Workerman\Connection\AsyncTcpConnection;
$worker = new \Workerman\Worker();
$worker->onWorkerStart = function($worker){
    echo '开始链接' . PHP_EOL;
    $url = 'ws://stream.binance.com:9443/ws';
    $con = new AsyncTcpConnection($url);
    $con->transport = 'ssl';
//    $con->proxySocks5 = '127.0.0.1:1080';
    $con->proxyHttp = '127.0.0.1:25378';

    $con->onConnect = function(AsyncTcpConnection $con) {
        $ww = [
            'id' => 1,
            'method' => 'SUBSCRIBE',
            'params' => [
                "btcusdt@aggTrade",
                "btcusdt@depth"
            ]
        ];
        echo '链接成功';
        $con->send(json_encode($ww));
        echo 'ok';
    };

    $con->onMessage = function(AsyncTcpConnection $con, $data) {
        echo $data;
    };

    $con->onClose = function (AsyncTcpConnection $con) {
        echo 'onClose' . PHP_EOL;
    };

    $con->onError = function (AsyncTcpConnection $con, $code, $msg) {
        echo "error [ $code ] $msg\n";
    };

    $con->connect();
};
\Workerman\Worker::runAll();

Use Socks5 proxy

<?php

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

use Workerman\Connection\AsyncTcpConnection;
$worker = new \Workerman\Worker();
$worker->onWorkerStart = function($worker){
    echo '开始链接' . PHP_EOL;
    $url = 'ws://stream.binance.com:9443/ws';
    $con = new AsyncTcpConnection($url);
    $con->transport = 'ssl';
    $con->proxySocks5 = '127.0.0.1:1080';
//    $con->proxyHttp = '127.0.0.1:25378';

    $con->onConnect = function(AsyncTcpConnection $con) {
        $ww = [
            'id' => 1,
            'method' => 'SUBSCRIBE',
            'params' => [
                "btcusdt@aggTrade",
                "btcusdt@depth"
            ]
        ];
        echo '链接成功';
        $con->send(json_encode($ww));
        echo 'ok';
    };

    $con->onMessage = function(AsyncTcpConnection $con, $data) {
        echo $data;
    };

    $con->onClose = function (AsyncTcpConnection $con) {
        echo 'onClose' . PHP_EOL;
    };

    $con->onError = function (AsyncTcpConnection $con, $code, $msg) {
        echo "error [ $code ] $msg\n";
    };

    $con->connect();
};
\Workerman\Worker::runAll();

proxy supports TLS1.3, no Sniproxy channel
