workerman是什么？

Workerman是一個異步事件驅動的PHP框架，具有高性能，可輕松構建快速，可擴展的網絡應用程序。支持HTTP，Websocket，SSL和其他自定義協議。支持libevent，HHVM，ReactPHP。

要求:

PHP 5.3或更高版本

兼容POSIX的操作系統（Linux，OSX，BSD）

用于PHP的POSIX和PCNTL擴展

安裝:

composer require workerman/workerman

基本用法:

websocket服務器

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

use Workerman/Worker;

// 創建一個Websocket服務器

$ws_worker = new Worker("websocket://0.0.0.0:2346");

$ws_worker->count = 4;

// 在新連接到來時發出

$ws_worker->onConnect = function($connection)

{

    echo "New connection/n";

};

// 接收數據時發出

$ws_worker->onMessage = function($connection, $data)

{

    // Send hello $data

    $connection->send('hello ' . $data);

};

// 連接關閉時發出

$ws_worker->onClose = function($connection)

{

    echo "Connection closed/n";

};

// 運行worker

Worker::runAll();

http服務器

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

use Workerman/Worker;

// #### http worker ####

$http_worker = new Worker("http://0.0.0.0:2345");

$http_worker->count = 4;

// 接收數據時發出

$http_worker->onMessage = function($connection, $data)

{

    //$_GET、$_POST、$_COOKIE、$_SESSION、$_SERVER、$_FILES都是可用的

    var_dump($_GET, $_POST, $_COOKIE, $_SESSION, $_SERVER, $_FILES);

    // 發送數據給客戶端

    $connection->send("hello world /n");

};

// 運行所有workers

Worker::runAll();

WebServer

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

use Workerman/WebServer;

use Workerman/Worker;

// WebServer

$web = new WebServer("http://0.0.0.0:80");

$web->count = 4;

$web->addRoot('www.your_domain.com', '/your/path/Web');

$web->addRoot('www.another_domain.com', '/another/path/Web');

Worker::runAll();

TCP服務器

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

use Workerman/Worker;

// #### 創建socket并監聽1234端口 ####

$tcp_worker = new Worker("tcp://0.0.0.0:1234");

$tcp_worker->count = 4;

//在新連接到來時發出

$tcp_worker->onConnect = function($connection)

{

    echo "New Connection/n";

};

// 接收數據時發出

$tcp_worker->onMessage = function($connection, $data)

{

    // 發送數據給客戶端

    $connection->send("hello $data /n");

};

// 在新連接到來時發出

$tcp_worker->onClose = function($connection)

{

    echo "Connection closed/n";

};

Worker::runAll();

啟用SSL

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

use Workerman/Worker;

// SSL環境

$context = array(

    'ssl' => array(

        'local_cert'  => '/your/path/of/server.pem',

        'local_pk'    => '/your/path/of/server.key',

        'verify_peer' => false,

    )

);

// 創建一個帶有ssl的Websocket服務器。

$ws_worker = new Worker("websocket://0.0.0.0:2346", $context);



// 啟用SSL。WebSocket+SSL意味著安全的WebSocket (wss://)。

//類似的Https方法等等。

$ws_worker->transport = 'ssl';



$ws_worker->onMessage = function($connection, $data)

{

    // 發送hello $data

    $connection->send('hello ' . $data);

};

Worker::runAll();

自定義協議

Protocols/MyTextProtocol.php

namespace Protocols;

/**

* 用戶定義的協議

*格式文本+“/ n”

*/

class MyTextProtocol

{

    public static function input($recv_buffer)

    {

        // 找到“/n”第一個出現的位置

        $pos = strpos($recv_buffer, "/n");

        // 不是一個完整的package。返回0，因為package的長度無法計算

        if($pos === false)

        {

            return 0;

        }

        // 返回package的長度

        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)

{

    // 發送數據給客戶端

    $connection->send("hello world /n");

};

$text_worker->onClose = function($connection)

{

    echo "Connection closed/n";

};

// 運行所有workers

Worker::runAll();

計時器

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

use Workerman/Worker;

use Workerman/Lib/Timer;

$task = new Worker();

$task->onWorkerStart = function($task)

{

    // 2.5秒

    $time_interval = 2.5;

    $timer_id = Timer::add($time_interval,

        function()

        {

            echo "Timer run/n";

        }

    );

};

//運行

Worker::runAll();

AsyncTcpConnection（tcp / ws / text / frame等...）

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

use Workerman/Worker;

use Workerman/Connection/AsyncTcpConnection;

$worker = new Worker();

$worker->onWorkerStart = function()

{

    //客戶端Websocket協議。

    $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();
