workerman是什么？

Workerman是一个异步事件驱动的PHP框架，具有高性能，可轻松构建快速，可扩展的网络应用程序。支持HTTP，Websocket，SSL和其他自定义协议。支持libevent，HHVM，ReactPHP。

要求

PHP 5.3或更高版本
兼容POSIX的操作系统（Linux，OSX，BSD）
用于PHP的POSIX和PCNTL扩展

安装

1	`composer` `require` `workerman/workerman`

基本用法

websocket服务器

<?php
require_once __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;
 
// 创建一个Websocket服务器
$ws_worker = new Worker("websocket://0.0.0.0:2346");
 
$ws_worker->count = 4;
 
// 在新连接到来时发出
$ws_worker->onConnect = function($connection)
{
    echo "New connection\n";
 };
 
// 接收数据时发出
$ws_worker->onMessage = function($connection, $data)
{
    // Send hello $data
    $connection->send('hello ' . $data);
};
 
// 连接关闭时发出
$ws_worker->onClose = function($connection)
{
    echo "Connection closed\n";
};
 
// 运行worker
Worker::runAll();

http服务器

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;
 
// 接收数据时发出
$http_worker->onMessage = function($connection, $data)
{
    //$_GET、$_POST、$_COOKIE、$_SESSION、$_SERVER、$_FILES都是可用的
    var_dump($_GET, $_POST, $_COOKIE, $_SESSION, $_SERVER, $_FILES);
    // 发送数据给客户端
    $connection->send("hello world \n");
};
 
// 运行所有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服务器

require_once __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;
 
// #### 创建socket并监听1234端口 ####
$tcp_worker = new Worker("tcp://0.0.0.0:1234");
 
$tcp_worker->count = 4;
 
//在新连接到来时发出
$tcp_worker->onConnect = function($connection)
{
    echo "New Connection\n";
};
 
// 接收数据时发出
$tcp_worker->onMessage = function($connection, $data)
{
    // 发送数据给客户端
    $connection->send("hello $data \n");
};
 
// 在新连接到来时发出
$tcp_worker->onClose = function($connection)
{
    echo "Connection closed\n";
};
 
Worker::runAll();

启用SSL

<?php
require_once __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;
 
// SSL环境
$context = array(
    'ssl' => array(
        'local_cert'  => '/your/path/of/server.pem',
        'local_pk'    => '/your/path/of/server.key',
        'verify_peer' => false,
    )
);
 
// 创建一个带有ssl的Websocket服务器。
$ws_worker = new Worker("websocket://0.0.0.0:2346", $context);
 
// 启用SSL。WebSocket+SSL意味着安全的WebSocket (wss://)。
//类似的Https方法等等。
$ws_worker->transport = 'ssl';
 
$ws_worker->onMessage = function($connection, $data)
{
    // 发送hello $data
    $connection->send('hello ' . $data);
};
 
Worker::runAll();

namespace Protocols;
/**
 * 用户定义的协议
*格式文本+“\ n”
 */
class MyTextProtocol
{
    public static function input($recv_buffer)
    {
        // 找到“\n”第一个出现的位置
        $pos = strpos($recv_buffer, "\n");
        // 不是一个完整的package。返回0，因为package的长度无法计算
        if($pos === false)
        {
            return 0;
        }
        // 返回package的长度
        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)
{
    // 发送数据给客户端
    $connection->send("hello world \n");
};
 
$text_worker->onClose = function($connection)
{
    echo "Connection closed\n";
};
 
// 运行所有workers
Worker::runAll();

计时器

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";
        }
    );
};
 
//运行
Worker::runAll();

require_once __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;
use Workerman\Connection\AsyncTcpConnection;
 
$worker = new Worker();
$worker->onWorkerStart = function()

    $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";
