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
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

{
echo "Connection closed\n";
};

'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);
};

// 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';

{
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

}
);
};
//运行
