Swoole主要功能： PHP语言的异步、并行、高性能网络通信框架，使用纯C语言编写，提供了PHP语言的异步多线程服务器，异步TCP/UDP网络客户端，异步MySQL，数据库连接池，AsyncTask，消息队列，毫秒定时器，异步文件读写，异步DNS查询。
WebSocket Server
$serv = new swoole_websocket_server("127.0.0.1", 9502);
$serv->on('Open', function($server, $req)
{
echo "connection open: ".$req->fd;
});
$serv->on('Message', function($server, $frame)
{
echo "message: ".$frame->data;
$server->push($frame->fd, json_encode(["hello", "world"]));
});
$serv->on('Close', function($server, $fd)
{ echo "connection close: ".$fd;
});
$serv->start();TCP Server
$serv = new swoole_server("127.0.0.1", 9501);
$serv->set(array(
'worker_num' => 8, //工作进程数量
'daemonize' => true, //是否作为守护进程
));
$serv->on('connect', function ($serv, $fd){
echo "Client:Connect.\n";
});
$serv->on('receive', function ($serv, $fd, $from_id, $data) {
$serv->send($fd, 'Swoole: '.$data);
$serv->close($fd);
});
$serv->on('close', function ($serv, $fd) {
echo "Client: Close.\n";
});
$serv->start();TCP Client
$client = new swoole_client(SWOOLE_SOCK_TCP, SWOOLE_SOCK_ASYNC);
//设置事件回调函数
$client->on("connect", function($cli) {
$cli->send("hello world\n");
});
$client->on("receive", function($cli, $data){
echo "Received: ".$data."\n";
});
$client->on("error", function($cli){
echo "Connect failed\n";
});
$client->on("close", function($cli){
echo "Connection close\n";
});
//发起网络连接
$client->connect('127.0.0.1', 9501, 0.5);自己工作中用到的就这三个，具体的配置和更多的功能，可以访问swoole网站： http://www.swoole.com/
注明： Apache 配置swoole的时候，记得在两个配置文件php.ini 中，加入 swoole.so 否则会导致部分访问无效
