swoole-1.7.9 增加了内置的websocket服务器支持，通过几行PHP代码就可以写出一个异步非阻塞多进程的WebSocket服务器。

swoole_websocket_server 继承自 swoole_http_server，如果设置了onRequest回调，websocket服务器也可以同时作为http服务器。

$server = new swoole_websocket_server("0.0.0.0", 9501);

$server->on('open', function (swoole_websocket_server $server, $request) {
    echo "server: handshake success with fd{$request->fd}n";
});

$server->on('message', function (swoole_websocket_server $server, $frame) {
    echo "receive from {$frame->fd}:{$frame->data},opcode:{$frame->opcode},fin:{$frame->finish}n";
    $server->push($frame->fd, "this is server");
});

$server->on('close', function ($ser, $fd) {
    echo "client {$fd} closedn";
});

$server->start();
