使用swoole擴展php websocket示例

 WebSocket規范的目標是在浏覽器中實現和服務器端雙向通信。雙向通信可以拓展浏覽器上的應用類型，如果你想要用PHP來寫websocket應用，那swoole_framework一定是最好的選擇,需要的朋友可以參考下

 代碼如下: <?php define('DEBUG', 'on'); define("WEBPATH", str_replace("","/", __DIR__)); require __DIR__ . '/../libs/lib_config.php';   class WebSocket extends SwooleNetworkProtocolWebSocket {     /**      * 下線時，通知所有人      */     function onClose($serv, $client_id, $from_id)     {         //將下線消息發送給所有人         //$this->log("onOffline: " . $client_id);         //$this->broadcast($client_id, "onOffline: " . $client_id);         parent::onClose($serv, $client_id, $from_id);     }       /**      * 接收到消息時      * @see WSProtocol::onMessage()      */     function onMessage($client_id, $ws)     {         $this->log("onMessage: ".$client_id.' = '.$ws['message']);         $this->send($client_id, "Server: ".$ws['message']);   //$this->broadcast($client_id, $ws['message']);     }       function broadcast($client_id, $msg)     {         foreach ($this->connections as $clid => $info)         {             if ($client_id != $clid)             {                 $this->send($clid, $msg);             }         }     } }     $AppSvr = new WebSocket(); $AppSvr->loadSetting(__DIR__."/swoole.ini"); //加載配置文件 $AppSvr->setLogger(new SwooleLogEchoLog(true)); //Logger   $server = new SwooleNetworkServer('0.0.0.0', 9503); $server->setProtocol($AppSvr); //$server->daemonize(); //作為守護進程 $server->run(array('worker_num' =>4));
