使用php的swoole架構，實現高效能長串連websocket__web

swoole的官網請見:http://www.swoole.com/
swoole-git:https://github.com/swoole/swoole-src 一.伺服器端： 1. 編輯server.php檔案內容如下：

<?php$reqs=array(); //保持用戶端的長串連在這個數組裡$serv = new swoole_websocket_server("192.168.2.115", 9502);//如下可以設定多連接埠監聽//$server = new swoole_websocket_server("0.0.0.0", 9501, SWOOLE_BASE);//$server->addlistener('0.0.0.0', 9502, SWOOLE_SOCK_UDP);//$server->set(['worker_num' => 4]);$serv->on('Open', function($server, $req) {    global $reqs;    $reqs[]=$req->fd;    echo "connection open: ".$req->fd."\n";    var_dump(count($reqs));//輸出長串連數});$serv->on('Message', function($server, $frame) {    global $reqs;    echo "message: ".$frame->data."\n";    foreach($reqs as $fd){            $server->push($fd, $frame->data);    }});$serv->on('Close', function($server, $fd) {    echo "connection close: ".$fd."\n";});$serv->start();

2. 啟動上面實現的websocket服務代碼

[songaimin@localhost Tests]$/usr/bin/php server.php

用戶端-同事開啟兩個瀏覽器類比多client： 3. 在瀏覽器console裡運行:

var wsl= 'ws://192.168.2.115:9502'ws = new WebSocket(wsl);//建立立一個串連//如下指定事件處理 ws.onopen = function(){ws.send('Test!'); };  ws.onmessage = function(evt){console.log(evt.data);/*ws.close();*/};  ws.onclose = function(evt){console.log('WebSocketClosed!');};  ws.onerror = function(evt){console.log('WebSocketError!');}; 

4. 在任意瀏覽器console裏手動執行：

ws.send(888);//看每個瀏覽器的內容console輸出應該是一樣的就實驗在成功了ws.close();//關閉串連
