socket；ios客戶端與php服務端交互(補充html5+python服務端+ios客戶端)

這幾天工程少了靜下心來玩玩WebSocket，發現還是挺有意思的，目前只是做做測試，有待研究更深入的東西

當然ios我引入了AsyncSocket庫作為我的socket庫，有興趣的朋友可以谷歌一下這個東西，挺實用的

（補充）近期還玩了下基於python，html5和ios端的WebSocket，頗有感悟，大家有興趣可以去谷歌下RockSocket，簡單易用而且方便，是個很好的HTML5和ios端相互交流的socket框架。

php sever端：

<?php
set_time_limit(600);//設置10分鍾的超時時間，避免資源浪費
$ip = '127.0.0.1';//配置服務端IP地址
$port = 9196;//服務端端口
if(($sock = socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0) {//建立一個套接字
    echo "socket_create() failed:".socket_strerror($sock)."\n";}
if(($ret = socket_bind($sock,$ip,$port)) < 0) {//為套接字設置IP和端口
    echo "socket_bind() failed:".socket_strerror($ret)."\n";}
if(($ret = socket_listen($sock,4)) < 0) {//監聽端口
    echo "socket_listen() failed:".socket_strerror($ret)."\n";}
$count = 0;
do {
    if (($msgsock = socket_accept($sock)) < 0) {//等待並接受客戶端連接
        echo "socket_accept() failed: reason: " . socket_strerror($msgsock) . "\n";
        break;}
else{//發送信息到客戶端
        $msg ="Shura so good！\n";
        socket_write($msgsock, $msg, strlen($msg));
        echo "測試成功\n";
        $buf = socket_read($msgsock,9999);
        $talkback = "收到的信息:$buf\n";
        echo $talkback;
        if(++$count >= 5){break;};}//重試5次后，自動關閉套接字
    socket_close($msgsock);
} while (true);
socket_close($sock);//關閉套接字
?>
