php使用socket編程樣本

 這篇文章主要介紹了php使用socket編程的樣本，大家參考使用吧

2個php測試檔案server.php 代碼如下:<?php//phpinfo();//確保在串連用戶端時不會逾時set_time_limit(0); $ip = '127.0.0.1';$port = 1935; /* +------------------------------- *    @socket通訊整個過程 +------------------------------- *    @socket_create *    @socket_bind *    @socket_listen *    @socket_accept *    @socket_read *    @socket_write *    @socket_close +-------------------------------- */ /*----------------    以下操作都是手冊上的    -------------------*/if(($sock = socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0) {    echo "socket_create() 失敗的原因是:".socket_strerror($sock)."n";} if(($ret = socket_bind($sock,$ip,$port)) < 0) {    echo "socket_bind() 失敗的原因是:".socket_strerror($ret)."n";} if(($ret = socket_listen($sock,4)) < 0) {    echo "socket_listen() 失敗的原因是:".socket_strerror($ret)."n";} $count = 0; do {    if (($msgsock = socket_accept($sock)) < 0) {        echo "socket_accept() failed: reason: " . socket_strerror($msgsock) . "n";        break;    } else {         //發到用戶端        $msg ="測試成功！n";        socket_write($msgsock, $msg, strlen($msg));         echo "測試成功了啊n";        $buf = socket_read($msgsock,8192);                 $talkback = "收到的資訊:$bufn";        echo $talkback;         if(++$count >= 5){            break;        };         }    //echo $buf;    socket_close($msgsock); } while (true); socket_close($sock);?>    client.php代碼如下:<?phperror_reporting(E_ALL);set_time_limit(0);echo "<h2>TCP/IP Connection</h2>n"; $port = 1935;$ip = "127.0.0.1"; /* +------------------------------- *    @socket串連整個過程 +------------------------------- *    @socket_create *    @socket_connect *    @socket_write *    @socket_read *    @socket_close +-------------------------------- */ $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);if ($socket < 0) {    echo "socket_create() failed: reason: " . socket_strerror($socket) .
