服务端：

<?php//确保在连接客户端时不会超时set_time_limit(0);$ip = '127.0.0.1';$port = 1234;/* +------------------------------- *    @socket通信整个过程 +------------------------------- *    @socket_create *    @socket_bind *    @socket_listen *    @socket_accept *    @socket_read *    @socket_write *    @socket_close +-------------------------------- *//*----------------    以下操作都是手册上的    -------------------*/if(($sock = socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0) {    echo "socket_create() 失败的原因是:".socket_strerror($sock)."\n";}if(($ret = socket_bind($sock,$ip,$port)) < 0) {    echo "socket_bind() 失败的原因是:".socket_strerror($ret)."\n";}if(($ret = socket_listen($sock,4)) < 0) {    echo "socket_listen() 失败的原因是:".socket_strerror($ret)."\n";}var_dump($sock);$changes=array($sock);$write=NULL;$except=NULL;socket_select($changes,$write,$except,NULL);//var_dump($changes);$sock=$changes[0];$count = 0;    if (($msgsock = socket_accept($sock)) < 0) {        echo "socket_accept() failed: reason: " . socket_strerror($msgsock) . "\n";        break;    } else {                //发到客户端        $msg ="测试成功,服务端发！\n";        socket_write($msgsock, $msg, strlen($msg));                echo "测试成功了啊\n";        $buf = socket_read($msgsock,8192);                        $talkback = "收到的信息:$buf\n";        echo $talkback;                if(++$count >= 5){            break;        };                }    //echo $buf;    socket_close($msgsock);socket_close($sock);?>

客户端：

<?phperror_reporting(E_ALL);set_time_limit(0);echo "<h2>TCP/IP Connection</h2>\n";$port = 1234;$ip = "127.0.0.1";/* +------------------------------- *    @socket连接整个过程 +------------------------------- *    @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($socket) . "\n";}else {    echo "OK.\n";}echo "试图连接 '$ip' 端口 '$port'...\n";$result = socket_connect($socket, $ip, $port);if ($result < 0) {    echo "socket_connect() failed.\nReason: ($result) " . socket_strerror($result) . "\n";}else {    echo "连接OK\n";}$in = "Ho\r\n";$in .= "first blood\r\n";$out = '';if(!socket_write($socket, $in, strlen($in))) {    echo "socket_write() failed: reason: " . socket_strerror($socket) . "\n";}else {    echo "发送到服务器信息成功！\n";    echo "发送的内容为:<font color='red'>$in</font> <br>";}while($out = socket_read($socket, 8192)) {    echo "接收服务器回传信息成功！\n";    echo "接受的内容为:",$out;}echo "关闭SOCKET...\n";socket_close($socket);echo "关闭OK\n";?>
