一、server.PHP服务端

<?php  
error_reporting(E_ALL);  
set_time_limit(0);  
ob_implicit_flush();  
//本地IP  
$address = 'localhost';  
//设置用111端口进行通信  
$port = 111;  
//创建SOCKET  
if (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) < 0) {  
        echo "socket创建失败原因 " . socket_strerror($sock) . "\n";  
}  
  
if (($ret = socket_bind($sock, $address, $port)) < 0) {  
        echo "创建套接字失败原因 " . socket_strerror($ret) . "\n";  
}  
//监听  
if (($ret = socket_listen($sock, 5)) < 0) {  
        echo "监听失败原因 " . socket_strerror($ret) . "\n";  
}  
do {  
    //接收命令   
    if (($msgsock = @socket_accept($sock)) < 0) {  
        echo "命令接收失败原因: " . socket_strerror($msgsock) . "\n";  
        break;  
    }  
    $msg = "\nPHP Test Server. \n" ."用quit,shutdown,sun...等命令测试.\n";  
  
    @socket_write($msgsock, $msg, strlen($msg));  
  
    do {  
        if (false === ($buf = @socket_read($msgsock, 2048, PHP_NORMAL_READ))) {  
                echo "socket_read() failed: reason: " . socket_strerror($ret) . "\n";  
                break 2;  
        }  
        if (!$buf = trim($buf)) {  
                continue;  
        }  
        if ($buf == 'quit') {  
                break;  
        }  
        if ($buf == 'shutdown') {  
                socket_close($msgsock);  
                break 2;  
        }  
        if ($buf == 'sun') {  
                echo'what are you doing?';  
        }  
        $talkback = "Backinformation : '$buf'.\n";  
        socket_write($msgsock, $talkback, strlen($talkback));  
        echo "$buf\n";  
    } while (true);  
  
    socket_close($msgsock);  
  
} while (true);  
  
socket_close($sock);  
?>  

 

二、client.php客户端:

<?php  
error_reporting(E_ALL);  
//端口111  
$service_port = 111;  
//本地  
$address = 'localhost';  
//创建 TCP/IP socket  
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);  
if ($socket < 0) {  
        echo "socket创建失败原因: " . socket_strerror($socket) . "\n";  
} else {  
        echo "OK，HE HE.\n";  
}  
$result = socket_connect($socket, $address, $service_port);  
if ($result < 0) {  
        echo "SOCKET连接失败原因: ($result) " . socket_strerror($result) . "\n";  
} else {  
        echo "OK.\n";  
}  
//发送命令  
$in = "HEAD / HTTP/1.1\r\n";  
$in .= "Connection: Close\r\n\r\n";  
$out = '';  
echo "Send Command..........";  
$in = "sun\n";  
socket_write($socket, $in, strlen($in));  
echo "OK.\n";  
echo "Reading Backinformatin:\n\n";  
while ($out = socket_read($socket, 2048)) {  
        echo $out;  
}  
echo "Close socket........";  
socket_close($socket);  
echo "OK,He He.\n\n";  
?>

这两段代码是简单介绍用PHP实现客户端和服务端的通信
client.php
server.php
具体操作,在DOS下用PHP命令打开SERVER,处于监听状态..
再打开一个DOS窗口,用PHP命令打开CLIENT,会得到服务端的回应....
