不知道可不可以再发,好像会在这期杂志上出现,这是大部分内容
客户端与服务端的代码分别如下:
Server.php
<?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($sock) . " ";
}
if (($ret = socket_bind($sock, $address, $port)) < 0) {
echo "创建套接字失败原因 " . socket_strerror($ret) . " ";
}
//监听
if (($ret = socket_listen($sock, 5)) < 0) {
echo "监听失败原因 " . socket_strerror($ret) . " ";
}
do {
//接收命令
if (($msgsock = @socket_accept($sock)) < 0) {
echo "命令接收失败原因: " . socket_strerror($msgsock) . " ";
break;
}
$msg = " PHP Test Server. " .
"用quit,shutdown,sun...等命令测试. ";
@socket_write($msgsock, $msg, strlen($msg));
do {
if (false === ($buf = @socket_read($msgsock, 2048, PHP_NORMAL_READ))) {
echo "socket_read() failed: reason: " . socket_strerror($ret) . " ";
break 2;
}
if (!$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'. ";
socket_write($msgsock, $talkback, strlen($talkback));
echo "$buf ";
} while (true);
socket_close($msgsock);
} while (true);
socket_close($sock);
?>
Client.php
<?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) . " ";
} else {
echo "OK，HE HE. ";
}
$result = socket_connect($socket, $address, $service_port);
if ($result < 0) {
echo "SOCKET连接失败原因: ($result) " . socket_strerror($result) . " ";
} else {
echo "OK. ";
}
//发送命令
$in = "HEAD / HTTP/1.1 ";
$in .= "Connection: Close ";
$out = '';*/
echo "Send Command..........";
$in = "sun ";
socket_write($socket, $in, strlen($in));
echo "OK. ";
echo "Reading Backinformatin: ";
while ($out = socket_read($socket, 2048)) {
echo $out;
}
echo "Close socket........";
socket_close($socket);
echo "OK,He He. ";
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....
如果你看懂了,现在你可以关闭你的阿帕奇了,打开端口为80,用这程序实现打开一个网站的首页..留给还不会的人思考..
