基于php socket(fsockopen)的应用实例分析

fsockopen函数能够运用，首先要开启php.ini中的allow_url_open=on;

fsockopen是对socket客户端代码的封装，该函数中封装了socket_create,socket_connect。


服务器端代码：rver.php

复制代码 代码如下:

<?php

error_reporting(e_all);

t_time_limit(0);

$address = ‘127.0.0.1’;

$por生死搭档t = 10008;

//创建端口

if (($sock = socket_create(af_inet, sock_stream, sol_tcp)) === fal) {

echo “socket_create() failed:reason:” . socket_strerror(socket_last_error()) . “\n”;

}

//绑定

if (socket_bind($sock, $address, $port) === fal) {

echo “socket_bind() failed :reason:” . socket_strerror(socket_last_error($sock)) . “\n”;

}

//监听

if (socket_listen($sock, 5) === fal) {

echo “socket_长春财经学院学费bind() failed :reason:” . socket_strerror(socket_last_error($sock)) . “\n”;

}

while (true) {

//得到一个链接

if (($msgsock = socket_accept($sock)) === fal) {

echo “socket_accepty() failed :reason:”.socket_strerror(socket_last_error($sock)) .求成 “\n̶节目单制作1;;

break;

}

//welcome 发送到客户端

$msg = “1.<font color=’red’>rver nd:welcome</font><br/>”;

socket_write($msgsock, $msg, strlen($msg)); //返回信息给客户端

echo ‘read client message\n’;

$buf = socket_read($msgsock, 8192); //获取客户端发送过来的信息

$talkback = “2.received message:$buf\n”;

echo $talkback;

if (fal === socket_write($清明是几月几日msgsock, $talkback, strlen($talkback))) { //返回信息给客户端

echo “socket_write() failed reason:” . socket_strerror(socket_last_error($sock)) .”\n”;

} el {

echo ‘nd success’;

}

socket_clo($msgsock);

}

socket_clo($sock);

客户端代码：fsocket.php


复制代码 代码如下:

<?php

$fp = fsockopen(“127.0.0.1”, 10008, &$errno, &$errstr, 10);

if (!$fp) {

echo $errstr . ” (“. $errno . “)<br>n”;

} el {

$in = “head / http/1.1\r\n”;

$in .= “host: localhost \r\n”;

$in .= “connection: clo\r\n\r\n”;

fputs($fp, $in);

while (!feof($fp)) {

echo fgets($fp, 128);

}

fclo($fp);

}
