基于php socket(fsockopen)的应用实例分析

导读：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：server.php div class="codetitle" a style="CURSOR: pointer" data="49978" class="c

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：server.php

<div class="codetitle"><a style="CURSOR: pointer" data="49978" class="copybut" id="copybut49978" onclick="doCopy('code49978')"> 代码如下:<div class="codebody" id="code49978">
<?php
error_reporting(E_ALL);
set_time_limit(0);
$address = '127.0.0.1';
$port = 10008;
//创建端口
if (($sock = socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) === false) {
echo "socket_create() failed:reason:" . socket_strerror(socket_last_error()) . "n";
}
//绑定
if (socket_bind($sock,$address,$port) === false) {
echo "socket_bind() failed :reason:" . socket_strerror(socket_last_error($sock)) . "n";
}
//监听
if (socket_listen($sock,5) === false) {
echo "socket_bind() failed :reason:" . socket_strerror(socket_last_error($sock)) . "n";
}
while (true) {
//得到一个链接
if (($msgsock = socket_accept($sock)) === false) {
echo "socket_accepty() failed :reason:".socket_strerror(socket_last_error($sock)) . "n";
break;
}
//welcome 发送到客户端
$msg = "1.server send:welcome
";
socket_write($msgsock,$msg,strlen($msg)); //返回信息给客户端
echo 'read client messagen';
$buf = socket_read($msgsock,8192); //获取客户端发送过来的信息
$talkback = "2.received message:$bufn";
echo $talkback;
if (false === socket_write($msgsock,$talkback,strlen($talkback))) { //返回信息给客户端
echo "socket_write() failed reason:" . socket_strerror(socket_last_error($sock)) ."n";
} else {
echo 'send success';
}
socket_close($msgsock);
}
socket_close($sock);

客户端代码：fsocket.php
<div class="codetitle"><a style="CURSOR: pointer" data="41692" class="copybut" id="copybut41692" onclick="doCopy('code41692')"> 代码如下:<div class="codebody" id="code41692">
<?php
$fp = fsockopen("127.0.0.1",10008,&$errno,&$errstr,10);
if (!$fp) {
echo $errstr . " (". $errno . ")
n";
} else {
$in = "HEAD / http/1.1rn";
$in .= "HOST: localhost rn";
$in .= "Connection: closernrn";
fputs($fp,$in);
while (!feof($fp)) {
echo fgets($fp,128);
}
fclose($fp);
}
