curl伪造referer与来源IP

[one.php]

<?php

curl_setopt ($ch, CURLOPT_URL, 'http://localhost/curl/two.PHP');

//伪造来源referer
curl_setopt ($ch,CURLOPT_REFERER,$referer);

//伪造来源ip
curl_setopt($ch, CURLOPT_HTTPHEADER, $header_ip);

//提交post传参
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);

//加上这个表示执行curl_exec是把输出做为返回值,不会输出到浏览器

echo $out_put;

[two.php]

 //[注]此处的IP打印顺序是目前很多开源系统的IP获取顺序

 echo $_SERVER['HTTP_CLIENT_IP'];
 echo '<br>';
 echo $_SERVER['HTTP_X_FORWARDED_FOR'];
 echo '<br>';
 echo $_SERVER['REMOTE_ADDR'];

 //POST数据
 echo '<hr>[POST]<br><pre>';
 var_dump($_POST);
