查了下，CURL确实很强悍的可以伪造IP和来源。

1.php 请求 2.php 。
1.php代码：
<?php $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "http://localhost/2.php"); curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:8.8.8.8', 'CLIENT-IP:8.8.8.8'));  //构造IP curl_setopt($ch, CURLOPT_REFERER, "http://www.gosoa.com.cn/ ");   //构造来路 curl_setopt($ch, CURLOPT_HEADER, 1); $out = curl_exec($ch); curl_close($ch);
2.php代码如下：
<?php function getClientIp() {     if (!empty($_SERVER["HTTP_CLIENT_IP"]))         $ip = $_SERVER["HTTP_CLIENT_IP"];     else if (!empty($_SERVER["HTTP_X_FORWARDED_FOR"]))         $ip = $_SERVER["HTTP_X_FORWARDED_FOR"];     else if (!empty($_SERVER["REMOTE_ADDR"]))         $ip = $_SERVER["REMOTE_ADDR"];     else         $ip = "err";     return $ip; } echo "IP: " . getClientIp() . ""; echo "referer: " . $_SERVER["HTTP_REFERER"]; echo "IP: " . getClientIp() . ""; echo "referer: " . $_SERVER["HTTP_REFERER"];
伪造成功，这是不是给“刷票”的朋友提供了很好的换IP的方案！！
哈哈。

结果：
HTTP/1.1 200 OK Date: Wed, 03 Apr 2013 06:20:42 GMT Server: Apache/2.2.22 (Win32) PHP/5.3.13 X-Powered-By: PHP/5.3.13 Content-Length: 44 Content-Type: text/html
IP: 8.8.8.8
