PHP curl伪造IP地址和header信息代码实例

curl虽然功能强大，但是只能伪造$_SERVER["HTTP_X_FORWARDED_FOR"]，对于大多数IP地址检测程序来说，$_SERVER["REMOTE_ADDR"]很难被伪造：

首先是client.php的代码


$headers['CLIENT-IP']='202.103.229.40'; 

$headers['X-FORWARDED-FOR']='202.103.229.40';

 

$headerArr=array(); 

foreach($headersas$n=>$v){ 

   $headerArr[]=$n.':'.$v;  

}

 

ob_start();

$ch=curl_init();

curl_setopt($ch,CURLOPT_URL,"http://localhost/curl/server.php");

curl_setopt($ch,CURLOPT_HTTPHEADER,$headerArr); //构造IP

curl_setopt($ch,CURLOPT_REFERER,"http://www.163.com/");  //构造来路

curl_setopt($ch,CURLOPT_HEADER,1);

 

curl_exec($ch);

curl_close($ch);

$out=ob_get_contents();

ob_clean();

 

echo$out;

然后是server.php


functionGetIP(){

   if(!emptyempty($_SERVER["HTTP_CLIENT_IP"]))

       $cip=$_SERVER["HTTP_CLIENT_IP"];

   elseif(!emptyempty($_SERVER["HTTP_X_FORWARDED_FOR"]))

       $cip=$_SERVER["HTTP_X_FORWARDED_FOR"];

   elseif(!emptyempty($_SERVER["REMOTE_ADDR"]))

       $cip=$_SERVER["REMOTE_ADDR"];

   else

   $cip="无法获取！";

   return$cip;

}

echo"<br>访问IP:".GetIP()."<br>";

echo"<br>访问来路:".$_SERVER["HTTP_REFERER"];
