这篇文章主要介绍了PHP curl伪造IP地址和header信息代码实例,本文给出服务器端和客户端实现代码,提供伪造功能和服务器端检测代码,需要的朋友可以参考下

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

代码如下:

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

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

$headerArr = array();

foreach( $headers as $n => $v ) {

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

}

ob_start();

$ch = curl_init();

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

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

curl_setopt ($ch, CURLOPT_REFERER, "/ "); //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

代码如下:

function GetIP(){

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

$cip = $_SERVER["HTTP_CLIENT_IP"];

else if(!emptyempty($_SERVER["HTTP_X_FORWARDED_FOR"]))

$cip = $_SERVER["HTTP_X_FORWARDED_FOR"];

else if(!emptyempty($_SERVER["REMOTE_ADDR"]))

$cip = $_SERVER["REMOTE_ADDR"];

else

$cip = "无法获取!";

return $cip;

}

echo "
访问IP: ".GetIP()."
";

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