摘要：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( $headers as $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

[u]复制代码[/u] 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 "<br>访问IP: ".GetIP()."<br>";

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