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

复制代码 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, "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

复制代码 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"];
