我是靠谱客的博主飞快鱼，最近开发中收集的这篇文章主要介绍PHP curl伪造IP地址和header信息代码实例，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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"];
