php采用curl实现伪造IP来源的方法

本文实例讲述了php采用curl实现伪造ip来源的方法。可以实现伪造ip来源, 伪造域名, 伪造用户信息，分享给大家供大家参考。具体实现方法如下：

定义伪造用户浏览器信息http_user_agent

$binfo =array('mozilla/4.0 (compatible; msie 8.0; windows nt 5.1; trident/4.0; .net clr 2.0.50727; infopath.2; asktbptv/5.17.0.25589; alexa toolbar)','mozilla/5.0 (windows nt 5.1; rv:22.0) gecko/20100101 firefox/22.0','mozilla/4.0 (compatible; msie 8.0; windows nt 5.1; trident/4.0; .net4.0c; alexa toolbar)','mozilla/4.0(compatible; msie 6.0; windows nt 5.1; sv1)',$_server['http_user_agent']);
//123.125.68.*
//125.90.88.*

定义伪造ip来源段，这里我找的是百度的ip地址

$cip = '123.125.68.'.mt_rand(0,254);
$xip = '125.90.88.'.mt_rand(0,254);
$header = array(
'client-ip:'.$cip,
'x-forwarded-for:'.$xip,
);

利用curl开始向服务器发送伪造信息

function getimgs( $url,$userinfo,$header)
{
 $ch = curl_init();
 $timeout = 5;
 curl_setopt ($ch, curlopt_url, "$url");
 curl_setopt ($ch, curlopt_httpheader, $header);
 curl_setopt ($ch, curlopt_referer, "http://www.baidu.com/");
 curl_setopt ($ch, curlopt_returntransfer, 1);
 curl_setopt ($ch, curlopt_useragent, "$userinfo");
 curl_setopt ($ch, curlopt_connecttimeout, $timeout); 
 $contents = curl_exec($ch);
 curl_close($ch);
 return $contents;
}

获取到数据我们再保存

function saveimgs( $handle )
{
 $fp = fopen('a.jpg',"w");
 fwrite($fp,$handle);
 unset($fp);
 unset($handle);
}

测试伪造ip实例

$url ='//www.jb51.net/images/logo.gif';
$u = $binfo[mt_rand(0,3)];
saveimgs(getimgs($url,$u,$header));

这样就在你当前目录保存成功了一个文件a.jpg文件，我现可以查看服务器日志是不是我们自定的用户信息呢

192.168.1.108 - - [22/jul/2013:10:29:37 +0800] "get /test.php http/1.1" 200 1244 "-" "mozilla/4.0 (compatible; msie 8.0; windows nt 5.1; trident/4.0; .net clr 2.0.50727; infopath.2; asktbptv/5.17.0.25589; alexa toolbar)"
192.168.1.108 - - [22/jul/2013:10:29:37 +0800] "get / http/1.1" 200 40538 "http://www.baidu.com/" "mozilla/4.0 (compatible; msie 8.0; windows nt 5.1; trident/4.0; .net4.0c; alexa toolbar)"
192.168.1.108 - - [22/jul/2013:10:29:37 +0800] "get /test.php http/1.1" 200 1244 "-" "mozilla/4.0 (compatible; msie 8.0; windows nt 5.1; trident/4.0; .net clr 2.0.50727; infopath.2; asktbptv/5.17.0.25589; alexa toolbar)"
192.168.1.108 - - [22/jul/2013:10:29:37 +0800] "get / http/1.1" 200 40538 "http://www.baidu.com/" "mozilla/5.0 (windows nt 5.1; rv:22.0) gecko/20100101 firefox/22.0"

看出来了吧，完全正确啊，只是ip地址我怎么没测试出来，这个使用php获取ip地址时就会显示我伪造ip地址了。

希望本文所述对大家的php程序设计有所帮助。
