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
$binfo=array('Mozilla/4.0(compatible;MSIE8.0;WindowsNT5.1;Trident/4.0;.NETCLR2.0.50727;InfoPath.2;AskTbPTV/5.17.0.25589;AlexaToolbar)','Mozilla/5.0(WindowsNT5.1;rv:22.0)Gecko/20100101Firefox/22.0','Mozilla/4.0(compatible;MSIE8.0;WindowsNT5.1;Trident/4.0;.NET4.0C;AlexaToolbar)','Mozilla/4.0(compatible;MSIE6.0;WindowsNT5.1;SV1)',$_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:'.$xip, );
利用curl开始向服务器发送伪造信息
functiongetimgs($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
functionsaveimgs($handle)
{
$fp=fopen('a.jpg',"w");
fwrite($fp,$handle);
unset($fp);
unset($handle);
}测试伪造IP实例
$url='https://www.nhooo.com/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

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。
