本文實例講述了php采用curl實現偽造IP來源的方法。可以實現偽造IP來源, 偽造域名, 偽造用戶信息，分享給大家供大家參考。具體實現方法如下：
定義偽造用戶浏覽器信息HTTP_USER_AGENT
復制代碼 代碼如下:$binfo =array('Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; InfoPath.2; AskTbPTV/5.17.0.25589; Alexa Toolbar)','Mozilla/5.0 (Windows NT 5.1; rv:22.0) Gecko/20100101 Firefox/22.0','Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET4.0C; Alexa Toolbar)','Mozilla/4.0(compatible; MSIE 6.0; Windows NT 5.1; SV1)',$_SERVER['HTTP_USER_AGENT']);
//123.125.68.*
//125.90.88.*
定義偽造IP來源段，這裡我找的是百度的IP地址
復制代碼 代碼如下:$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開始向服務器發送偽造信息
復制代碼 代碼如下: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;
}
獲取到數據我們再保存
復制代碼 代碼如下:function saveimgs( $handle )
{
$fp = fopen('a.jpg',"w");
fwrite($fp,$handle);
unset($fp);
unset($handle);
}
測試偽造IP實例
復制代碼 代碼如下:$url ='http://www.jb51.net/images/logo.gif';
$u = $binfo[mt_rand(0,3)];
saveimgs(getimgs($url,$u,$header));
這樣就在你當前目錄保存成功了一個文件a.jpg文件，我現可以查看服務器日志是不是我們自定的用戶信息呢

看出來了吧，完全正確啊，只是IP地址我怎麼沒測試出來，這個使用php獲取ip地址時就會顯示我偽造IP地址了。
希望本文所述對大家的PHP程序設計有所幫助。
