php采用curl实现伪造IP来源的方法，curlip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复制代码代码如下:$binfo =array('Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; InfoPath.2; AskTbPTV/5.17.0.25589; Alexa Toolbar)','Mozilla/5.0 (Windows NT 5.1; rv:22.0) Gecko/20100101 Firefox/22.0','Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET4.0C; Alexa Toolbar)','Mozilla/4.0(compatible; MSIE 6.0; Windows NT 5.1; SV1)',$_SERVER['HTTP_USER_AGENT']);//123.125.68.*//125.90.88.*定义伪造IP来源段，这里我找的是百度的IP地址复制代码代码如下:$cip = '123.125.68.'.mt_rand(0,254);$xip = '125.90.88.'.mt_rand(0,254);$header = array('CLIENT-IP:'.$cip,'X-FORWARDED-FOR:'.$xip,);利用curl开始向服务器发送伪造信息复制代码代码如下: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;}获取到数据我们再保存复制代码代码如下:function saveimgs( $handle ){$fp = fopen('a.jpg',"w");fwrite($fp,$handle);unset($fp);unset($handle);}测试伪造IP实例复制代码代码如下:$url ='http://www.bkjia.com/images/logo.gif';$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192.168.1.108 - - [22/Jul/2013:10:29:37 +0800] "GET /test.php HTTP/1.1" 200 1241244 "-" "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 1241244 "-" "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。
