php使用curl伪造来源ip和refer的方法示例

//随机ip
function rand_ip(){
 $ip2id= round(rand(600000, 2550000) / 10000); //第一种方法，直接生成
 $ip3id= round(rand(600000, 2550000) / 10000);
 $ip4id= round(rand(600000, 2550000) / 10000);
 //下面是第二种方法，在以下数据中随机抽取
 $arr_1 = array("218","218","66","66","218","218","60","60","202","204","66","66","66","59","61","60","222","221","66","59","60","60","66","218","218","62","63","64","66","66","122","211");
 $randarr= mt_rand(0,count($arr_1)-1);
 $ip1id = $arr_1[$randarr];
 return $ip1id.".".$ip2id.".".$ip3id.".".$ip4id;
}
//抓取页面内容
function curl($url){
  $ch2 = curl_init();
  $user_agent = "mozilla/5.0 (windows nt 6.1; wow64) applewebkit/537.36 (khtml, like gecko) chrome/29.0.1547.66 safari/537.36";//模拟windows用户正常访问
  curl_setopt($ch2, curlopt_url, $url);
  curl_setopt($ch2, curlopt_timeout, 10);
  curl_setopt($ch2, curlopt_httpheader, array('x-forwarded-for:'.rand_ip(), 'client-ip:'.rand_ip()));
//追踪返回302状态码，继续抓取
  curl_setopt($ch2, curlopt_header, true); 
  curl_setopt($ch2, curlopt_returntransfer, true); 
  curl_setopt($ch2, curlopt_followlocation, true);
  curl_setopt($ch2, curlopt_nobody, false);
  curl_setopt($ch2, curlopt_referer, 'http://www.baidu.com/');//模拟来路
  curl_setopt($ch2, curlopt_useragent, $user_agent);
  $temp = curl_exec($ch2);
  curl_close($ch2);
  return $temp;
}
