异步执行的代码：

<?php
   ignore_user_abort(1); //由于异步请求后会立即断开连接，默认会终止脚本，忽略掉
   set_time_limit(0); //取消脚本执行延时上限
   for ($i = 1; $i < 10; $i++)
   {
      $ch = curl_init(); 
      curl_setopt($ch, CURLOPT_URL, "https://www.haiyun.me/?$i");
      curl_setopt($ch, CURLOPT_REFERER, "http://www.test.com");
      curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:24.0) Gecko/20100101 Firefox/24.0");
      curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,3);
      curl_setopt($ch,CURLOPT_TIMEOUT,3);
      curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
      curl_exec($ch);
   }
