CURL同時測試一個url的很多ip地址：響應問題

Question

正在對URL進行curl請求。這個URL由許多服務器託管==>許多IP地址。 想象 「www.example.com」 由

• 192.168.60.31
• 198.166.15.15
• 217.15.74.1

這裏舉辦的是，我做了測試：

public function curlInfosMulti($ips,$url, $timeout, $method, $params) { 



     $count= count($ips); 
     $container = array(); 
     $tab = array('Host:'.$url); 
// set URL and other appropriate options 
     for ($i=0; $i<$count; $i++) 
     { 
      $container[$i] = curl_init(); 
      curl_setopt($container[$i], CURLOPT_URL, $ips[$i]); 
      curl_setopt($container[$i], CURLOPT_HTTPHEADER, $tab); 
      curl_setopt($container[$i], CURLOPT_HEADER, 1); 
      curl_setopt($container[$i], CURLOPT_RETURNTRANSFER, true); 
     } 


//create the multiple cURL handle 
     $mh = curl_multi_init(); 



     for ($i=0; $i<$count; $i++) 
     { 
      curl_multi_add_handle($mh, $container[$i]); 
     } 









     $running = null; 
//execute the handles 
     do { 
      curl_multi_exec($mh, $running); 
     } while ($running > 0); 

     $response_1 = curl_multi_getcontent($container[1]); 
     //$response_2 = curl_multi_getcontent($ch2); 
     $infos0 = curl_getinfo($container[0]); 
     $infos1 = curl_getinfo($container[1]); 
     $infos2 = curl_getinfo($container[2]); 
     $infos3 = curl_getinfo($container[3]); 
     $infos4 = curl_getinfo($container[4]); 
     $infos5 = curl_getinfo($container[5]); 

     print_r($infos0); 
       echo '</br></br></br>'; 
     print_r($infos1); 
       echo '</br></br></br>'; 
     print_r($infos2); 
     echo '</br></br></br>'; 
     print_r($infos3); 
     echo '</br></br></br>'; 
     print_r($infos4); 
     echo '</br></br></br>'; 
     print_r($infos5); 

//close the handles 

      for ($i=0; $i<$count; $i++) 
     { 

     curl_multi_remove_handle($mh, $container[$i]); 
     } 
     curl_multi_close($mh); 
    } 

這裏的問題是，當我想象的信息我得到這個：

正如你看到的：在某些服務器上我沒有得到時間信息（一切都被設置爲0） 是有這個代碼的任何問題嗎？

Answer 1

嘗試將CURLOPT_CONNECTTIMEOUT設置爲0（等待無限期）並查看是否有幫助。
