CURL 同时测试一个 url 的多个 ip 地址：响应问题

Question

我正在对 URL 发出卷曲请求。此 URL 由许多服务器托管 ==>许多IP地址。 托管，

• 想象一下“www.example.com”由192.168.60.31
• 198.166.15.15
• 217.15.74.1

这是我所做的测试：

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);
    }

这里的问题是，当我可视化信息时，我得到这个：

如你所见：在某些服务器中我不要获取时间信息（一切都设置为 0） 这段代码有什么问题吗？

Answer 1

尝试将 CURLOPT_CONNECTTIMEOUT 设置为 0（无限期等待），看看是否有帮助。
