我正在对 URL 发出 curl 请求。此 URL 由许多服务器托管 ==> 许多 IP 地址。想象一下“www.example.com”由
- 192.168.60.31
- 198.166.15.15
- 217.15.74.1
这是我做的测试：
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，当我将信息可视化时，我得到了这个：

如您所见：在某些服务器中，我不获取时间信息（一切都设置为 0）此代码有什么问题吗？
