linux-php using Curl to call the interface speed is very slow, the domain name for the IP speed is normal.

function Requestcurl ($url, $type = ' get ', $data =null)

{    $ch = curl_init();    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,false);     curl_setopt($ch, CURLOPT_HEADER, false);    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);    if('post'==$type){        curl_setopt($ch, CURLOPT_POST, true);        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);    }else if('delete'==$type){        curl_setopt ($ch, CURLOPT_CUSTOMREQUEST, "DELETE");           curl_setopt($ch, CURLOPT_POSTFIELDS,$data);    }else if('put'==$type){        curl_setopt ($ch, CURLOPT_CUSTOMREQUEST, "PUT");           curl_setopt($ch, CURLOPT_POSTFIELDS,$data);    }    curl_setopt($ch, CURLOPT_URL,$url);    $infos = curl_exec($ch);    curl_close($ch);    return $infos;}

The host ping is also available. The great God for guidance is appreciated

DNS domain name resolution problem only. In fact, I do not know very well. You'd better make a configuration to convert the corresponding domain name to IP
