I have this PHP script to fetch whois information of domain. It works, but when I try to connect whois server via proxy, then it doesnt work. The proxy ip is taken from proxylist.hidemyass.com. What I do wrong? Thank you for help.
$server = "whois.nic.cz";
$domain = "klikzone.cz";
function QueryWhoisServer($server, $domain){
$proxy = "85.111.25.189:8080";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $server);
curl_setopt($ch, CURLOPT_PORT, 43);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $domain . "\r\n");
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
