  $domain = preg_replace('/^http:\/\//i', '', $domain);
  $domain = preg_replace('/^www\./i', '', $domain);
  $domain = explode('/', $domain);
  $domain = trim($domain[0]);
  // split the TLD from domain name
  $_domain = explode('.', $domain);
  $lst = count($_domain)-1;
  $ext = $_domain[$lst];
  // You find resources and lists 
  // like these on wikipedia: 
  //

  if (!isset($servers[$ext])){
    die('Error: No matching nic server found!');
  }
  $nic_server = $servers[$ext];
  $output = '';
  // connect to whois server:
  if ($conn = fsockopen ($nic_server, 43)) {
    fputs($conn, $domain."\r\n");
    while(!feof($conn)) {
      $output .= fgets($conn,128);
    }
    fclose($conn);
  }
  else { die('Error: Could not connect to ' . $nic_server . '!'); }
  return $output;
}
// Some example queries:
print whois_query('jonasjohn.de');
print whois_query('example.com');
