Domain Registration & WHOIS lookups

This wouldn't be too hard. There are a couple of pear modules http://pear.php.net/package/Net_Whois which allows the lookup, and the other things could be done as well.

I followed up with this here:

Tried to post it here but got an error.

Well.. It's not really a patch issue.. but a viable solution..

Could use review..

WHOIS is not available for all domains. A durty dns lookup is. The following snippet could be used to check availability on the basis of existing DNS entry.

 if ($_GET['Submit']=="Check")
 {
  if (eregi("^[a-z0-9-]+(\.[a-z0-9-]+)*$",$_GET['domain']))
  {
   if (checkdnsrr ($_GET['domain'],"ANY"))
   {
     $errtxt="Already registered. Choose another.<br>";
   }
   else
   {
    $errtxt="Not registered</ br>";
   }
  }
  else
  {
   $errtxt="Invalid domain name</ br>";
  }
 }

if ($errtxt!='') echo $errtxt;

This is a backwards discussion. You shouldn't need to worry about whois queries because availability is usually accessible from the registrar API.

Look at integrating Tucows, Directi, enom, etc. and you'll have your availability checking.
