Whois server not returning results?

Hi I have been messing with this Whois script I got of the 'net, and have been messing with variables and arrays for ever trying to figure out why it won't return the whois results for Google and Facebook (i tested google, as this is the obvious one), then tested facebook after learning it is to do with Whois spamming, and people adding google.com subdomains which this script picks up on (the same happens with facebook)...

After doing my homework i managed to get it to return a list of all results (by removing the section of the script that adds the required "=".$domain to the domain variable.

After that, all results were returned, and i learned the script was picking up the Whois server of the first result (which is a google.com.with.added.spam.com) and therefore "google.com" could not be found on the same whois server as "google.com.with.added.spam.com" therefore it is returning blank.

As to fix it I have tried everything from reversing the preg_match_all array (to grab the last whois server) to editing all the variables i can think of..

Any help would be greatly appreciated.

Thanks in advance!!!

And now the code:

$domain = $_GET['domain'];

When you are trying to send the domain(For example:google.com) to your script from the form, instead of sending it as 'google.com' add the word 'domain' i.e(domain google.com).

What this does, it tells the whois server to find this domain(i.e google.com) and not any other domain that has the word google in it.

So in the function "LookupDomain($domain)" be sure that the value of $domain should be 'domain google.com' for it to display the proper result.

change the .com server to "whois.crsnic.net" and it should work

This script not working yet. so you can try the following code

<?php function whois_query($domain)
{

 // fix the domain name:
 $domain = strtolower(trim($domain));
 $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];

 // the list of whois servers
 // most taken from www.iana.org/domains/root/db/
