modifying this php whois lookup script

hi,

i have the following whois lookup script, that can check check the availablity of a domain by calling the script like this: index.php?domain=domain&ext=com&option=check and basically if the domain is available it displays a link to order it if not it displays a link to check the whois details on it.

The only problem with the script is that when it is run like index.php?domain=s&ext=com&option=check the extension is specified as a param, can someone help me to convert this code so that i can somehow search for more than one extension at the same time e.g.

index.php?domain=s&ext=com&ext=net&ext=org&option=check

any help would be appreciated.

cheers
