Add column to PHP Script

I have the following PHP script on my server: [login to view URL] I want you to add an additional two columns: ".com" and ".[login to view URL]". Each column should do a "whois" on the keyword (without spaces/punctuation), and state whether it's "taken" or "not taken". For example, if the keyword is "cheap holidays", then both columns would say "taken" - because "[login to view URL]" and "[login to view URL]" are taken. It should do a domain lookup for each keyword returned, so you might want to use a bulk lookup like this one: [login to view URL] Thanks
