I was hoping someone could advise me. Iíve got a background in PHP and so was thinking of developing a website that lists domains that are either within days of their expiry or just expired.

However the more I research it the more it seems to be not quite as simple as I first thought. To come to the point it seems that getting the expiry date with PHP would mean interfacing with an API of say Namejet, Snapnames or constantly reading from a .csv file these companies provide. You canít just get it from querying a whois server?

Could someone confirm this and if possible provide any other info from the technical side of things regarding what actually happens when a domain doesnít get renewed.

Many thanks
