Script for searching database

Hello!

I am currently in the process of setting up a website that allows English users to add, manage and view events in their area. This would also accommodate features unique to YouTube and MySPACE along with a revolutionary Member System.
One problem we have encountered is how users would search our events database.

What I would like to have, is users input their Postal code or town into a a search box, and then it would search a database or area of the site, and spit out page with information about all the events in the area. Much like on Fast Food rester aunts and Super markets having their "Enter Postcode to find your nearest outlet!".

Is there a script or code out there that does what I have explained above?
If so, could you provide me with a link or post it in this thread.

Many Thanks.

Regards,
