There is a class called zipLocator. I think I found it at
phpclasses.org. It uses a large zipcode database, which can be
downloaded for free (the address is in the class).
This will return all zipcodes within a specified distance from the
target zipcode (10 mi, 50 mi, etc.).
If you can't find it, contact me offline.
