zip code radius search

[Guest]

PHP/MySQL

I want to build a search query that has several filters, including a search by zip code with a drop selected radius of miles from that zip code... similar to many jobs sites and other store location types models.

Any suggestions?

Not tried this, but used some of the databases for other things.

http://www.ip2location.com/ip-country-region-city-latitude-longitude-zipcode.aspx

above will get you the users zip code along with latitude-longitude

below is for asp users to calculate the distance between latitude and the
longtitude. they have this avail for other code formates too.

using php.

i've found some databases with zips, and some codes... but right now i'm contemplating on whether it's even worth doing... a lot involved.

anyone had a great way of doing this that's really simple?
