Hey so I am trying to develop a search for my website which would search by radius from zip code, or city, how would I do that, any tutorials, do you build a database for this, or how would it work?
Php and MySQL are the tools of choice
Selecting points within a bounding circle http://www.movable-type.co.uk/scripts/latlong-db.html
The Zip Code Database Project http://sourceforge.net/projects/zips/
anyone got any experience at this that might be able to help?
