Find the nearest store to a customer

Maps API: http://code.google.com/apis/maps/index.html


If you only need to search your own store locations, I would save the coordinates of each store in your database and execute a query ordered by distance ((customer latitude - store latitude) + (customer longitude - store longitude)).
See if you can use the Maps API to get the customer's coordinates.
The bonus of using the Google tools is that they will accept any sensible sort of input: suburb names and street addresses as well as postcodes.
