megashell Posted March 1, 2006 Share Posted March 1, 2006 Many websites I have something like a store locator where you enter a zipcode and it gives nearby stores up to 20 or 30 miles from your zip code. How would I go about making something like this?Thanks! Link to comment https://forums.phpfreaks.com/topic/3867-zip-code-locator/ Share on other sites More sharing options...
zq29 Posted March 1, 2006 Share Posted March 1, 2006 First of all you'll need a database of all of your zip codes and their latitude and longitudes. Then there is a massive and complicated mathematical function to work out the distance of which I currently don't have close to me, but a search on Google should find it for you.
