I would like to put on my website the ability for my users to enter their zip code and then compare it to the zip codes of all of our locations and determine which one is the closest. I am new to Web Development, and I'm not sure on where to start. I have the stores with zip codes saved in a mysql database.
Thanks for all of your help.
