Zipcode Proximity script

Find all the zip codes within a radius of x miles from another zip code OR find the distance between 2 zip codes. This program was written with simplicity in mind. It is VERY easy to use and install. I even included a working example. This script can be used alone or easily integrated with more complex projects such as a store locater. I have also included a zip code database MySQL install query. All you do is copy and paste the query in phpMYadmin and it will install the zip code database with 42,620 records. If you need a custom feature, email me and I will write it for you. Best of all its only $3!
