Question for Java/PHP Programmers
Does anyone know how I can incorporate, using SQL, Java, and PHP, a function that, when 2 zip codes are entered, it gives an approximate distance between the 2 zip codes. Like, somewhere within 20 miles or so?
I know UPS does it to give estimates on shipping costs. Also places like mapquest use it to give directions. I dont' need something that complex, just an approximation between 2 area codes.
