I am kind of new to this and i am looking for ideas, I am trying to build a web application that allows a user to input
his/her address and based on that address it returns all available branches within 10 miles, now i have this branches (Addresses and Zip code) in the Database
but how do i calculate if the branches are within 10 miles of the address

Are you asking about spherical trignometry, or are you asking how to find the location of a zip code?
