Convert ASP to PHP Zip Code Radius calculator

I need a simple tool to use with the 'standard' database from www.zip-codes.com. I have a tool that they have provided that is in ASP but I am going to load this database into a MySQL database and run the utility in PHP. The object/function will need two variables: Zip Code and distance in miles. The object/function needs to return all zip codes within that radius using the database. The database has zip codes, Lat & Long info and more if you need. I am including an example of the code that [login to view URL] has provided in ASP. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
