configure 2 small php sites that use same script

I am running 2 classified sites. Both use the same script. They are using the same database and the information is getting crossed. If I update one, it also updates the other with the wrong info. I need these 2 sites to each have a separate database so they run independently. Both sites need to be thoroughly tested to make sure banner rotation works properly and that ad submission works properly. I mainly need to be sure that if I update one site that it doesn't affect the other site. The one glitch left in the programs is when a user submits an ad, it only gives them the Featured option and not the non-featured option. This should be a quick, easy project for a coder. ## 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.
