Need help getting started with php

HI. I’m starting a new design using php and html instead of flash and I have 0% knowledge of php. The only reason I want to use php in this version is to save bandwidth. In power-fusion.com , the have one layout and then a seperate page load in the center so the nav menus and such dont need to be re-loaded. Can someone help walk me through this. I have dreamweave if that helps.

Thanks.

P.S. Whoever helps will have their site advertised for free. and be givin credit for it.
