PHP programming forum. Ask questions or help people concerning PHP code. Don't understand a function? Need help implementing a class? Don't understand a class? Here is where to ask. Remember to do your homework!
Don' t understand what you want:
-to customize the product then use Flash (search for tutorial)
-to have a "nicer" URL then search here for URL rewriting or mod_rewrite
-using PHP with Flash then buy a book for this matter or search for a tutorial using Google or Yahoo Search
Also, you may want to look into Adobe Flex. Its an API built on top of flash and its really really damn nice for doing this kind of stuff. Its well documented and adobe has a flex IDE in eclipse. There are a lot of tutorials on the adobe site as well as examples for integrating i with a php server.
