thanks for the reply man, but I need something more detailed hehe
I am looking at this site http://www.php-shopping-cart-tutorial.com/introduction.htm and I've downloaded the source-code. I am looking at it right now and I have no idea where to start. it's like A->B, A->C, C->E, E->B, B->D, ...
I know how the whole thing works I can code it in just maybe 5 php files? more or less... but I want to start learning how to code this way having modules/templates/db separated in folders because it will be a lot easier maintaining the site.
