Being a newbie to php is something you are going to want to solve before diving into projects. I can tell you this from first hand experience, if you do not understand the code you are working with, you are going to wind up with a whole lot of silly mistakes that would never had occurred had you understood what you were doing in the first place.
Lectures aside.. some code showing what you have already started working on would be helpful.
A little clarification goes a long way.
