Ok I am starting to understand what about calling it? You gave me all of these modules and what I am really trying to do is give a tool kit ot myself and my people so that when I need to edit the way sessions are stored and users are handled it does not break as this eventually is going to have alot of people working on it.
At the beginning of my script I open a connection to the database and just use it. I have done that it works well. Now I want to provide a set of functions for my self and my people to access that database but not from cutting and pasting the files into each script as they are written.
I guess I need more of a module then? And have when needed thm call in the function as in user::validate_username ?
