help in coding

[fazeera]

I need help in the following:
1. The dynamic PHP pages are not displaying any error messages neither is the html content in the page displayed. I have no way of knowing whether my program is accessing the MySql database.

2. I need to know the necessary coding to convert ordinary data gathered from the databse to graphs/pie charts etc.
   Can this be created in mysql and called up by PHP? If so how?

3. For the global session variables: I give access to individual modules according to password. But the Adminisrator of the system gets blanket access to all modules. How do I code Session variables to accept the logged in user or the Administrator ?

these are very broad questions. any php tutorial might help you to narrow them down if not answer them altogether.
