Library -Object - Hydrate

Thank you ! you guys save my day.

It works then and I'll be able to continue.

I'm beginner so I'm going in lots of different ways. It seems my way of thinking is not that wright. I'm trying to learn PHP by creating my own application.
The idea is to create to member pages. The member will be able to create some tasks into the database depending some projects.
My idea is to have one class as explained for :
- Member
- Task
- Project

Using this way I'll be able to create a session based on the Member object. I'll be able to easily get information from my member during all the session and for creating all the other objects.

Is my logic right ?
Do you have any docs or examples to share in order to construct the basic correctly ?

I know I'm way before the start already but I keep going and try to understand it! Not an easy part.

Thank you,
M.
