Hello

I've been into this problem for a while already, and have asked some questions about it here Stackoverflow. I've got some advice, but I just can't understand it. Could someone provide me an example of classes working smoothly together.

I have 3 (maybe more) classes:

mysql
user
alerts

As I said, could someone provide an example, so these classes could use functions from each other class, e.g. user could use mysql's functions. I'm asking for an simple example, for learning-purposes.

And please, no google-suggestions or links to other questions. I've tried to search this for a while already. No success, though.
