Does anybody know any good tutorials for learning PEAR::'DB_DataObject?
I'm using the book PHP Anthology: OOP PHP solutions vol. 1
and I'm having trouble seeing how things work with this Database Abstraction Layering method. I was trained in using hard coded SQL which takes more time to do but the benefit is that you see what's happening very easily.

I can't understand how the layer abstraction code in this book's example work. So I would like some tips for tutorials on the Web where you can follow some more simple excercises.
