This is an old revision of the document!
A couple of notes, saiiznte your request variables before pulling data directing into you code. Avoid using double quote for simple string echo as it is extra load on php parsing use single quote instead. Play with MVC type frameworks such as Zends framework to get familiar with design patterns. Nice tutorial for beginners but be warned, I had to fire a bunch of people recently who programmed like this go back to programming basics and learn popular framework methodologies.
