Wow, thats a very nice website you have. Some very clean examples,
though a bit more explanation might be needed for some. It contains
some things that every developer should know, especially PHP ones,
since most PHP devs aren't formally taught these concepts.
For the iterator pattern you should note that there is a native
iterator interface in PHP5 (several, actually), allowing you to iterate
over arbitrary objects using foreach(). Other interfaces are available
to allow array access with [], using count(), etc etc.
Might want to note that only the most recent versions of MySQL support
the really useful SQL features, too, simply because MySQL < 4.1 is
still so common.
A short blurb or links about database normalization could be helpful,
too.
