Here's a note, something mildly annoying:
If you use foreach() on an array that happens to be empty, you will get an error, so in cases where
you're building an array dynamically and the array might be empty, you have to test for
sizeof($array) > 0 before doing a foreach(). It would be nice if foreach() just skipped itself
for empty arrays, but it's not hard to test ... just more typing. :)
