Try this after that print:
print is_array($_SESSION['categories']);
You should get a 1 -- if you don't, try this:
print gettype($_SESSION['categories']);
You should get "array" but if you don't, there is something strange going
on! If you get "string" though, do this:
print strlen($_SESSION['categories']);
If you get "5", then the variable might be a string with the contents
being the word "Array". Pretty doubtful, but we're being thorough here.
