please use the same construct as before (foreach($_POST as...)), as =
relying on $HTTP_POST_VARS is hopelessly outdated.

Which will show you nothing about the NULL status. NULL is a strange =
beast, an empty string ('') or false will also print nothing to your =
screen, doesn't mean it is NULL. All values arrived by a POST are a stri=
ng =
by default, and a string cannot be NULL, it can be empty though, not the=
=
same thing. NULL is actually a type of it's own (next to strings, =
booleans, integers, floats etc.).
