I have the same problem.

The reason is when you pass $_POST['postvar'] to a function and
$_POST['postvar'] is not set, PHP generates warning. Of course one could
turn off warnings and usually does, but in my opinion it's not a
solution. However checking everytime if variable (or array index) is set
before passing it to a function generates sometimes tones of similar
code which could be simply replaced with one elegant macro.
Maybe it's just a matter of programmer's habit, I feel lack of macros.
