Is it just me or are we missing a way in the language to check if a
variable that has been set to NULL exists or not?
is_null() on an unset variable throws a NOTICE.
$var === null throws a notice.
So, you have to use isset()? But, ah,
$var = null;
if(isset($var))
yields false.
Is array_key_exists("var", $GLOBALS) the only solution to this problem?
Seems silly.
perhaps an var_exists() function is needed to fill this hole?
