[PHP-DEV] empty() II From: Jan Legenhausen (jan <email protected>)
Date: 05/30/98

I just discovered that empty($test) also says "TRUE" for $test=0.

Now i think i begin to understand what empty() is good for... :)
It gives TRUE if the given value for that given type corresponds to the
value of 0. Unset variables are supposed to also have a value of 0. A
string value of "0" isn't considered as empty - but "if ($test)" results
in FALSE (is this intentional?).
For me, this all makes things not _so_ easy, if all i want to ensure is
to catch POSTed form vars and distinguish between fields not filled and
fields filled with "0"...

yours, Jan
