Hi,
I think I once knew a PHP5 interface, which forces a class to implement
a function empty(). If an object $myObject implements this interface, it
should be possible to call empty($myObject) as it seems to work with the
interface "Countable", which does the same for count().
The problem is I didn't find such an interface in any doc I found so
far. Does anyone of you know such an interface, or did it ever exist?
thanks,
Norbert
