I'd like to reopen bug report 2088 (I didn't know of
a better way than doing this), since the semantics
are changing between PHP 3.0 and PHP 4.0.

Is the string '0' non-zero?  I personally think so, as
it's not a number.  I know of at least one application (phpMyAdmin) which breaks because of this inconsistency.

If you're going to change the semantics of empty, I think
it would be a good idea to at least document it.

I am betting that this is bcz of the dynamnic tying.
Either way, marking it as "Misbehaving Function"

Note that:
<?

                               $name=0;
                                echo empty($name);
?>

prints 1 under php3 && 4.
