Subject: Re: [PHP-DEV] GMP and empty()
From: php@marc-bennewitz.de (Marc Bennewitz)

Hi,

because in my world the following operations should be the same:
(expect that "empty" doesn't trigger a warning in an unknown variable)

$v = gmp_init("0");
if (!$v) {}
if ($v != true) {}
if ($v == false) {}
if (empty($v)) {}

... so in my world "empty" should be handled the same as "$v == false"
and such comparison operation is possible to define by the GMP object if
it's not already.

Thoughts?

Marc
