I find this bug pretty irritating too. In my opinion
empty() shouldn't behave this way, or at least like Jorma
said, it should be mentioned in docs or some other way to
check if objects are empty.

No, I'm not using compatibility mode. If this is wanted
behaviour it should least be mentioned in the
documentation. I still don't understand why empty() have
to behave that way. Since that makes perfectly good
function for a good purpose go to waste on objects. Is
there going to be some function for checking empty
objects(no methods or properties) or do I need to
implement that myself?

Does this also happen in zend.ze1_compatibility_mode? This was changed
for non-compatibility mode with the change of moving objects to
handles. As far as the new OO model is concerned objects are always
handles, they are always true and they aren't empty. This is due to
objects being an entity of their own now and not just a different
syntax for accessing an array like structure. Just an example of why
empty() might not make sense with objects is how you'd expect it to
work with private/public/protected members.

Is this true Andi?

Description:
------------
Empty() does not return true on empty objects. My
understanding is that object that does not have methods or
properties is empty(am I wrong?).
Someone reported same thing on PHP 5 RC2 and it's still
open w/o comments http://bugs.php.net/bug.php?id=28502
Reproduce code:
---------------
<?php
class nuthin {
}
$bar=new nuthin;
$foo=new stdClass;
echo empty($bar);
echo empty($foo);
?>
Expected result:
----------------
11
Actual result:
--------------
nothing aka empty page
