Please leave this bug closed!
empty() has a different meaning than the one you seem to expect.
Objects can never be empty!

simplexml_element Object
(
[foo] => simplexml_element Object
(
)
[bar] => Array
(
[0] => s2
[1] => s3
)
)
[foo] looks empty to me?
Or maybe there are private properties that I can't see? If so, should
empty() return true if an object only has private properties?
How else can we tell if an SimpleXML object represents an empty tag?

The object is not empty. No bug here.

Changed this to "Zend Engine 2 problem" because it seems empty() should
return true if an object has no properties:

Description:
------------
This bug/feature request has some relation with bug: #25640.
I've loaded XML into a simpleXML object. SimpleXML currently loads
empty tags (e.g. <tag />) as empty SimpleXML objects.
With the SimpleXML object I wanted to use the following code to find
out whether a tag has child tags or not:
if (is_object($SimpleXMLObjectNode)) {
// $node has child tags
Unfortunately this doesn't work very well since this code will think
that empty tags have child tags too. (Since empty tags are loaded as
objects)
Therefore I thought it would be a nice feature to be able to find out
whether an object is empty or not. Something like:
if (empty($object)) {
// Object is empty
}
Reproduce code:
---------------
<?php
$xml = '<wrapper><foo></foo><bar>s2</bar><bar>s3</bar></wrapper>';
$t = simplexml_load_string($xml);
print_r($t);
if (empty($t->foo)) {
echo 'Tag is empty';
} else {
echo 'Tag has contents';
}
?>
Expected result:
----------------
Tag is empty
Actual result:
--------------
Tag has contents
