Bug description: Empty function fails when examining property of object
accessed through __get
Description:
------------
Empty returns false whenever a property of an object is accessed through
__get. This problem has been reported before. The answer that "it's a
feature" is entirely bogus - Either return the right value or throw a damn
error but don't do nothing and leave people to wonder what the Hell is
going on with their script. I just lost two full days to this "feature" and
I'm not amused.
empty(someFunction());
throws an error. If this bug is too much trouble to fix set it up so
empty($object->property);
also throws an error when a __get has been set.
Reproduce code:
---------------
class foo
{
protected $data = array();
public function __set($element, $value) { $this->data[$element] =
$value;
}
public function __get($element) { return $this->data[$element]; }
}
$bar = new foo();
$bar->cat = 'meow';
empty($bar->cat); // returns false, as expected.
$bar->cat = '';
empty($bar->cat); // returns false, should return true.
