It returns TRUE on an instance of ArrayObject or an implementation of ArrayAccess. It never calls offsetGet() on the extended ArrayObject. Test script: --------------- <?php class ArrayObjectChild extends ArrayObject { public function offsetExists($offset) { var_dump('Called: '.__METHOD__); return parent::offsetExists($offset); } public function offsetGet($offset) { var_dump('Called: '.__METHOD__); return parent::offsetGet($offset); } } $object = new ArrayObjectChild(array('foo' => '')); var_dump(empty($object['foo'])); Expected result: ---------------- string(38) "Called: ArrayObjectChild::offsetExists" string(35) "Called: ArrayObjectChild::offsetGet" bool(true) Actual result: -------------- string(38) "Called: ArrayObjectChild::offsetExists" bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=66834&edit=1
