This is a really good question. All I'm looking for is to eliminate breaks in the logics of php. It's not very logical, that you can tread an object like an array to get it's slots but you have to call get_class() to get it's instance name... I can live with the way Boris sketched. BUT I want php to take exactly one way. Eighter an object can be used like an array: $obj = new foo; echo $obj["slot1"]; echo $obj["_CLASSNAME"] ( => obj ) echo $obj["_PARENT"] ( => NULL) echo $obj["_CHILDREN"] ( => NULL) or it behaves like a black box: $obj = new foo; echo get_class($obj) ( => obj ) echo get_parent_class($obj) ( => NULL ) echo get_child_class($obj) ( => NULL) echo get_class_vars($obj) ( => Array ( name => value ) ) You have started with get_class(), why not follow that way?
