I don't know what you experienced with __clone exactly, but maybe you wanted the class to allow accesses only from instances that have the same interface as the one being invoked. If so, my suggestion is to let those methods take a parameter that holds a caller instance and filter the accesses to it by the condition applying "instanceof" operator to that instance. p.s. A predefined variable like "$that" which indicates the caller instance would be what you want?
