Thats because it was never intended :) The engine calls __destruct() right before the GC frees the object, but unset() only decrease the refcount. The next time the GC runs it will call the destructor and everythings fine > > When unsetting an object, php doesn't automatically remove references to > other objects, and you need to manually call the __destruct method where > you can remove any references to other objects. > Why? When the GC removes the object from the memory (which might be slightly later) it also removes the references to associated objects and when their refcount reaches 0 they will get removed as well.
