It still boggles my mind that you'd want to even *do* all this when you have

a built-in array type that can do everything you've done about a zillion times faster...

1)I'm programing with php-oop for a few months. I need to know how to PHP work with references, class, ... . 2) I need data stucture like this: method add($object): append object (anywhere, position is not important) method remove($object): remove object method item($index): get object at $index with array??? There is a identical problem: deep recursion. Object1 have references to object2 across Object3 which have ... and vice versa. Function uniqid() (or microtime()) is quite good, but is not a clear solution. For example: class Storage { $container = array(); function add(&$object) { $objectID = microtime(); $object->__uniqueObjectID__ = $objectID; $this->container[$objectID] = $object; } function remove(&$object) { unset($this->container[$object->__uniqueObjectID__]; } function item($index) { $keys = array_keys($this->container); return $this->container[$keys[$index]] } } Grrr... to many problems: 1) adding variable to the third-party object 2) in remove() method: remove __uniqueObjectID__ varible from object or not??? 3) if exists __uniqueObjectID__ variable replace with new value or keep current value??? 4) Zend Engine 2.0 __clone() method: $obj = new MyObject(); Storage->add($obj); $obj2 = $obj.__clone(); Storage->remove($obj2); // Error: I want remove Obj2 not Obj1 and more... -- Ondrej Ivanic (ondrej@kmit.sk)
