(PECL weakref >= 0.2.0) Updates the map with a new key-value pair public void WeakMap::offsetSet ( object $object, mixed $value ) Updates the map with a new key-value pair. If the key already existed in the map, the old value is replaced with the new. Parameters: object The object serving as key of the key-value pair. value The arbi

(PECL weakref >= 0.2.0) Returns the value pointed to by a certain object public mixed WeakMap::offsetGet ( object $object ) Returns the value pointed to by a certain object. Parameters: object Some object contained as key in the map. Returns: Returns the value associated to the object passed as argument, NULL otherwise.

(PECL weakref >= 0.1.0) Checks whether the object referenced still exists public bool Weakref::valid ( void ) Checks whether the object referenced still exists. Returns: Returns TRUE if the object still exists and is thus still accessible via Weakref::get(), FALSE otherwise. See also: Weakref::get() -
