(PECL weakref >= 0.1.0) Releases a previously acquired reference public bool Weakref::release ( void ) Releases a previously acquired reference, potentially turning a strong reference back into a weak reference. The Weakref instance maintains an internal acquired counter to track outstanding strong references. If the call to Weakref::release() is successful, this counter will be decremented by one. Once this counter rea

(PECL weakref >= 0.1.0) Returns the object pointed to by the weak reference public object Weakref::get ( void ) Returns the object pointed to by the weak reference. Returns: Returns the object if the reference is still valid, NULL otherwise. See also: Weakref::valid() -

(PECL weakref >= 0.1.0) Constructs a new weak reference public Weakref::__construct ( object $object ) Constructs a new weak reference. Parameters: object The object to reference. Returns: No value is returned. Examples: Weakref::__construct() example <?php class MyClass {     publ

(PECL weakref >= 0.1.0) Acquires a strong reference on that object public bool Weakref::acquire ( void ) Acquires a strong reference on that object, virtually turning the weak reference into a strong one. The Weakref instance maintains an internal acquired counter to track outstanding strong references. If the call to Weakref::acquire() is successful, this counter will be incremented by one. Return
