Bug description: Destructor is called to late, unset do not work
Description:
------------
Destructor is not called to late. If you use a singleton pattern unset
does not work, because there exist a private static reference for the
object.
Why is the destructor called so unreliable?
Is such a singleton pattern not possible in PHP?
Or must the static $instance be public, inorder to unset it manually? (Not
a nice solution?!)
Reproduce code:
---------------
class Session { //Db Session (Singleton)
static private $instance = false;
private function __construct() { }
public function __destruct() {
$this->sessionWriteClose(); // e.G. store session data
}
static function instance() {
if(!Session::$instance)
Session::$instance = new Session();
return Session::$instance;
}
}
$OBJ_SESSION = Session::instance();
unset($OBJ_SESSION); // Does not work, because of the static private
$instance
