Having same problems. I also believe that the modules should be shutdown after __destruct() I am wondering if this is going to be fixed or is it not being classified as a bug? helly@php.net seems to think it's expected behaviour but I never thought it would be which is why I am here after googling about it. __destruct() is a user definable method. All aspects of user programs should have all the resources available to them from the start of the script right through to the end. Refcounting of whatever it was that they suggested is not an option, in fact, I don't even know what that is. -Mikey ------------------------------------------------------------------------ [2004-06-15 11:07:03] dcaironi at yahoo dot com I agree with fschaper. The ability to modify the $_SESSION variable in the destructor could be very useful, for example to have your class automatically serialized in session; this, with a factory pattern (getInstance method, that unserialized the class if exists in session), allow to have a "session object", sort of. for example Class Test{ function __destruct(){ $_SESSION['test'] = serialize($this); } static function getInstance(){ $instance = unserialize($_SESSION['test']); if(!isset($instance) || !is_a$instance,"test")){ $instance = new Test(); } return $instance; } } Actually, this was possible with php 4.x using register_shutdown_function, that (in fact) allows to simulate the destructor behaviour... ------------------------------------------------------------------------ [2004-06-15 11:06:59] dcaironi at yahoo dot com I agree with fschaper.

I wrote a short patch for this and it works out fine (That does not mean however that it does not break something ,) ). http://www.intux.org/download/patches/patch_php_cvs_01_06_04.rar ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
