Generally, it would depend on when they were created. If they were created before shutdown stage and you try to access them in OB shutdown stage, it may be too late and the dtor may have been called for them already. Doing too much stuff on shutdown is not really a good idea, as you can not rely on resources being there. If you really need to do something on shutdown, I'd advise register_shutdown_function() as it is called first, before anything is really shut down. Relying on OB handlers shutdown is not a good idea as by then at least part of the shutdown happened. If you do something with OB handlers, I'd propose to add a shutdown function that flushes the OB, so that you are sure everything is wrapped up while the engine is still in predictable state and not half-shutdown. -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/ -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
