Hilarity will not ensue. There are some good use cases for them as others have stated, but I'd recommend staying away unless you really need it. I've only ever used dtors for closing query results and gd resources. Trivial stuff to just try and lower the memory usage but isn't really necessary. In general though I stay away from them as most of my code is front-end meaning everything is tore down at the end of the request anyways. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
