Subject: Re: [PHP-DEV] __Destruct() functionality
From: helly@php.net (Marcus Boerger)

Hello Gareth,

__destruct will get executed during request shutdown after the
communication has been shutdown. The only way to be able to write
from within __destruct is to deinitialize it at the end of the
script and therefore before the request is being finished. To
do so you can use 'unset($object);'

regards
marcus
