why don't you go and read up on request shutdown issues and __destruct() -
there is plenty in the archives of the internals@lists.php.net mailing list;
it's many times more complex than you might imagine (imagine 2 'chicken & egg'
problems in tandem - oh and a solution is needed to handle circular references
properly so that object refcounts behave the way you would expect with regard to
triggering dtor functions). bottom line don't hold your breath if you want the
__destruct() and shutdown code/beahviour changed.

* tell us why do you want to control the descruction order of your objects?
* it might help someone offer a viable alternative

btw: stating a new post/thread by replying to an existing one is very bad
form - given that you have knowledge of ctors/dtors in php your skill
level is probably greta enough that you should know better ;-)
