Indeed. I've only ever used session_destroy() as the last statement
before quitting the page, so I never noticed. Seems a bit crap, after
all, you're asking it to 'destroy' the session, does anyone have a use
for destroying it and _still_ retaining the variables until script end?
I never destroy a session. Rather, I unset variables which are no
longer needed. Destroying a session might make other pages start to fail
because of session variables they use.
And maybe the site doesn't have this potential problem now - but what
about later? It's things like this which take hours (or days) to track
down.
