Are you saying that the Session state is kept even after you close all
browsers?

Are you sure you're not using other cookies rather than Session data?

No it does NOT. They are valid as long as the script runs. A call to
$_SESSIONS=arra y(); after the session_destroy () clears the session
variables.

Does it HAVE to be that way around? I usually do it the other way
around: session_destroy then $_SESSIONS=arra y() and it works fine for
me.

If the original poster is doing this and still has problems; I would
suggest checking the session name on your logged in pages and also the
logging out page. Use the session_name() function to see this.
Personally I always use a custom session name for `security` purposes.

I was a bit ambiguous in my phrasing. I use the same order you do.
technically I don't think there's much against the other way around,
from a logical point of view I think 'yours' is the preferred.

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.
