Note Submitter: the_mindflayer@operamail.com ---- Session variables and unset() do not mix. Somewhere between v4.0.6 and v4.1.2 something seems to have changed with the way unset() affects session variables. I may be totally wrong, but this is what I see. -------------------------- session_register("ABCD"); if ( empty( $ABCD ) ) { $ABCD = array(); } // Miscellaneous nasty stuff going on in here... // code code code, type type type // We decide we want to clear the variable. // (eg: login page and we want to reset permissions // before we assign new ones) unset($ABCD); $ABCD = array(); -------------------------- At this point, in 4.0.6, $ABCD appears to be the session variable we defined earlier. Any changes made to it WILL show up in the session. At this point, in 4.1.2, $ABCD appears NOT to be the session variable we defined earlier. Any changes made to it WILL NOT show up in the session.
