Re: Using unset with $_SESSION

However, I'm still mystified as to why unset($_SESSION) not only doesn't remove old data from the sesison file when the script exits, but prevents the new variable I create after that from being saved. Perhaps $_SESSION as created by PHP is special and is tied to the session storage, whereas if it is destroyed with unset and then recreated that link is lost. That would explain the behavior. ---------- Tom Rawson
