RE: [PHP] Using unset with $_SESSION

Then there's session_destroy() too. If I ever suggest something that seems correct on the surface, but there's a good reason to use something else, even in particular cases, feel free to let me know. I think I know PHP fairly well, but it's so flexible and there are usually a dozen ways to do things, I find a way that work and use it. I figure if you want to get rid of all your session data, session_destroy() would do that. Guess you'd have to do another session_start() after that though, wouldn't you? Hmm.. See what happens when I use my brain? -TG > -----Original Message----- > From: trlists@clayst.com [mailto:trlists@clayst.com] > Sent: Wednesday, January 28, 2004 8:33 AM > To: php-general@lists.php.net > Cc: Ford, Mike [LSS] > Subject: RE: [PHP] Using unset with $_SESSION > > > > > Shouldn't unset($_SESSION) work? > > > > No. The following Caution appears in the manual (at > > > > http://www.php.net/manual/en/ref.session.php#session.examples): > > > > Caution Do NOT unset the whole $_SESSION with unset($_SESSION) as > > this will disable the registering of session variables through the > > $_SESSION superglobal. > > Thanks -- I have to say I missed that one! > > Thanks for noting session_write_close() as well.
