maryfran:

I don't know if this will help, but this a "solution" I used once.

// destroy all session data including login -- the user can login 
again to make sure everything is OK


// bye bye cookie
if (isset($_COOKIE[session_name()]))
   {
   setcookie(session_name(), '', time()-42000, '/');
   }

 // and finally
session_destroy();

header("location:http://");
exit();
?>

Cheers,

Unset the variable. Session variables (as far as I know) will persist as
long as the user keeps open his browser, or until they time out. But you
can do unset($_SESSION['myvar']) to unset a particular variable at any
time (assuming you have previously called session_start()).

if this is on a server with low traffic, e.g. a development or test server,
it could be because of the way the garbage collector works. it's explained
in the manual.
