You're insetting the variables within the chout() function only This has no
effect on
the local copies as they are not in scope here. You have successfully
destroyed the
session so when you refresh they are unset.
What I do with sessions is keep them all within a session array so you can
then destroy
the session locally by unsetting that array. If I have a function that I
want to change session
variables at all I make it take the session in as a parameter and pass it
back as the return value.
