New Comment:
I ran into this today with PHP 5.1.6. I spent most of the afternoon
trying to figure out why my vars were coming back after a header()
call.
One might suggest that this isn't a bug and that this behavior is
described in the docs (the session_unregister page for example). I
would disagree with this. This behavior is very quirky and completely
counter-intuitive. It would be much better for unset to behave in a way
that you would expect, i.e. to unset a variable (or element of a
variable) so that it stays unset, regardless of whether that variable
happens to be $_SESSION or not.

It doesnt clear it, all variables stay intact as they were when the
session started. It clears it in the current execution of the script,
but the next time the page loads all the variables are back as they
were before they were unset call
If i make any changes to session variables AFTER ive tried to unset one
they are not saved in the session on the next page load
Its as if the session doesnt save, even forcing the save with
session_write_close does not work

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.
>This should clear the session.
But it does ... instead?

replacing unset($_SESSION[$key]) with session_unregister($key) has the
desired effect -- which your not suposed to use according to all docs.

Description:
------------
For some reason unseting session variables is stopping php from saving
any session variables. The code below should clear the session but it
isnt, this code worked fine on 5.1.2 on a freeBSD box. Also ive noticed
that if i make any changes to the session variables (ie: adding new
ones) they dont get saved in the session either
Reproduce code:
---------------
<?php
session_start();
foreach($_SESSION as $key=>$value)
{
unset($_SESSION[$key]);
}
?>
Expected result:
----------------
This should clear the session. Also, any other changes made to the
session arent saved either (ie: creating more session variables
