New Comment:
session_unset() will delete the variables from the global scope. So, instead of
global $a;
session_unset();
$a = "foo";
you need to use this:
session_unset();
global $a; # establish link to global variable
$a = "foo";

I adopted most of this little script from user feedback in
the session_unset()'s annotations. I ran into the same
problem, and think that it demonstrates it well.
<?php
function
dummy()
{
global $a;
session_unset();
$a= 'foo';
echo "<br>2. ".session_register('a');
}
session_start();
$a= 'foo';
session_register('a');
echo "<br>1. $a";
dummy();
echo "<br>3. $a";
?>
If you run it, you'll see that, even though the second
session_register() returns TRUE, $a is not registered again,
and remains unset.
This bug does not allow me to be paranoid enough coding a
login-protected website.
Thanks.
