It's not really confusing so long as you understand how PHP works. Each request
is brand new - nothing is retained from previous requests. The two variable
you're changing are set by PHP when the request comes in from the browser. The
fact you changed them in a previous request is irrelevant because 1) that
change was not communicated to the browser in any way, and 2) PHP doesn't
retain any data between requests [1].
If you've been coding assuming that changes you make to global variables are
retained between requests you must have been having some pretty frustrating
times!

Not really - this is the first time I've had something not work as expected.
That was said with my tongue very much firmly in my cheek, and so is this:
I've been playing with dynamite since I was 4 - hey, it must be a safe,
proper thing to do!
Just because nothing has blown up in your face yet doesn't mean it won't, and
I'm concerned that you might not actually see how important it is to make sure
you're using the tool correctly.

This may very well be the first time with this problem because I haven't
tried anything like this before.
That said - can you give me some pointers on how to do the JS solution?
I'm calling a script that is similar to the one I used to signon. It
sends out something like:
header("WWW-Authenticate: Basic realm=$realm");
header('HTTP/1.0 401 Unauthorized');
echo "<h3>You have entered invalid credentials<br>";
echo "Click <a href='$return_url'> here </a> to return to the
menu.";
exit();
when it doesn't detect the PHP_AUTH_USER or it is an invalid value.
So - to effect a signoff, what does one do? You said to use an invalid
value, but what do I do with that? How do I ignore the 401? Now I'm
getting the signin dialog and I'm stuck.
