Query about WWW-Authenticate: Basic and bad UserID/Password recovery

Show all headers | View raw

Per the samples I have seen in manuals and on the php,net site  I store the
header statements in a if(!isset($_SERVER['PHP_AUTH_USER'])) delineated
section.

I test the supplied UserID and Password to see if they are a valid pair. My
problem is that when they are not (right now I have a hard coded pair to use
in my testing) I issue an error message and have the user try again (by
having the page relaunched via a link). The problem is that the IF sees that
the UserID is already set (to the bad value) and thus will not reissue the
login menu. How do I invalidate the stored value so that the IF will return
TRUE and thus cause the menu to be issued? I tried adding a
$_SERVER['PHP_AUTH_USER'])=""; or a unset($_SERVER['PHP_AUTH_USER']); in my
error routine (with the link) I still do not get the the menu.

Please Help.

Thank you.
