HTTP authentication logout via PHP
To log out a user from HTTP authentication using PHP, you can use the header
function to send a "WWW-Authenticate" header with a value of "Basic realm=realmName" and a 401 status code. This will cause the browser to prompt the user to enter their credentials again.
Here's an example of how you can log out a user using this method:
<?php
header('WWW-Authenticate: Basic realm="realmName"');
header('HTTP/1.0 401 Unauthorized');
You should also clear any session data that you may have stored for the user, to ensure that the user is logged out from the application as well.
<?php
session_start();
session_destroy();
