Are there any specific guidelines or resources available for implementing a secure logout feature in PHP while using htaccess for authentication?

To implement a secure logout feature in PHP while using htaccess for authentication, you can simply unset the user credentials stored in the session and then redirect the user to the login page. This ensures that even if the user's credentials are stored in the browser, they will be invalidated upon logout.

<?php
session_start();

// Unset all session variables
$_SESSION = array();

// Destroy the session
session_destroy();

// Redirect to the login page
header("Location: login.php");
exit;
?>
