function validateUser($username, $password) { // check if user is valid if ($username === "admin" && $password === "password123") { // redirect to admin dashboard redirectAdmin(); } else { // show error message echo "Invalid username or password"; } }
function accessControl() { // check if user is logged in and authorized if (!isLoggedIn() || !isAuthorized()) { // redirect to login page header("Location: login.php"); exit(); } else { // redirect to admin dashboard redirectAdmin(); } }The redirectAdmin function or method is likely part of a PHP package or library that provides utility functions for web development, such as user authentication, authorization, and access control. The specific package or library would depend on the developer's preferences and project requirements.
