How can PHP be used to create a password-protected area with different levels of access for users?

To create a password-protected area with different levels of access for users in PHP, you can use session variables to track user login status and permissions. You can store user credentials in a database and verify them during the login process. Once authenticated, you can set session variables to grant access to specific areas of your website based on the user's level of permissions. 

<?php
session_start();

// Check if the user is logged in
if(isset($_SESSION['user_id'])) {
    // Check user's access level
    $user_id = $_SESSION['user_id'];
    
    // Query the database to get user's access level
    // $access_level = queryDatabaseForAccessLevel($user_id);
    
    // Check user's access level and redirect accordingly
    if($access_level == 'admin') {
        // Redirect to admin area
        header("Location: admin.php");
        exit();
    } elseif($access_level == 'user') {
        // Redirect to user area
        header("Location: user.php");
        exit();
    } else {
        // Redirect to login page if access level is not valid
        header("Location: login.php");
        exit();
    }
} else {
    // Redirect to login page if user is not logged in
    header("Location: login.php");
    exit();
}
?>
