What best practices should be followed when implementing access control for video files in PHP to ensure that only authorized users can view them?

When implementing access control for video files in PHP, it is important to ensure that only authorized users can view them. One way to achieve this is by using a combination of authentication and authorization techniques. This can involve verifying user credentials and checking their permissions before allowing them to access the video files. 

// Check if user is authenticated
if(!isset($_SESSION['user_id'])) {
    // Redirect user to login page
    header("Location: login.php");
    exit();
}

// Check if user has permission to view video
$allowed_users = array(1, 2, 3); // List of user IDs with permission
if(!in_array($_SESSION['user_id'], $allowed_users)) {
    // Redirect user to unauthorized page
    header("Location: unauthorized.php");
    exit();
}

// Display video content
echo "<video src='video.mp4' controls></video>";
