What are some potential pitfalls of including a copyright notice in a PHP script that users can easily edit?

Including a copyright notice in a PHP script that users can easily edit can lead to the notice being removed or altered without permission, potentially infringing on the original creator's rights. To prevent this, you can encrypt the copyright notice within the script using a simple encryption algorithm. This way, even if users can access and edit the script, they won't be able to easily modify or remove the copyright notice.

<?php

$copyright = "Copyright © 2021 Your Company. All rights reserved.";
$encrypted_copyright = base64_encode($copyright);

echo base64_decode($encrypted_copyright);

?>
