So how can we protect our PHP application scripts when installing locally for a client?

one text

Question: There should always be a way to protect your intellectual PHP application when you are running/installing it locally for the client unlike it be cloud or SAAS application on your own server.

Is there a tool that can encrypt the entire software application and still run perfectly locally or even in the cloud?

I have tried tools like; PHPLockIt, https://www.phplockit.com/

PHPLockIt works fine but I later realized it can be decrypted on this site: https://www.unphp.net/
