Obfuscation of PHP code. Or using the license check API. What options would you suggest?

Question

PHP

One copy of the script for the customer will cost from 100 thousand rubles. It's a pity if they dump it. How do you protect your work?

Answer 1

NO WAY.
NO WAY.
And again NO.
If your project is of interest to crackers, it will still be hacked . The
easiest way is to put a password on the files. If they leak - you can safely complain to the court about the client

Answer 2

How do you protect your work?

No way.
Obfuscate and package in native php extension.
+ fasten the licensing system.

Answer 3

SaaS.

Answer 4

PHP is not suitable for selling licenses, for such a price the code is not in PHP and with good protection will be broken. But to the PHP topic, the only viable option is to keep this code on your servers and give access to its api.
