You are replying in a thread where you have not even read the title, or even posts.
You answer that you don't even know what it's about.
Do you know what the PHP CLI version is?
If you want to change PHP version to use PHP 7.1, it's very simple:
Left click icon Wampmanager -> PHP -> Version
In the basic version of Wampserver 3.1.0, there is PHP 7.1.9. If you want another version, you install a PHP addon that you will find here [
