I’m trying to create a custom app for shopify by entering this command into the terminal:
shopify app create php
and after specifying the app name and selecting store, I get this error:
PHP is required to create an app project. For installation instructions, visit:
https://www.php.net/manual/en/install.php

I understand that this error indicates a lack of php, but where should I set the language of php? on my computer?
I’m new to app development in shopify. And usually, I make plugins or server-side app, but this error is new to me.
Please tell me what I need to do.
Thank you.
