Installing a basic PHP site

I like the fact that MIAB is straightforward and doesn’t over complicate things for us UNIX noobs.
Having said that, I’d really like to be able to load some PHP files from the “static website” portion of the server.
I realise that this is slightly contradictory, but it looks like the “static” folders don’t allow php files (as I get a 403 error when trying to browse to them).
I was under the impression that NGINX comes with PHP/FastCGI. I’m not interested in databases/SQL, but the PHP side of things would be very useful. Is it straight forward for a noob like me to enable?
