With PHP you can just start typing in your file and produce output. Even with lightweight frameworks like Flask there is boilerplate.
And if you really need php-fpm (which you should, anyway), at least in Ubuntu (never set up on other distro), the boilerplate nginx config is there.
Neither mod_php nor php-fpm is related to the built-in server though. Both are designed for production.
