PHP API & Next.js?

Question

API

Can you please tell me if it's okay to combine API written in PHP with Next.js?
I need SSR, I'm considering 2 options:
1. Write an API in PHP using Next.js for the front application rendering layer.
2. Embed some Express.js into Next.js (custom server) (but for me personally, working with Node is difficult).
I specialize in PHP (Symfony) myself, and would like to write an API in it, but I'm not entirely sure how correct it is to combine PHP with Next.js. As I understand it, getInitialProps() - will just access the API on the puff?
Maybe someone has already written a similar project, or there is an open source example, please discard)

Answer 1

next.js supports API routes out of the box.
