Parallel requests via rest api possible?

Question

API

Hello!
Is it possible to execute parallel requests in php?
Using Laravel, I wrote a parser for this parser, I wrote rest full api, if I simultaneously call a function via ajax on js, will these two requests be executed in parallel on the server?
If so, please write why this will happen, citing the facts for proof.

Answer 1

Parallel.
Because fpm has a lot of workers in the pool.
