Async PHP playground

Purpose of this repository is to demonstrate how to use amphp/amp to run multiple child processes in parallel.

As bonus, it shows how to pass data from child processes to parent.

Usage

Just run php run-multiple-processes.php

Expected results

It runs 10 times script.php that has sleep(5) inside and we expect all of this to finish within 5-6 seconds.
