Hello, Pavel. PHP has the Parallel library, which already allows you to do quite a lot. But you probably already know about it. From the multithreading perspective, there is also the following research: https://github.com/true-async/multithreaded-php/blob/main/mm-en.md https://github.com/true-async/multithreaded-php/blob/main/mm-ru.md
This article discusses a direct analogue of the architecture used in Node.js. I hope that this year we will be able to move TrueAsync forward, and along with it possibly introduce convenient multithreading as well.
