Is it efficient to achieve asynchrony from PHP or is it better to use a bundle with NodeJS?

Question

PHP

What technologists will you advise, what articles to read on the topic, I will be grateful to everything

Answer 1

Reactphp + libevent and your little node.js is ready. It doesn't really make much sense unless you have too much php code to use, but there are solutions here too. Depends on the task.
In terms of the efficiency of asynchronous gizmos, golang is more efficient.
