How can video calls be implemented using PHP on the back side?

Question

JavaScript

Hello! I want to implement video calls on the site. Started practicing NodeJS the other day . As far as I know, it is more convenient to implement this on NodeJS, I have not encountered such a task before. I would like to write this (Video chat roughly speaking), exactly the back-end in PHP. Please enlighten me how can this be done?
Thank you very much in advance!!

Most likely, what you practiced is called webRTC.
NodeJS is completely optional here. The main thing is that there would be STUN / TURN servers for laying the route.
If you are interested in web sockets in PHP, then yes, these exist and function normally.
