Im confused about server side ??

So in demo you use php -S to spawn a php's own little server on 9001, but this seems to be able to only talk to one client at a time ? ie while one browser or tab is loaded, no others can connect, just get blank page with loading...

How do you think we should use this to push updates to multiple users at a time ?

Simply use FPM or Apache, and complex Swoole WebSocket Server.
