This limitation gave me a new idea! A Runtime that wasn't only for PHP, it was for all languages that can talk to C (Programming Language)
And now, I'm here to introduce you to this, you and the powerful runtime called OLSRT!
You can do anything (Actor, Channels, Event Loop & Poller, HTTP, Parallel, Promise & Futures, Streams, Timers, TLS, and especially WebSocket) in all languages!
If you want more about it, see Github: https://github.com/OverLab-Group/OLSRT
