How to use socket in phalcon well you have to make it work yourself, there is nothing prepared for you.
what deffierent about php socket , websocket and swoolefirst what is websocket can be found here: https://kaazing.com/websocket/ ( basically instant ajax request )
well ... i know https://socketo.me/ ( Rathcet ), and swoole are basically the same thing, they create a service that listen for events ( and they have their own events ), if you check their hello world you can see those events and get the idea.
Phalcon is php framework writeen in C ( which makes it super fast ), and basiccaly same applies for swoole .
Well this is what I know, maybe someone can correct me if I am wrong
