Broadcasting from php

[cvele]

In documentation you state

"Try pairing up a Periodic function with a Custom Topic handler to perform actions on a set of clients connected to a certain topic."

I'm unable to find a way to broadcast a message from periodic in order to send message to connected clients.

Is there a way to connect to certain topic from php? (ideally in periodic class)
