Nikos M.

This package can register and call handlers of events by name.

It can register callback functions that will be called when an event with a given name happens.

The package can also process events that are triggered and call all functions that were registered to handled the called event.

Besides the PHP version it also provides implementations of this publish and subscribe solution in JavaScript and Python.
