Robert Basic has posted a follow up to his first post about using DBase in PHP in this new post. This new tutorial shows you how to listen to signals sent to the waiting PHP script.

The good part is that not can we only call different methods against Pidgin's libpurple API, we can also listen to different signals on different events, that are sent via Dbus. [...] The PHP Dbus extension allows us to watch for one exact signal on an interface, or for all signals on an interface. Of course, we can add watches on multiple interfaces at once.

In his example he shows how to set a listener on the session to watch for an incoming instant message from another source. Sample code is included showing how to set the listener on the interface and be able to tell when a message comes in (watching a $signal interface for an event). You can find more signal catching examples in his github repository.
