I'm pretty sure that programs outside a session should never have access
to the session bus as that would have severe security implications.
Instead, I think what you want to do is to make PHP emit signals on the
system bus (you don't even have to own the service all the time) and
then your client in the desktop session can pick those up and display
notifications.
