How is this different from just catching all Exceptions? (catch Exception e)

Yeah, I don't think it is any different. I would say that the main benefit of the PEAR_Exception class is that it provides support for observers which can handle logging (or even immediate death). It also provides support for nesting exceptions, which is useful. I think the value of PEAR_Exception is in these features & not in the "namespace" that it provides. I'm curious to know what your take on Exception-based error handling is, Chuck. From the parts of Horde I've seen, it seems like you're in a perfect position to comment on PEAR's use of Exception in the long run, given the extent to which Horde makes use of PEAR libraries in a many-layered framework. My impression was that it would be a big benefit to the Horde framework. Hans
