Catching multiple exception types in one catch block

I'd like a cleaner way to obtain the following functionality, to catch `AError` and `BError` in one block: try { /* something */ } catch( AError, BError $e ) { handler1( $e ) } catch( Exception $e ) { handler2( $e ) } Is there any way to do this? Or do I have to catch them separately? `AError` and `Berror` have a shared base class, but they also share it with other types that I'd like to fall through to `handler2`, so I can't just catch the base class.
