    Responding to Exceptions

    Hello everyone,

    I have set up some custom exceptions, and have managed to implement
    the proper responses to those exceptions. I have something like this:

    try {
    do something;
    } catch (ExceptionA $e) {
    response;
    } catch (ExceptionB $e) {
    response;
    } catch (ExceptionC $e) {
    response;
    } catch (ExceptionD $e) {
    response;
    } catch (Exception $e) {
    respond to unknown exception;
    }

    It's a little clunky though, because sometimes responses to Exceptions
    B, C, and D are the same. Is there any way to collect those specific
    exceptions together in a specific response situation? In other words,
    what I'd love to do is:

    try {
    do something;
    } catch (ExceptionA $e) {
    response;
    } catch (ExceptionB $e OR ExceptionC $e OR ExceptionD $e) {
    response;
    } catch (Exception $e) {
    respond to unknown exception;
    }

    I know I could catch Exception A, then catch the parent Exception
    class, then $e->getcode, and respond to the code in an if-else clause
    or switch clause. But is there any way to do this with the exceptions
    themselves, i.e. catch a group of exceptions together? Thanks.

      No, but you can derive B, C and D from the same class (BCD) and handle
      an exception for BCD.
