There is just nothing more repeatable or common cases than "resource not
found", "method not allowed", "access denied",... They are all non
exceptional cases better handled without exceptions and with clean APIs
reflecting the business logic of the application.
I think part of the problem may be that non-trivial examples require
rather a lot of context. An example that comes to my mind is if an
application is combining a bunch of different libraries, and calling
them all in sequence:
try
{
$fooService->doStuff($data);
$barService->doMoreStuff($data);
$bazService->doDifferentStuff($data);
}
catch ( FooException | BarException | BazException $e )
{
// We don't care which library threw the exception, the action is always
the same
throw new AppException($e); // Hide which libraries we're using to
implement the function
}
