Well, it depends on the context in which you detect the error.  During
unit testing with PHPUnit2, you indicate failure with a call to
PHPUnit2_Framework_Assert::fail("error message goes here").

If a bug gets into a production system, it's a lot harder because you
need to think of what's sensible and how much trouble you get into by
trying to continue after the bug.
