The only time I've seen anyone use $code is in TYPO3. Their coding standards say that any time you throw an exception, you use the current timestamp (determined manually) as a code. That way there is a globally unique code regardless of exception type that can be grepped to find the exact line it came from. I am not saying this is a good strategy, just that it's the only time I've seen $code used in the wild... --Larry Garfield
