Exception Handling

Examples of exceptions in a web application are model or data layer errors such as "Cannot connect to the database" or user errors such as "Email format incorrect". RawDev offers a simple consistent way of raising these exceptions so that they can (a) be properly logged when necessary and (b) be properly displayed to the end user.

RawDev simply extends the existing PHP Exception with the RException object. Mainly, the added functionality is that you can raise an error with a type (e.g. "division_by_zero"). In addition you can specify a message with parameters (such as used in sprintf). This is (a) handy for the programmer and (b) allows for different languages (i18n) down the road.
