You should not throw a PDOException from your own code. The possibility to use multiple catch blocks can give finer control over the response to certain types of exceptions.

With this customErrorMessage method, the output will be something like “Error on line (line number) in file (file name): Cannot divide by zero”, and it will give more detailed information in case we need to debug the exception.
