Hi Lukas, No, I don't think it would make our life easier. In your example, one is supposed to know that getTextValue will return a text value (supposedly a string), not an error object or I don't know what. So I don't think this would be useful, it's not a common practice in PHP code. Anyway, thanks for asking me. I hope you will keep up with your DB_OK idea. Bertrand Mansion Mamasam
