classes are slower than functions. Remember php was not and is not (will not be?) designed for OO programming. its designed for web programming. now tools like a class::$db may be slower (like anyone will notice a difference cept in high crunch situations) it makes a lot easier for fexibilty. ie.. changing database servers down the line..
