Well, you have 'something' on 'a' server and 'it' doesn't 'work' without sp2.
That's like going to a garage and saying: "I have 'a' car and when I do 'something' with it, nothing happens."
How about telling us a bit more about what you're trying to do with PHP and databases that doesn't work without sp2?
(and why is it a problem anyway, sp2 is required, not optional)
