Bad idea. Every instance of the class will then attempt to
define the same set of constants, producing errors...

Can you please post some of your code?

Cheers,

Is this true? You can't _re-define_ constants but it wont produce an
error if you attempt it (it just wont work). Or am I wrong?

It porbably will if you have error_reporting(E_ALL) set...

What's wrong with putting the defines in global scope in the class source
code? Presumably, the whole point of the constants is that they can be
used by the code using the class, so it wouldn't make sense to hide them
inside the object's scope...

What exactly are you trying to achieve? Might make it easier to see
what's happening!

Yup. Dead right.
