Answer 1

I know this is an oldy, but since it comes up high in both SO's own search engine and Google: a nice article about the relative performance of the methods mentioned by the OP can be found here: http://shwup.blogspot.com/2010/04/about-constants.html

Answer 2

I've used apc_define_constants quite a bit without any trouble - I've never tried hidef because of its 'alpha' status.
