That was what I thought also. However just to add to the confusion: I
think require'd files were evaluated no matter what back in PHP4. Even
if they were part of a conditional. At least that's my recollection of
it; I haven't used PHP4 since 4.3.2 ;)
Bottom line: I always require_once at the top of a file for any files
that I will require. No sense in doing anything else if the required
files aren't there. For conditionally including files include_once()
has always made the most sense to me.
