I can see the confusion about PHP's case-sensitivity and how it mixes
and matches between case-insensitive functions/classes/(arguably even
constants), and case-sensitive variable names, for example.

Its naming rules are a little bit inconsistent in that regard. I just
don't see a point in making it completely locale aware. The fact that
you can do soefunc() and SOMEFUNC() and still invoke the same function
is a benefit. And I suppose for those using UTF-8 encoded function
names it might be convenient to make them case-sensitive as well. I'm
not going to argue that it's not. I'm just going to say that it
doesn't seem to be a significant problem.
