Hi,
Just kind of curious what people think. In your opinion,
should a function avoid output? What I mean by that, is should a
function on "do something" without having echo or printf commands in it?
This is something I've been thinking about lately to improve my
programming style. Opinions?

Most functions I use don't output anything, but there's always going to
be a case where a rule must be broken.
