Eric's exactly right, J. I started working with PHP about a
decade ago (yeah, I was one of the 1% or so that played around with
PHP/FI2 - and I still have a copy of it, actually). I really didn't
appreciate functions as much as I should have until the release of
PHP4, and like Eric said, it's not just for 'reusability' - it's also
for portability, centralization, extensibility, and a whole bunch of
other great words with expansive suffixes.
