Thanks, Adam.
I think I resorted to using it because of some error or other warning I got
with special HTML characters, and it probably applied to THAT situation, but
clearly not to THIS situation; over-thinking, I guess.
Your explanations resulted in warning-free code.
I'll remember to read the changelog too to make sure that the syntax applies
to the current version. I use 5.2 because I think that is the latest
version produced as a ready binary for Win 7 running Apache 2.2, but then
again, I could certainly even be wrong on that as well. :)
