[GRLUG] What's Z + 1

[Justin Denick]

Depends on what you're counting with.

I needed to loop over [A-Z] to make some anchors and stumbled across
something interesting.

for ($i="A"; $i < Z; $i++):
  echo($i);
endfor;

Gives ABCD{..}XY

for ($i="A"; $i <= Z; $i++):
  echo($i);
endfor;

Gives ABCD{..}XYZAABB{..}

So I'm using
for ($i="A"; ($i <= Z and $i != "AA"); $i++):
  echo($i);
endfor;

This produces the desired results.

>From what I understand the default php behavior matched perl in that Z++ =
"AA" not "]" as it would in C (so I 've read)

Is there a better way to do this?
