$x++; # keep track of how many users have logged in
Actually, I think that's a poor comment, unless the text around it makes it make
more sense. I'd prefer to see something like:
$x++; # $x is number of users currently logged in, and we have a new o
+ne
Hmm. On re-reading your comment, I can't tell whether you meant
total number of users that have ever logged in, or whether it's a current
count. That's probably why I already flagged it as bad. {grin}
Even better would be to never use $x for something like that:
$current_users++; # we have a new one
That's a lot better.
