Thank you for help. I apologize for asking such a poor question. I've a
simple one to follow up with: how do you say "not" in regex? Is it "^"?
I've decided that all I want to do is make sure there are no letters in
the input. Is it right to say this:
$pattern "[^A-Za-z]";
$match = preg_match ($pattern, $subject);
This comes back true if there are no letters in $subject, yes?
