[thelist] PHP: is_numeric... that's the question...

[Tris]

Indeed..
so using this:
return preg_match("/\d{1,8}/", is_numeric($usercode));
still doesn't work, I can enter a numeric string of 9 or more
characters and it's accepted? yet the {1,8} should stop at 8
characters right???

OHHHH, It IS finding strings of 8 characters within the whole string...

I started with this code:
=======================
	$codeLength = strlen($usercode);
	$codeInt = is_numeric($usercode);
	if ((($codeLength == 0) || ($codeLength > 8)) || (!$codeInt)) {
		return false;
	} else {
		return true;
	}
=======================

Should I just stick to that, or is there a way to do it with one line
and regular expresions?

Sigh...
is it Friday yet?
