RE: [PHP] Which Regex library?

well, i would try this: ereg('([0-9]+\.){4}', $email, $res); I'm not sure if that will work, but your expression is definitely not correct. I would reduce it down to its most basic element, perhaps, and try that: ereg('[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+', $email, $res); If that works, then just use that. johnny p. > -----Original Message----- > From: Shawn J.
