Re: Getting the Leftmost 7 Characters of String

I have been trying to acquire via php the class c address of a specific $REMOTE_ADDR variable. I have a series of webpages that need to be viewed only from remote clients that are on the local lan and if a client views the specific pages from outside the lan, redirect them to another webpage.

Someone else may have a better way, but I'm inclined to go with a regexp, such as ereg("([0-9]+\.[0-9]+\.[0-9]+)\.[0-9]+", $str, $results) Shawn
