Redirecting IP if it's between a certain IP Range

[Woottnedo]

I'm using a redirect if the user's ip is between a certain IP range. However, I'm using multiple ip ranges, so I'm wondering the best way to do this. I'm current using this to redirect, \[code\]);// read user ip adress:$ip = isset($_SERVER['REMOTE_ADDR']) ? trim($_SERVER['REMOTE_ADDR']) : '';if (($i = array_search($ip, $deny_ips)) !== FALSE){ // user is blocked header("location: http://urlhere.com/include");}\[/code\]?>But if the IP ranges are say from 72.122.166.0-72.122.159.266 and 68.61.156.0-68.61.181.255 and 78.121.74.0-78.121.77.255 then how would I do that? Thanks!
