Matching an IP to a CIDR mask in PHP 5?

Question

I\'m looking for quick/simple method for matching a given IP4 dotted quad IP to a CIDR notation mask.

I have a bunch of IPs I need to see if they match a range of IP

You also can use Net_IPv4 PEAR library.

function cidr_match($ip, $net){
  include_once("Net/IPv4.php");
  $objIP = new Net_IPv4();
  return $objIP->ipInNetwork($ip, $net);
}
