note 119272 added to function.is-numeric

Hey everyone! I have brought a handy function which checks if the input is an IP address. I posted here because it is a numeric string, and uses function is_numeric(); <?php /* is_ipaddress($input) */ function is_ipaddress($input) { $ctra = 0; $tmpout = explode(".",$input); if (count($tmpout) == 4) { // There are four sections in the array (Ex. XXX.XXX.XXX.XXX) // Check if all elements of array are a number (Ex. 127.0.0.1) foreach ($element in $tmpout) { if (is_numeric($element)) { // The element is numeric. ++$ctra; } } // Is the count of numeric elements = 4 ? if ($ctra == 4) { return true; } else { return false; } } else { return false; } } ?> If you can condense this further, please let me know @ my email address I have posted under.
