This is a modified version of the valid_ipv4 function that will test for a valid ip address with
wild cards.
ie 192.168.0.*
or even 192.168.*.1
function valid_ipv4($ip_addr)
{
$num="(\*|[0-9]{1,3}|^1?\d\d$|2[0-4]\d|25[0-5])";
if(preg_match("/$num\.$num\.$num\.$num/",$ip_addr,$matches))
{
print_r ($matches);
return $matches[0];
} else {
return false;
}
}
