<?
echo var_dump(ip2long('')); echo "\n";
echo var_dump(ip2long('255.255.255.255')); echo "\n";
echo var_dump(ip2long('255.255.255.255aaa')); echo "\n";
?>
int(-1)
int(-1)
bool(false)
So, if you want to validate an IP address use:
<?
function validate_ip($ip) {
$long = ip2long($ip);
return (!empty($ip) && $long !== false);
}
?>
?>
