You can also use explode for an IP adress to check it for validation.
<?
$ipaddr = "some ip adress";
$ipslize = explode(".", $ipaddr);
for ($i = 0; $i <= 3; $i++)
{
if (!is_numeric($ipslize[$i]))
$err = 1;
}
if (strlen($ipaddr) >= 15 && !$err)
{
echo "Valid IP adress";
}
else
{
echo "Non valid IP adres";
}
?>
