New Comment:
Can be done with a oneliner:
(something along the lines of:)
if (preg_match("/^[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\$/",
$ip) {
/* It is an IP */
}
Not really worth the trouble to implement it as a PHP code feature.

function is_ip($str) // Returns True if the given string is a IP
address
{
if ((substr_count($str, ".") != 3) or (empty($str))) { return false; }
$ip_array = explode(".", $str);
for ($i = 0; $i < count($ip_array); $i++)
{
if ((strlen($ip_array[$i]) != 3) or (!is_numeric($ip_array[$i])))
{
return false;
}
}
return true;
}
I think that this function could be useful for many PHP coders :)
