Calculate IP Between IP range PHP

Question

How do i calculate between Ip Addresses. for Example:

$ip_low_range = '91.0.0.0';
$ip_max_range = '91.23.255.255';
$user_ip  = '91.1.0.0';
in_range($user_ip , $ip_low_range , $ip_max_range,);

in_range() - is the function that i'm looking for.

Thanks!

Answer 1

You could use ip2long:

$ip_low_range = ip2long('91.0.0.0');
$ip_max_range = ip2long('91.23.255.255');
$user_ip  = ip2long('91.1.0.0');
if ($user_ip >= $ip_low_range && $user_ip <= $ip_max_range) {
    echo "in range";
}
