INET_ATON() and INET_NTOA() in PHP?

Question

I want to store IP addresses in my database, but I also need to use them throughout my application. I read about using INET_ATON() and INET_NTOA()

Answer 1

Here PHP alternative functions (simple copy/paste in your program) -

function inet_aton($ip)
{
    $ip = trim($ip);
    if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_IPV6)) return 0;
    return sprintf("%u", ip2long($ip));  
}


function inet_ntoa($num)
{
    $num = trim($num);
    if ($num == "0") return "0.0.0.0";
    return long2ip(-(4294967295 - ($num - 1))); 
}
