I am trying to create a page that shows the user their zip code when they are on my page.
(if any of you are familiar with GeoIP data, thats what I am using. )
I have a conversion that converts the users IP address into an IP number, that conversion is:
ipnum = 16777216*w + 65536*x + 256*y + z
where w.x.y.z are the ip sections (000.000.000.000)
My question is, using
$_SERVER['REMOTE_ADDR'];
is there a way for me to section the users ip address and assign the section of the ip address to variables?
for example:
usersip = 192.168.123.5
w = 192; x = 168; y = 123; z = 5;
Thanks!
list($w, $x, $y, $z) = explode('.', $ip);
Also, instead of math you could convert your ip to int with ip2long
