IP Address splitting

[Anon]

Hiya Guys,

Anybody know of a way of splitting up the 4 octaves of an IP address?

for example ip address 195.143.23.141

$oct1=195
$oct2=143
$oct3=23
$oct4=141

thanks!

also does anyone know how to get the windows nt machine name using php? I.e. in the NT environment variables you have %computername% which would be say "COMPUTER1"

ta!

<?

$ip = "162.11.23.1";

$arr = explode(".",$ip);

$oct1 = $arr[0];
$oct2 = $arr[1];
$oct3 = $arr[2];
$oct4 = $arr[3];

?>

To get remote_host .... I don't think this is possible, (maybe in other CGI languages ??)
But, workstation name is not part of HTTP Header ...

Thanks for your help LexZEUS !

Hi again,

Is there anyway of Zero filling the last octet. i.e. so that if $oct4 = 1, you could make it 001 ?

Thanks

ereg_replace ?

$lastoct = "9";

while(strlen($lastoct) < 3) {
$lastoct = "0" . $lastoct;
}

something like that?

A bit lazy ??

Anyway making the whole IP a string before you use explode should solve the problem

$octet = sprintf("%03d", $octet);
