Help w/ IP Check then Include

[Anon]

First I am very much the newbie with php and coding.

I am trying to create a script that will check the users IP then check if the user is Internal (10.x.x.x) or is External. The page will then load the correct menu.

Here is what I am using:
<?
$ip = GetHostByName($REMOTE_ADDR);
if ($ip < 10.255) include("internal_menu.php");
else include("external_menu.php");
?>

I believe that works. Is there a better way of doing this? When ever I used a longer IP address like the following:
($ip = 10.1.1.0)
I would get an error message. Any ideas on how to include a full IP address?

Thank you!

$ip=getenv("REMOTE_ADDR");

Thank you Bastien!

I am now using the following:

<?

$ip=getenv("REMOTE_ADDR");
if ($ip == 10.21) include("sample.php");
else if ($ip < 10.255) include("sample2.php");
else include("sample3.php");

?>

I am still having the problem that when I try to use a
longer IP address (10.21.0.40) to match to I get an
error.

Is there a way to enter a longer IP match?

Thanks again!
