I'll check it out really...but php.net has as example:

<?php
$address = getenv('REMOTE_ADDR');
echo "Your IP address is $address.";
?>

>> Your IP address is .
-------------------------------------------------
Using:

<?php
$address = $_SERVER['HTTP_USER_AGENT'];
echo "Your IP address is $address.";
?>
OR...
<?php
$address = $_SERVER['REMOTE_ADDR'];
echo "Your IP address is $address.";
?>

Work correctly- so are they wrong to use? Is getenv() necessary? I'm using PHP 4.2.2- just a bit confusing when your trying to learn.

Thanks-
