im from australia too :)
more information on server variables is available from
http://www.php.net/manual/en/reserved.variables.php#reserved.variables.server
heres and example of usage, and it only allows those 3 computer to view the
page (this authentication isnt very good, as all someone would have to do is
change their computers name to view the page)
(the getIP function was taken from a users comment in the PHP manual, very
handy, thanks! (to fund it search the manual for getIP)
\n";
echo "Your host name is: " . $_SERVER['HTTP_HOST'];
echo "Your browser is:" . $_SERVER['HTTP_USER_AGENT'];
echo "Your IP(s) Are: " . getIP();
function GetIP()
{
if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP"),
"unknown"))
$ip = getenv("HTTP_CLIENT_IP");
else if (getenv("HTTP_X_FORWARDED_FOR") &&
strcasecmp(getenv("HTTP_X_FORWARDED_FOR"), "unknown"))
$ip = getenv("HTTP_X_FORWARDED_FOR");
else if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR"),
"unknown"))
$ip = getenv("REMOTE_ADDR");
else if (isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR']
&& strcasecmp($_SERVER['REMOTE_ADDR'], "unknown"))
$ip = $_SERVER['REMOTE_ADDR'];
else
$ip = "unknown";
return($ip);

Some type of unique host Id is needed by the PHP scripts to contruct
database records. For this exercise, we are not using PHP sessions, and the
students do not have usernames and passwords for access to the database.
Access is automatic after each host is logged onto the intranet.
