Current user's machine name

[asgsoft]

While looking in the PHP predefined variables i found an intersting one: $_ENV["COMPUTERNAME"]. what this does is it gives the current username of the person viewing your site. This is quite good if you are making a poll for a intranet where each user has their own username.

Have a look at this and tell me what you think.

<?php
$username = $_ENV["COMPUTERNAME"]; //set variable

echo $username; //show the value of the variable

?>

I hope somebody finds it helpful.

Actually, this displays the computer name of the computer which the server is on. Your computer name doesn't get transmitted through the headers (as far as I know).

Im finding this doesnt work on my web server but only on my localhost server so MasterB is correct.

Try this:

echo gethostbyaddr($_SERVER['REMOTE_ADDR'])."<br/>\n";

It'll give what is essentially your point of access to the internet through your ISP, but not your actual machine name. I do not believe your true host name is ever routed (unless perhaps you have a direct connection to the internet like some edu workstations...)

How exactly does this script help?
Where can we use it?

If it told a username.. it makes the person more easy to hack...
