PHP $_SERVER["LOGON_USER"] return nothing?
<p>I am trying to detect the "windows" username and domain which the user that is accessing my website is using.</p>

<p>so i am trying to use $_SERVER["LOGON_USER"]; to display windows login info but it is always returning empty. I am using PHP 6.0 and I am running this website on my local machine which is  running on Windows 7.
How can i get this variable to populate?</p>

<p>Thanks</p>
