What is the best practice for retrieving the Windows username in a PHP application running on an IIS server?

When running a PHP application on an IIS server, the best practice for retrieving the Windows username is to use the `$_SERVER['LOGON_USER']` variable. This variable contains the username of the currently logged in Windows user. By accessing this variable, you can securely retrieve the Windows username for authentication or logging purposes. 

// Retrieve the Windows username from the $_SERVER variable
$windowsUsername = $_SERVER['LOGON_USER'];

// Output the Windows username
echo "Windows Username: " . $windowsUsername;
