What are the limitations of using PHP to determine the logged-in Windows user on a computer?

One limitation of using PHP to determine the logged-in Windows user on a computer is that it requires the server to be running on a Windows machine, as PHP does not have direct access to the operating system's user information. To work around this limitation, you can use a combination of PHP and a server-side scripting language like PowerShell to retrieve the logged-in user's information and pass it back to PHP for processing. 

// Execute a PowerShell command to get the logged-in user
$command = 'powershell.exe "Get-WmiObject -Class Win32_ComputerSystem | Select-Object -ExpandProperty UserName"';
$user = exec($command);

// Extract the username from the output
$user = explode('\\', $user)[1];

// Output the logged-in user
echo 'Logged-in user: ' . $user;
