How can PHP be used to interact with a Windows VServer to start a specific file?

To interact with a Windows VServer to start a specific file using PHP, you can use the `exec()` function to execute a command on the server. You would need to construct a command that starts the specific file on the VServer. Make sure that the PHP script has the necessary permissions to execute commands on the server.

<?php
// Command to start a specific file on the Windows VServer
$command = 'start C:\path\to\specific\file.exe';

// Execute the command on the server
exec($command);
?>
