What considerations should be made when designing a web application that interacts with local hardware or system functions, such as shutting down a PC, using PHP?

When designing a web application that interacts with local hardware or system functions, such as shutting down a PC, it is important to consider security implications and user permissions. You should implement proper authentication and authorization mechanisms to ensure that only authorized users can perform such actions. Additionally, error handling and logging should be implemented to handle any unexpected issues that may arise during the interaction with local hardware. 

<?php
// Check if the user is authorized to shut down the PC
if($user->isAdmin()) {
    // Execute the system command to shut down the PC
    exec('shutdown -s -t 0');
    echo "PC is shutting down...";
} else {
    echo "You are not authorized to shut down the PC.";
}
?>
