How can PHP be used to interact with local system processes, such as shutting down a PC, in a secure and controlled manner?

Interacting with local system processes, such as shutting down a PC, can be risky as it involves potentially dangerous actions. To do this securely and in a controlled manner, it is recommended to use PHP in conjunction with a server-side script that handles the interaction with the system processes. This way, the PHP script can send commands to the server-side script, which can then execute the desired actions with proper permissions and security measures in place. 

```php
// Example PHP code to interact with local system processes securely

// Send a shutdown command to a server-side script
$command = 'shutdown -h now';
$server_url = 'http://example.com/shutdown.php';
$response = file_get_contents($server_url . '?command=' . urlencode($command));

// Output the response from the server-side script
echo $response;
```

In this example, the PHP script sends a shutdown command to a server-side script located at `http://example.com/shutdown.php`. The server-side script would then handle the execution of the shutdown command in a secure and controlled manner.
