What are the limitations of using PHP for controlling keyboard inputs?

Limitations of using PHP for controlling keyboard inputs include the fact that PHP is a server-side language and does not have direct access to client-side events like keyboard inputs. To overcome this limitation, you can use JavaScript to capture keyboard events on the client-side and send them to the server for processing. 

// PHP code to handle keyboard inputs sent from client-side using JavaScript

// Check if keyboard input data is sent via POST request
if(isset($_POST['keyboard_input'])){
    $keyboard_input = $_POST['keyboard_input'];

    // Process the keyboard input data
    // Add your logic here
}
