What are the potential security risks associated with using PHP to interact with client-side functionalities like the clipboard?

Potential security risks associated with using PHP to interact with client-side functionalities like the clipboard include exposing sensitive data to potential malicious attacks, such as cross-site scripting (XSS) or data theft. To mitigate these risks, it is recommended to validate and sanitize user input before interacting with the clipboard functionality. 

// Sanitize user input before interacting with the clipboard
$user_input = $_POST['user_input']; // Assuming user input is received via POST method
$clean_user_input = htmlspecialchars($user_input, ENT_QUOTES, 'UTF-8'); // Sanitize user input

// Interact with clipboard functionality using the sanitized user input
