In what scenarios is it recommended to handle form data processing in PHP rather than using JavaScript?

When dealing with sensitive data or data that needs to be securely processed, it is recommended to handle form data processing in PHP rather than using JavaScript. This is because PHP runs on the server-side, which means the data processing logic is not exposed to the client-side like JavaScript, making it more secure. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data securely in PHP
    $username = htmlspecialchars($_POST['username']);
    $password = password_hash($_POST['password'], PASSWORD_DEFAULT);
    
    // Save data to database or perform other operations
}
?>
