How can PHP developers ensure a seamless user experience for both JavaScript-enabled and JavaScript-disabled users in registration processes?

To ensure a seamless user experience for both JavaScript-enabled and JavaScript-disabled users in registration processes, PHP developers can implement server-side validation in addition to client-side validation. This way, even if JavaScript is disabled, the form data will still be validated on the server side before processing. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Server-side validation
    $username = $_POST['username'];
    $email = $_POST['email'];
    
    if (empty($username) || empty($email)) {
        echo "Please fill in all fields";
    } else {
        // Process registration
    }
}
?>
