How can PHP be used to handle user interactions when JavaScript is disabled?

When JavaScript is disabled, PHP can be used to handle user interactions by relying on server-side processing instead of client-side scripting. This can be achieved by using PHP to validate form inputs, process form submissions, and generate dynamic content without relying on JavaScript. By implementing server-side validation and processing, the application can still function properly even when JavaScript is disabled. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    // Server-side validation
    if (empty($name) || empty($email)) {
        echo "Please fill out all fields.";
    } else {
        // Process form submission
        // Insert code here to handle form data
        echo "Form submitted successfully!";
    }
}
?>
