    $name = htmlspecialchars($_POST["name"]);
    $email = filter_var($_POST["email"], FILTER_SANITIZE_EMAIL);
    
    // Validate input data
    if (empty($name) || empty($email)) {
        echo "Please fill out all fields";
    } else {
        // Process the form data securely
        // (e.g. save to database, send email, etc.)
