} catch(PDOException $e) {
  echo "Connection failed: " . $e->getMessage();
  exit;
}

$name = $_POST['name'];
$email = $_POST['email'];
$password = $_POST['password'];

// hash the password using bcrypt
$hashedPassword = password_hash($password, PASSWORD_BCRYPT);

// insert the user data into the database
$stmt = $pdo->prepare("INSERT INTO users (name, email, password) VALUES (:name, :email, :password)");
$stmt->execute(['name' => $name, 'email' => $email, 'password' => $hashedPassword]);

if ($stmt->rowCount() > 0) {
