This is a minimalist wrapper with which you can easily integrate reCAPTCHA into your application based on Phalcon Framework.

1. Get the Recaptcha.php class and put it wherever you want. For example it can be /app/lib folder of your application.
2. Connect this class to your application. Write up a path to directory (or namespace) where this class is located.

Call get method of Recaptcha class. This method is static, so you can call it without class instantiation, like this: php Recaptcha::get($yourPublicKey)

By the same way as above. You can just call check method with a set of parameters, like this:

$answer = Recaptcha::check(
    $yourPrivateKey,
    $_SERVER['REMOTE_ADDR'],
    $this->request->getPost('recaptcha_challenge_field'),
    $this->request->getPost('recaptcha_response_field')
);
if ($answer) {
  // Captcha is correct
} else {
  // Captcha is incorrect
}
