PHP Object-Oriented reCAPTCHA

The PHP reCAPTCHA library encapsulated in a class to simplify usage with frameworks that support autoloading.

Generating Captcha

$recaptcha = new Recaptcha($publicKey, $privateKey);
$recaptcha->get_html();

Validating Response

$recaptcha = new Recaptcha($publicKey, $privateKey);
$response = $recaptcha->check_answer($_SERVER['REMOTE_ADDR'], $_POST['recaptcha_challenge_field'], $_POST['recaptcha_response_field']);

if ($response->is_valid) {
	// Captcha was completed successfully
} else {
	// Captcha was not completed successfully
}
