Argument 2 passed to ReCaptcha\ReCaptcha::__construct() must be an instance of ReCaptcha\RequestMethod, instance of ReCaptcha\RequestMethod\Curl given

[unrivaledcreations]

I encountered this interesting error with recaptcha while developing for Silex (Symfony2). The error reads:

Catchable fatal error: Argument 2 passed to ReCaptcha\ReCaptcha::__construct() must be an instance of ReCaptcha\RequestMethod, instance of ReCaptcha\RequestMethod\Curl given

The error is caused by:
$recaptcha = new \ReCaptcha\ReCaptcha( CAPTCHA_SECRET_KEY, new \ReCaptcha\RequestMethod\Curl() );

The fix is to modify the class definition, google/recaptcha/src/ReCaptcha/RequestMethod/Curl.php:
Original:

class Curl
{...}

Fixed:

class Curl extends Post
{...}

It appears that it must either "implements RequestMethod" or "extend" something that does.

The Curl class is a wrapper for the curl_* functions, the actual request method is the CurlPost class. However, this is not particularly readable as shown by the confusion it's caused. I'll probably move these down into a lower namespace to make it clear it's a supporting class.

Closing super old issues. Please re-raise if still relevant.
