Fatal error: Using method return value in write context

[PhantomWatson]

Using this plugin, I'm getting the following error:

Fatal error: Can't use method return value in write context in C:\cakephp\vendor\cake17\cakephp-recaptcha\src\View\Helper\RecaptchaHelper.php on line 64

That line is

if (empty($this->config('lang'))) {

and the error is corrected if that's changed to

$lang = $this->config('lang');
if (empty($lang)) {

This is due to a limitation of using empty() in versions of PHP before 5.5.

Thanks @PhantomWatson, this is fixed, let me know if something else is wrong !

No problem! Sorry I didn't have the time to whip up a fork and a pull request.

Thanks so much for your work on this plugin!
