ZF ReCaptcha Inline Configuration Code Snippet

Somehow it’s always a pain to find the right configuration parameters and proper format in ZF which makes me reverse engineer them.

$this->captcha = new Zend_Form_Element_Captcha('captcha',
	array(
		'captcha'=>array ('ReCaptcha'),
		'captchaOptions'=>array (
			'pubkey'=>'...',
			'privkey'=>'...'
		)
	)
);
