About actions in the YII framework

Public Function Actioncaptcha () {return Array (' class ' = ' system.web.widgets.captcha.CCaptchaAction ', ' height ' = >20, ' width ' =>20, ' maxLength ' =>4, ' minLength ' =>4);}

Public function actions () {return array (' Captcha ' =>array (' class ' = ' system.web.widgets.captcha.CCaptchaAction ') ', ' height ' =>25, ' width ' =>80, ' maxLength ' =>4, ' minLength ' =>4 ');}

I think it's all about calling the Captcha class. Why the first one can't be used, the 2nd one can use it.

Apparently because the first one's missing a layer.
The format is wrong.

One less, you have to format it.

is independent of the layer. It's about the actions, okay?

What's the matter?
The second paragraph is not a key CAPTCHA (verification code)?
And who in the first paragraph would know the attribution of the returned data?
