YII framework CCaptchaAction 解决YII验证码不更新的刷新问题

YII的验证码想要动态刷新，不是很方便，正好自己用各种找办法，终于解决了,可还是特别麻烦终于找到简单有效的办法了

不多说直接码代码，大家一看就明白，希望能帮到遇到同样问题的道友

public function actionTestCaptcha()
{


$captcha= new CCaptchaAction($this,'captcha');
Yii::app()->session['captcha'] = $captcha->fixedVerifyCode = substr(md5(time()), 11, 4);
$captcha->transparent = true;
$captcha->maxLength = 4;
$captcha->minLength = 4;
$captcha->height = 35;
$captcha->width = 80;
$captcha->run();

}
