调用其他controller里的变量和方法

Add this line to /config/main.php (or whatever config file you are using)

'import'=>array(
                'application.models.*',
                'application.controllers.*', <-- add this line
        'application.components.*',
...

example I used in siteController

        public function hello()
        {       
        return 'Hello World';
        }

proof that another controller can access the method

In another controller

        public function actionIndex()
        {
   echo  SiteController::hello();
        die;
...

用以上方法无法获取到controller里面的方法，

把controller里的方法前加上static设为静态就可以了
