How to access variable from another controller – CakePHP

Question:

How do I access variables from another controller ?

For example:

I have an controller X , and in the index action, I create a variable (or a constant). From controller Y , I want to access the variable (or constant) value of controller X .

Is it possible to do that? Remembering that each action of each controller , in my application, will have a variable that must be accessible from another controller .

Controller ExampleX

class ExemploXController 
    {
        $dependencias = array("index","listar");

        public function index()
            {
                echo "Index";
            }
        public function funcaoX()
            {
                echo "Funcão X";
            }
        public function listar()
            {
                echo "listando";
            }
    }

Controller ExemploY

class ExemploYController
    {
        $dependencias = array("index","atualizar");

        public function index()
            {
                //pegar o valor da variável $dependencias da controller ExemploXController
                $dependency[] = ExemploXController->dependencias;
            }
        public function funcaoY()
            {
                echo "Funcão Y";
            }
        public function atualizar()
            {
                echo "atualizar";
            }
    }

Answer:

Hello, can you create a requestAction . With it you can use it both on the same controller and on other controllers, but don't forget to create the cache element .
