Pass variable within controller

Question

I would like to pass a variable from one controller function to an other. In other words, how can I access the variable from an other function, within the same controller?

Thanks

As Pascal mentioned, one way is to set a property on the object:

class CategoriesController extends AppController
{

  public $foo = '';  

  public function index()
  {
    $this->foo = 'bar';
  }

  public function view($id = null)
  {
    $baz = $this->foo;

    $this->set('baz', $baz);
  }

}

Or pass it as argument:

class CategoriesController extends AppController
{

  public function index()
  {
    $foo = "bar";
    $this->view($foo)
  }

  public function view($param)
  {
    $this->set('bar', $param);
  }

}
