CakePHP: best way to call an action of another controller with array as parameter?

Question

In a controller, what is the most appropriate way to call the action of another controller and also pass an array as parameter?

I know that you can use requestAction

Answer 1

I put into my AppController class the following method and variable so it is caches in case of multiple calls

var $controllersArray = array();

function _getController( $pControllerName ){
    if ( ! isset($this->controllersArray[$pControllerName]) ){
        $importRes = App::import('Controller', $pControllerName);// The same as require('controllers/users_controller.php');
        $strToEval = "\$controller = new ".$pControllerName."Controller;";
        $evalRes = eval($strToEval);
        if ( $evalRes === false ){
            throw new AppException("Error during eval of given getController '$pControllerName'");
        }
        $controller->constructClasses();// If we want the model associations, components, etc to be loaded
        $this->controllersArray[$pControllerName] = $controller;
    }
    $result = $this->controllersArray[$pControllerName];

    return $result;
}
