在基本控制器中使用phalcon类,而不是在单个控制器上使用

I have a base controller as follows

<?php
use Phalcon\Mvc\Controller;

class ControllerBase extends Controller {


    public function initialize() {

    }

    // wrapper function for debug purposes.
    public function pr($data = null) {
        echo '<pre>';
        print_r($data);
        echo '</pre>';      
    }

}

and a users controller as follows

<?php
use Phalcon\Mvc\Model\Criteria;
use Phalcon\Paginator\Adapter\Model as Paginator;
use Phalcon\Mvc\View;

class UsersController extends ControllerBase {


    public function initialize() {
        // initialize parent, here ControllerBase.
        parent::initialize();
    }

    public function loginAction() {

        // disable the main layout.
        $this->view->disableLevel(View::LEVEL_MAIN_LAYOUT);
        // disable the controller layout.
        $this->view->disableLevel(View::LEVEL_LAYOUT);
    }
        .
        .
        .
        .
        other functions...


}

i was wondering if i could call all the required phalcon classes in base controller and extend then to all the child classes so that i dont need to call them individually on each controller.

in otherwords, can i add the below code

use Phalcon\Mvc\Model\Criteria;
use Phalcon\Paginator\Adapter\Model as Paginator;
use Phalcon\Mvc\View;

only in the base controller and acces them in other controllers. I tried putting them base controller but it gave error : Class not found.

Is this the right way or is there something wrong in my approach...please help.

    If I understand your question correctly the answer is NO.

    Namespaces are language feature and works this way. The use Phalcon\Mvc\Model\Criteria only declares that you'll use Criteria class from Phalcon\Mvc\Model\ namespace. So in your code you can write new Criteria() to create object instead of using its' full name new \Phalcon\Mvc\Model\Criteria().

    You must declare each class in every file which instantiates object of that class so autoloader will know in which file given class exists.
