Question

i would like to know if it is possible to have a function in PHP which returns an interface or a class which contains an interface?

i tried something like this, but it fails

<?php
//class for list of controllers for ACL
class Gestionale_Action_Helper_Crud extends Zend_Controller_Action_Helper_Abstract {

     interface crud_controller
    {
        public function indexAction();
        public function modificaAction();
        public function cancellaAction();
        public function creaAction();
    }


    public function getCrudInterface(){
        return $this->crud_controller;
    }
}

what i wanted to do, in zend framework, create an interface that crud controllers must implement, or even better if i could create an abstract controller and have them implement that

thank you

Just place the interface outside of any class (preferably in a different file) and let it be implemented by all your crud-controllers.

<?php
class GrudController implements CrudInterface
{
    // ...
}
