symfony - How return an array from a symfony2 controller action? -

in symfony2 project need call same action in many controllers , action should return simple php array passed twig template these controllers. how can it?

a pratical example can explain situation better.

1.shared controller

// acme/demobundle/controller/metascontroller  class metascontroller extends controller {       public function metasaction() {            $myarray= array();           return $myaarray;        }  } 

2. page render controller

   // acme/demobundle/controller/pagecontroller  class pagecontroller extends controller {         protected $property = "test";         public function indexaction() {            $metas= $this->forward('acmedemobundle:metas:metas');            return $this->render('acmedemobundle:page:index.html.twig', array('property'=>property,    'metas'=>$metas));         }  }  

when error: controller must response array given.

you should create service

// acme/demobundle/controller/metascontroller class metascontroller {       public function metasaction() {            $myarray= array();           return $myaarray;        }  } 

declare service in acme\demobundle\resources\config\services.yml

services: demo.metas: class: "acme\demobundle\controller\metascontroller"

then can use in other controller

// acme/demobundle/controller/pagecontroller  class pagecontroller extends controller {         protected $property = "test";         public function indexaction() {            $metas= $this->get('demo.metas')->metas();            return $this->render('acmedemobundle:page:index.html.twig', array('property'=>property,    'metas'=>$metas));         }  }
