Get translated country name from a 2 digit country code in Symfony2/Twig?

I'm not sure if you still need... but it might help someone else. this can be done through a twig extension easily (this code is based on @tomaszsobczak's answer )

<?php    // src/Acme/DemoBundle/Twig/CountryExtension.php    namespace Acme\DemoBundle\Twig;    class CountryExtension extends \Twig_Extension {        public function getFilters()        {            return array(                new \Twig_SimpleFilter('country', array($this, 'countryFilter')),            );        }        public function countryFilter($countryCode,$locale = "en"){            $c = \Symfony\Component\Locale\Locale::getDisplayCountries($locale);            return array_key_exists($countryCode, $c)                ? $c[$countryCode]                : $countryCode;        }        public function getName()        {            return 'country_extension';        }    }

And in your services.yml files

# src/Acme/DemoBundle/Resources/config/services.ymlservices:    acme.twig.country_extension:        class: Acme\DemoBundle\Twig\CountryExtension        tags:            - { name: twig.extension }

Usage example inside a twig file:

{{ 'US'|country(app.request.locale) }}

As per @Rvanlaak's comment above, \Symfony\Component\Locale\Locale is now deprecated. I think the most concise way to do this now is:

use Symfony\Component\Intl\Intl;...$country = Intl::getRegionBundle()->getCountryName($countryCode);

Inspired by Hannoun Yassir answer, I use the Intl as in the country type field.The code of twig extension is

<?phpnamespace Tbl\SagaBundle\Twig;use Symfony\Component\Intl\Intl;class CountryExtension extends \Twig_Extension{    public function getFilters()    {        return array(            new \Twig_SimpleFilter('countryName', array($this, 'countryName')),        );    }    public function countryName($countryCode){        return Intl::getRegionBundle()->getCountryName($countryCode);    }    public function getName()    {        return 'country_extension';    }}?>

Add twig extension in services.yml

# src/Acme/DemoBundle/Resources/config/services.ymlservices:    acme.twig.acme_extension:        class: Acme\DemoBundle\Twig\CountryExtension        tags:            - { name: twig.extension }

usage in the template (the country name will be display in locale by default (see Symfony/Component/Intl/ResourceBundle/RegionBundleInterface.php)

{{ user.countryCode|countryName }}

Many thanks Yassir, this version don't use locale deprecated since version 2.3 >> http://symfony.com/components/Locale
