Country and Region Names
~~~~~~~~~~~~~~~~~~~~~~~~
The ``Countries`` class provides access to the name of all countries according
to the `ISO 3166-1 alpha-2`_ list of officially recognized countries and
territories::

In the world there are some territorial disputes that make it hard to define
what a country is. That's why the Intl component provides a ``Regions`` class
instead of a ``Countries`` class::

use Symfony\Component\Intl\Regions;
use Symfony\Component\Intl\Countries;

\Locale::setDefault('en');

$countries = Regions::getNames();
// ('regionCode' => 'regionName')
$countries = Countries::getNames();
// ('countryCode' => 'countryName')
// => ['AF' => 'Afghanistan', 'AX' => 'Åland Islands', ...]

$country = Regions::getName('GB');
$country = Countries::getName('GB');
// => 'United Kingdom'

All methods accept the translation locale as the last, optional parameter,
which defaults to the current default locale::

$countries = Regions::getNames('de');
$countries = Countries::getNames('de');
// => ['AF' => 'Afghanistan', 'EG' => 'Ägypten', ...]

$country = Regions::getName('GB', 'de');
$country = Countries::getName('GB', 'de');
// => 'Vereinigtes Königreich'
