currency_name
New in version 2.12: The currency_name filter was added in Twig 2.12.
The currency_name filter returns the currency name given its three-letter code:
{# Euro #}
{{ 'EUR'|currency_name }}
{# Japanese Yen #}
{{ 'JPY'|currency_name }}
By default, the filter uses the current locale. You can pass it explicitly:
{# yen japonais #}
{{ 'JPY'|currency_name('fr_FR') }}
Note
The currency_name filter is part of the IntlExtension which is not installed by default. Install it first:
$ composer require twig/intl-extra
Then, use the twig/extra-bundle on Symfony projects or add the extension explicitly on the Twig environment:
use Twig\Extra\Intl\IntlExtension;
$twig = new \Twig\Environment(...);
$twig->addExtension(new IntlExtension());
