How to configure symfony2 to use custom translation file names convention?

Question

According to official documentation :

The filename of the translation files is also important: each message file must be named according to the following path: domain.locale.loader:

I must to name all files such as messages.en_US.php , navigation.en_US.php , admin.en_US.php etc. and place in some folder.

i18n\
   admin.en.php
   messages.en.php
   navigation.en.php
   admin.fr.php
   messages.fr.php
   navigation.fr.php

But my project structure should follow the following structure:

i18n\
   en_US\
      admin.php
      messages.php
      navigation.php
   fr_FR\
      admin.php
      messages.php
      navigation.php

So how to configure symfony2 to support my structure and use translations in common way:

echo $this->get('translator')->trans('hello', array(), 'messages');

Answer 1

This is not possible. If you want to use Symfony, stick to the conventions from Symfony!

To be correct: It's not possible in a simple way. You would need to write your own translator component and throw the translator component from Symfony away..

Answer 2

It is possible, you have to load resources calling the addResource() method.

$translator->addLoader('php', new PhpFileLoader());
//Inside a loop:
$translator->addResource('php', 'path/to/messages.php', $locale);

Here is the documentation https://symfony.com/doc/4.1/components/translation.html#loading-message-catalogs
