Email.config.php and similar files

Good evening NC community !

I just read the Configuration Parameters of the documentation, and I wonder how following works : “You can add arbitrary files ending with .config.php in the config/ directory, for example you could place your email server configuration in email.config.php.

Indeed, I tried to create a “config/test.config.php” file in order to add something like ‘default_phone_region’ => ‘GB’, but the server can not load the file (the owner of the file being the same as for config/config.php, that is www-data:www-data in my case). How should this file look like ? Do I have to make it begin with “<php”, “$config”, and so on ?

Thanks in advance,

Yes, aditional files must be like this:

$CONFIG = array (
  'default_phone_region' => 'GB',
