Challenge 1 / 1

Suppose we open up config/packages/twig.yaml and add a global variable:

twig:
    default_path: '%kernel.project_dir%/templates'

    globals:
        the_answer: 42

How could we read a list of all of the "globals" from inside our app?

From inside of Twig:

{% for name, value in config('globals')  %}

{% endfor %}

From inside of a controller method:

$this->getConfig('twig', 'globals');

From inside of other config files:

some_other_config_key: '%twig.globals%'

You cannot read this config value from inside of your app.
