Access in yaml to array element (Symfony 2)?

Question

symfony

Maybe someone came across. There is a bundle with parameters.yml
parameters.yml
-

parameters:<br>
    acme_default.options:<br>
        constants:<br>
            root_path: /home/www/acme.ru/web<br>
    acme_default.config_path: %acme_default.options.constants[root_path]%/cfg.ini<br>

This kind of thing doesn't work. Question: how can I get to the parameter (root_path) in the yml file, which lies in the array (constants)?

Answer 1

Looked at the source. Parameters must be plain-value, i.e. stupidly key-value i.e. in php you can then get an array via getParameter(), and then its element, but not in the yaml file itself. Thank you.

Answer 2

Format the code.

Answer 3

%acme_default.options.constants.root_path%/cfg.ini?
