How to access nested parameter values in Symfony2

Question

I created a parameter in my parameters file:

parameters:
    category:
        var: test

I can access this in PHP by fetching it like this:

$var = $this->container->getParameter('category');
$var = $var['var'];

But how can I access this parameter in my config.yml? For example, I want to pass this parameter to all my twig files as a global twig variable:

twig:
    globals:
        my_var: %category.var% # throws ParameterNotFoundException

_{^{(Sidequestion:

I assumed I could access it via getParamter('category.var'), but got an error there. Do you know a nicer way than my two-liner? $this->container->getParameter('category')['var'] works, but is a syntax error according to my IDE.)}}

If you're using NetBeans just change Project Properties -> Sources -> PHP Version to higher, because function array dereferencing has been added in PHP 5.4 (and yes, NetBeans is smart enough to check it and tell it's "syntax error"). — Wirone

$this->container->getParameter('category')['var']

..is actually a pretty good way to go. Which version of PHP is your IDE using for its syntax checking? Somebody please correct me, but I think this behavior was made valid in 5.3 or 5.4.

As for your second question, perhaps this will help you - stackoverflow.com/questions/6787895/…

I am using Aptana Studio 3. Thanks for your answer on the sidequestion, but I am more interested in the answer for the main question. The linked question does not help me as there are no nested parameters (but parameters with . inside...)
