#YourBundleExtension.php

namespace YourBundle\DependencyInjection;

use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Loader\YamlFileLoader;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\Config\FileLocator;

class YourBundleExtension extends Extension
{

    public function load(array $configs, ContainerBuilder $container)
    {
        $loader = new YamlFileLoader($container, new FileLocator(__DIR__ . '/../Resources/config'));
        $loader->load('services.yml');
        $loader->load('config.yml');
    }

    public function getAlias()
    {
        return 'your_bundle';
    }
}

#config.yml

parameters:
  my_bundle_config:
    data:
      DataOne: dummy
      foo: bar
    multilevel:
        data:
            inside:
                here: done!

#services.yml

services:
  config:
    class:                                YourBundle\Templating\Helper\ConfigHelper
    arguments:
      config:                             '%my_bundle_config%'
    tags:
      - { name: templating.helper, alias: config }

and now you can inject the 'config' service into all of your services, or call it from view

$view['config']->get('data.foo'); // => 'bar'
$view['config']->get('multilevel.data.inside.here'); // => 'done!'
$view['config']->get('data')->toArray(); // => array('DataOne' => 'dummy', 'foo' => 'bar')
$view['config']->get('multilevel.data')->get('inside')->get('here'); // => 'done!'

$multilevelData = $view['config']->get('multilevel.data');
$multilevelData->get('inside.here'); // => 'done!'

$view['config']['multilevel.data.inside']['here'] // =>  'done!'
