Some extra env providers to make using Symfony 3+ .env files not such a pain

<rant type="personal">I much prefer the old parameters.yml way of doing things as it was more flexible, but Symfony has decided to move to dotenv, so...</rant> This bundle adds in 'missing' ways to parse dotenv variables so that you can not hate it so much.

You know the score:

composer require c0ntax/env-providers-bundle

And don't forget to add the following to your Kernel if you're not using Flex:

    public function registerBundles()
    {
        $bundles = [
            // ...
            new C0ntax\EnvProvidersBundle\C0ntaxEnvProvidersBundle(),
            // ...
        ];
    }

Currently, a little configuration-light, you can add the following:

c0ntax_env_providers:
    array:
        return_null_if_empty: true # If the env variable = '' then return a null instead of an empty array

In your .env file

ENV_VAR=this,that, other

and then in your configuration

parameters:
    array_thing: '%env(array:ENV_VAR)%'

Err, that's it. array_thing now equals ['this', 'that', 'other']
