I integrated my `ckeditor with ckfinder 3` that has the ability to store files on the `Amazon S3` cloud.

In my ckfinder `config.php` file, that is located in `public/assets/plugins/ckfinder` i have hardcoded the key, secret key, bucket and region, that are needed to make connection with the cloud. 

But i want to get the config items from the `.env` file. 

So far i tried this in ckfinder's config.php:

```
require $_SERVER['DOCUMENT_ROOT'].'/../bootstrap/autoload.php';
$app = require $_SERVER['DOCUMENT_ROOT'].'/../bootstrap/app.php';
var_dump($app->environment('S3_KEY');

```

But this fails with an error: `Fatal error: Uncaught exception 'ReflectionException' with message 'Class env does not exist' in /home/vagrant/projects/dk/vendor/laravel/framework/src/Illuminate/Container/Container.php on line 779`

So the question is, how to i access environment variables outside Laravel app ?

Thank you!
