title: Laravel 5 environment config arrays?
body: <p>In Laravel 4, you could set an environment based config folder structure:</p>
  
  <pre><code>/config/app.php
  /config/dev/app.php
  /config/staging/app.php
  /config/testing/app.php
  </code></pre>
  
  <p>Can you do this with Laravel 5? I understand the <code>.env</code> concept and I'm using that to define which environment I'm in. But I need to define a config value that is an array of arbitrary length, and you can't do that with <code>.env</code> files.</p>
  
  <p>An example of what I'm trying to achieve:</p>
  
  <pre><code>if (in_array($request-&gt;input('value'), config('app.valid_values')) {
    // do something
  }
  </code></pre>
  
  <p>This <code>valid_values</code> is simply an array of values. It's of arbitrary length, so you can't just set them in your <code>.env</code> file like:</p>
  
  <pre><code>VALID_VALUE1=...
  VALID_VALUE2=...
  etc.
  </code></pre>
  
  <p>AND the array needs to be different for each environment.</p>
  
  <p>This was easy to do in Laravel 4 with environment configuration folders. But how do you do this with Laravel 5?</p>
