title: Change Laravel config settings from the front end?
body: <p>I'm using Laravel 5.0. I need to be able to change the value of the session lifetime in  <code>config/session.php</code> from the front end, making the value configurable to an admin user of my site. </p>
  
  <p>In the docs I've read that you can get/set variables using the config helper function, like so:</p>
  
  <pre><code>    config(['session.lifetime' =&gt; '60']);
  
      config('session.lifetime'); // '60'
  </code></pre>
  
  <p>But it it only changes the configuration value for that request. How do I persist this configuration, making it work across all requests?</p>
