title: Laravel - .env vs database.php
body: <p>I am confused by Laravels .env file VS other settings</p>
  
  <p>I have a .env file which has my sql database settings inside, but I also have a file in config/database.php that has these settings inside.</p>
  
  <p>When I deploy my application to an Elastic Beanstalk instance, which of these files is it using for the database settings?</p>
