title: Laravel .env variable always returns null
body: <p>I added this variable to .env file</p>
  
  <blockquote>
    <p>STRIPE_SECRET=a12345</p>
  </blockquote>
  
  <p>I would like to dump the variable using routes/web.php</p>
  
  <pre><code>&lt;?php
  dd(env('STRIPE_SECRET'));
  </code></pre>
  
  <p>But it looks like it always returns null.</p>
  
  <p>Update : Updated .env file. I only removed DB_PASSWORD.</p>
