title: Can an empty index.php truly hide its folder?
body: <p>Say I have an <code>/images</code> folder in my website, which I don't want to be browsed by visitors. I usually prevent it by creating an empty <code>./images/index.php</code> file. Is it 100% safe?</p>
  
  <p>I mean, if the user knows the filename, they can type <code>website.com/images/image.jpg</code>, that's OK, but they cannot see the contents of the folder, right?</p>
