title: Allowing only localhost to access a folder where all inclusive php files exist
body: <p>We all have php files like 'connect_db.php' for include purposes only.</p>
  
  <p>Suppose I have all those inclusive .php files in "www/html/INC"</p>
  
  <p>And I have index.php
  </p>
  
  <p>I want index.php accessible from browser to everyone, but I want to prevent users' direct access to "www/html/INC" folder. (e.g. when type in the browser 'www.domain.com/INC/' -> 404 error etc)</p>
  
  <p>How do I achieve this?</p>
  
  <p>Preferrably using .htaccess file in the root directory please.</p>
