title: how to prevent direct access to the php files embeded in the joomla articles?
body: <p>I have joomla website. I put in the articles some php files into iframes. How to prevent direct view of those files? php/htaccess referrer is weak protection since anyone can set any referrer with web browser to cheat this. </p>
  
  <p>Articles contains only iframes, nothing more. I put those files in iframes, because sometimes i change massively the content of those php files, which is not possible with joomla articles..</p>
