title: Securing a text file in a website folder
body: <p>I have several folders in my website directory which contains textfiles called "secure.txt".
  For security reasons the URL of these files are never shown in the webbrowser but my website searches for these files (PHP code), which contains sensitive information. </p>
  
  <p>How can I make the PHP code allowed to read these files but restrain access through the url, so a potential hacker wouldn't be able to read the content of these files?</p>
