title: CodeIgniter - Delete file, pathing issue
body: <p>I have 3 folders in my root, "application", "system", and "uploads". In application/controllers/mycontroller.php I have this line of code. </p>
  
  <pre><code>delete_files("../../uploads/$file_name");
  </code></pre>
  
  <p>The file does not get deleted and I have tried a number of pathing options like ../ and ../../../ any ideas? Thanks.</p>
