title: Is there a variable which can limit usability of sessions in a folder to certain files?
body: <p>I have PHP application, created by someone else. Each section is one php file. I want to extend it by another section, but each time I create php file for the new section, that file shows an error of session_start:</p>
  <blockquote>
  <p>open(/var/lib/php5/sess_<em>somecode</em>, O_RDWR) failed: Permission denied
  (13)</p>
  <p>Failed to write session data (files). Please verify that the current
  setting of session.save_path is correct</p>
  </blockquote>
  <p>The file contains the same php code as another page/section which goes well. Link to that file is correct as well, it still links to file on <a href="http://domain.com" rel="nofollow noreferrer">http://domain.com</a> which is default setting, not <a href="http://www.domain.com" rel="nofollow noreferrer">http://www.domain.com</a>. It behaves like there is some list/array of names of files which are only allowed to store session in tmp folder. When I create new one it isn't in that list/array, so it shows this warning. Like I don't have permission to create new file and use the same session in it.</p>
  <p>Is there something like that list/array I'm looking for, or I'm searching absolutely out of the way?</p>
