  7. if (isset($_config))
  8. {
  9. return $_config[0];
  10. }
  12. // Is the config file in the environment folder?
  13. if ( ! defined('ENVIRONMENT') OR ! file_exists($file_path = APPPATH.'config/'.ENVIRONMENT.'/config.php'))
  14. {
  15. $file_path = APPPATH.'config/config.php';
  16. }
  18. // Fetch the config file
