conf_path()
drupal/includes/bootstrap.inc, line 110

Description

Find the appropriate configuration directory.

Try finding a matching configuration directory by stripping the website's hostname from left to right and pathname from right to left. The first configuration file found will be used, the remaining will ignored. If no configuration file is found, return a default value '$confdir/default'.

Example for a fictitious site installed at http://www.drupal.org:8080/mysite/test/ the 'settings.php' is searched in the following directories:

1. $confdir/8080.www.drupal.org.mysite.test 2. $confdir/www.drupal.org.mysite.test 3. $confdir/drupal.org.mysite.test 4. $confdir/org.mysite.test

5. $confdir/8080.www.drupal.org.mysite 6. $confdir/www.drupal.org.mysite 7. $confdir/drupal.org.mysite 8. $confdir/org.mysite

9. $confdir/8080.www.drupal.org 10. $confdir/www.drupal.org 11. $confdir/drupal.org 12. $confdir/org

13. $confdir/default

Code

function conf_path() {
  static $conf = '';

  if ($conf) {
    return $conf;
  }

  $confdir = 'sites';
  $uri = explode('/', $_SERVER['SCRIPT_NAME'] ? $_SERVER['SCRIPT_NAME'] : $_SERVER['SCRIPT_FILENAME']);
  $server = explode('.', implode('.', array_reverse(explode(':', rtrim($_SERVER['HTTP_HOST'], '.')))));
  for ($i = count($uri) - 1; $i > 0; $i--) {
    for ($j = count($server); $j > 0; $j--) {
      $dir = implode('.', array_slice($server, -$j)) . implode('.', array_slice($uri, 0, $i));
      if (file_exists("$confdir/$dir/settings.php")) {
        $conf = "$confdir/$dir";
        return $conf;
      }
    }
  }
  $conf = "$confdir/default";
  return $conf;
