function conf_path

Returns the appropriate configuration directory.

Returns the configuration path based on the site's hostname, port, and pathname. See default.settings.php for examples on how the URL is converted to a directory.

Parameters

bool $require_settings: Only configuration directories with an existing settings.php file will be recognized. Defaults to TRUE. During initial installation, this is set to FALSE so that Drupal can detect a matching directory, then create a new settings.php file in it.

bool $reset: Force a full search for matching directories even if one had been found previously. Defaults to FALSE.

Return value

The path of the matching directory.
