Gets the name of the parent directory of a given path.

This method is usually accessed through \Drupal::service('file_system')->dirname(), which wraps around the normal PHP dirname() function, since it doesn't support stream wrappers.

Parameters

string $uri: An optional URI.

Return value

string The directory name, or FALSE if not applicable.

Overrides StreamWrapperInterface::dirname

Code

public function dirname($uri = NULL) {

  //   $this->_debug("dirname($uri) called.");
  if (!isset($uri)) {
    $uri = $this->uri;
  }
  $scheme = \Drupal::service('file_system')
    ->uriScheme($uri);
  $dirname = dirname(file_uri_target($uri));

  // When the dirname() call above is given '$scheme://', it returns '.'.
  // But '$scheme://.' is an invalid uri, so we return "$scheme://" instead.
  if ($dirname == '.') {
    $dirname = '';
  }
  return "{$scheme}://{$dirname}";
