Code

public function dirname($uri = NULL) {
  if (!isset($uri)) {
    $uri = $this->uri;
  }
  $scheme = file_uri_scheme($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}";
}
