Determine whether a path is in the administrative section of the site.
By default, paths are considered to be non-administrative. If a path does not match any of the patterns in path_get_admin_paths(), or if it matches both administrative and non-administrative patterns, it is considered non-administrative.
$path: A Drupal path.
TRUE if the path is administrative, FALSE otherwise.
function path_is_admin($path) {
$path_map =& drupal_static(__FUNCTION__);
if (!isset($path_map['admin'][$path])) {
$patterns = path_get_admin_paths();
$path_map['admin'][$path] = drupal_match_path($path, $patterns['admin']);
$path_map['non_admin'][$path] = drupal_match_path($path, $patterns['non_admin']);
}
return $path_map['admin'][$path] && !$path_map['non_admin'][$path];
}
