PHP NestedArray::filter方法代碼示例

 /**
  * Discovers all available tests in all extensions.
  *
  * @param string $extension
  *   (optional) The name of an extension to limit discovery to; e.g., 'node'.
  * @param string[] $types
  *   An array of included test types.
  *
  * @return array
  *   An array of tests keyed by the the group name.
  * @code
  *     $groups['block'] => array(
  *       'Drupal\block\Tests\BlockTest' => array(
  *         'name' => 'Drupal\block\Tests\BlockTest',

  *         'group' => 'block',
  *       ),
  *     );
  * @endcode
  *
  * @todo Remove singular grouping; retain list of groups in 'group' key.
  * @see https://www.drupal.org/node/2296615
