Drupal : Count a view result

In a view
<?php print count(views_get_current_view()->result); ?>

Not in a view
<?php 
  $view = views_get_view('MY_VIEW_NAME');
  $view->set_display('MY_DISPLAY'); // like 'block_1'    
  $view->render();   
  print sizeof($view->result);
 ?>

Or

$view = views_get_view_result('MY_VIEW_NAME', 'DISPLAY_ID(OPTIONAL)');
$view_count = count($view);
