php snippet to include a page into a page/node in 5.x

This snippet works great for 4.7.x

$q = $_GET['q'];
$_GET['q'] = drupal_get_normal_path('television/concepts');
print menu_execute_active_handler();
$_GET['q'] = $q;

but is not compatible for 5.0.x

Any phpsnippet to include a page into a page/node in 5.x.

Thanks!
