根据wordpress中的meta_value排名POST [例如：“12个帖子中排名3”]

All posts have a post meta_value called rating. How can I show the ranking of a certain post based on this meta_value like this: Ranked 3 out of 12 post. Sorting on meta_value is no problem but then all post have to be shown, is it possible to only show the post place in this ranking on a single post?

I sort a list of post this way in the WP_Query, can this method be used to retrieve only the ranking of 1 post?

'orderby' => 'meta_value',
'meta_key' => 'rating'

Example:

Ranked <?php echo get_post_meta($post->ID, 'rating', true);?> out of 12 post.

For the current post.
