Put update-like notification bubble on multiple CPTs menus for pending items

I made this work iterating through a post types list, and pinpointing the correct $menu key for the post type using a secondary function (instead of manually iterating through the $menu object).

Function reference: get_post_types and wp_count_posts.

add_action( 'admin_menu', 'pending_posts_bubble_wpse_89028', 999 );

function pending_posts_bubble_wpse_89028() 
{
    global $menu;

    // Get all post types and remove Attachments from the list
    // Add '_builtin' => false to exclude Posts and Pages
    $args = array( 'public' => true ); 
    $post_types = get_post_types( $args );
    unset( $post_types['attachment'] );

    foreach( $post_types as $pt )
    {
        // Count posts
        $cpt_count = wp_count_posts( $pt );

        if ( $cpt_count->pending ) 
        {
            // Menu link suffix, Post is different from the rest
            $suffix = ( 'post' == $pt ) ? '' : "?post_type=$pt";

            // Locate the key of 
            $key = recursive_array_search_php_91365( "edit.php$suffix", $menu );

            // Not found, just in case 
            if( !$key )
                return;

            // Modify menu item
            $menu[$key][0] .= sprintf(
                '<span class="update-plugins count-%1$s" style="background-color:white;color:black"><span class="plugin-count">%1$s</span></span>',
                $cpt_count->pending 
            );
        }
    }
}

function recursive_array_search_php_91365( $needle, $haystack ) 
{
    foreach( $haystack as $key => $value ) 
    {
        $current_key = $key;
        if( 
            $needle === $value 
            OR ( 
                is_array( $value )
                && recursive_array_search_php_91365( $needle, $value ) !== false 
            )
        ) 
        {
            return $current_key;
        }
    }
    return false;
}
