Write some Software WordPress function modification

I need some one to modify a WordPress function that count and gets the post views. The function is the following: function getPostViews($postID){ $count_key = 'post_views_count'; $count = get_post_meta($postID, $count_key, true); if($count==''){ delete_post_meta($postID, $count_key); add_post_meta($postID, $count_key, '0'); return "0 View"; } return $count.' Views'; } function setPostViews($postID) { $count_key = 'post_views_count'; $count = get_post_meta($postID, $count_key, true); if($count==''){ $count = 0; delete_post_meta($postID, $count_key); add_post_meta($postID, $count_key, '0'); }else{ $count++; update_post_meta($postID, $count_key, $count); } } // Remove issues with prefetching adding extra views remove_action( 'wp_head', 'adjacent_posts_rel_link_wp_head', 10, 0); So i need this $count++; to count different for the new posts and different for the old posts. For example if post are 2 hours news then $count = $count++ + 1; else if post are 12 hours old then $count++; I want to increase the views of the new posts and for the old post after a time limit to start count normally. To avoid the big amount of post views in the new posts i need the $count++; to stop in i limit of views. For example if post are 2 hours news then $count = $count++ + 1; LIMIT=500000-Views and after the 500000 Views $count++; else if post are 12 hours old then $count++; Please be informed that i need a WordPress expert and specialist!
