$tagsarray = array();
foreach ($tags as $tag) {
$tagsarray[] = $tag->term_id;
}
$tagslist = implode(',', $tagsarray);
// Do the query
$q = "SELECT p.*, count(tr.object_id) as count
FROM $wpdb->term_taxonomy AS tt, $wpdb->term_relationships AS tr, $wpdb->posts AS p WHERE
tt.taxonomy ='post_tag' AND
tt.term_taxonomy_id = tr.term_taxonomy_id AND
tr.object_id = p.ID AND
tt.term_id IN ($tagslist) AND
p.ID != $post->ID AND
p.post_status = 'publish' AND
p.post_date_gmt < NOW()
GROUP BY tr.object_id
ORDER BY count DESC, p.post_date_gmt DESC
LIMIT $limit;";
