the table ratesummary was created using mysql create view to join the tbl_product with tbl_rating

Please try to change your returns, like these lines
<div class="rating_value"><?php echo ((#$get_rating) ? #$get_rating : '0')?> /5</div>
<div class="user_message"><?php echo $rows_num?> times rated</div>
should look something like this:
echo "<div class='rating_value'>". ((#$get_rating) ? #$get_rating : '0')/5 ."</div>".
"<div class='user_message'>". $rows_num . "times rated</div>";
