                </table>
            </div>
        </div>
    </div>
</div>

in the above screenshot first 3 rows should be gold images (because of same marks).

Answer 1

You can create a temporary array containing unique reverse sorted average scores. Then, when giving medals, instead of checking for places (1st, 2nd, 3rd...), check if the score matches the 1st, 2nd or 3rd score from that temporary array.

For the screenshot you posted, the array would look like:

$scores = [92.5, 90, 87.5];

and the gold medals would be all the scores with the score of $scores[0] , the silver ones are $scores[1] and the bronzes would be $scores[2] (unless you want everyone else to get bronze).
