如何在PHP中对数据库创建的图表中的项目进行排序？

I have created a database which contains people from a run with the amount of rounds which they ran. After that I created this script which creates a html chart.

The script:

<?php
  $db = new PDO("mysql:host=HIDDEN;dbname=HIDDEN", 'HIDDEN', 'HIDDEN') or die ("Verbindung nicht möglich");
  $query_temp = $db->prepare("SELECT * FROM runners");
  $query_temp->bindParam(':id', $id);
  $id = 1;
  $query_temp->execute();

  echo '<table class="table table-hover">';
  echo '<tr>';
  echo '<th>ID</th>';
  echo '<th>Name</th>';
  echo '<th>Runden</th>';
  echo '</tr>';
  while($id_table = $query_temp->fetch(PDO::FETCH_ASSOC)) {
    echo '<tr>';
    echo '<td>'.$id_table['runner_id'].'</td>';
    echo '<td>'.$id_table['runner_name'].'</td>';
    echo '<td>'.$id_table['runner_rounds'].'</td>';
    echo '</tr>';
  }
  echo '</table>';
?>

The Database: http://img.prntscr.com/img?url=http://i.imgur.com/WklMcTG.png

Now I want to give the users the ability to sort the people for their amount of rounds which they ran. Like the most person is at the first place. How can I do this?
