It should be easy. I assume you know how to write codes to let your reader to save their points of review to your database:
<?php
  $total_of_points = 35;
  $no_of_reviewers = 10;
  // $total_of_points and $no_of_reviewers should be received from your database
  $no_of_star = $total_of_points/$no_of_reviewers;
  $max_no_of_star = 5;
  $empty_star_image = "<img src=\"images/empty_star.gif\">";
  $star_image = "<img src=\"images/star.gif\">";
  for ($i = 0; $i < $no_of_star;$i++)
    echo $star_image;
  if ($no_of_star < $max_no_of_star)
  {
        for ($i = 1;$i <= $max_no_of_star - $no_of_star;$i++)
         echo $empty_star_image;
  }
?>
