<div class="progress">
  <div class="progress-bar" role="progressbar" aria-valuenow="<?php echo $players['players']; ?>" aria-valuemin="0" aria-valuemax="100" style="width: <?php echo $players['players']; ?>%;">
    <span class="sr-only"><?php echo $players['players']; ?> current players</span>
  </div>
</div>

If you get the max players too, set aria-valuemax=MAX PLAYERS

This won't update live though, it'll only show the up to date when you reload the page.
