如果折扣百分比大于零，如何显示折扣百分比？ PHP

I have php script for selling deals. Currently, there are 2 requirements for deal; 1 is deal_value (original price) and special_value (discount price). So i have variables: deal_value, special_value, deal_percentage (which i already coded to get this discount percentage). These are inserted into database already.

So how do i show discount percentage label if the deal percentage > 0%?

FYI: i have this php html hot label already, so how do i code and display this hot_label if deal percentage > 0%?

Also, i need to echo the whole div= hot_label, which there is php inside and because there is css in this class=hot_label

 <div class="hot_label">
      <p>OFF</p>
      <b><?php echo round($h->deal_percentage); ?>%</b>
 </div>

<?php
if ( $h->deal_percentage > 0) {
    echo '<div class="hot_label"><p>OFF</p><b>' . round($h->deal_percentage) . '%</b></div>';
}
?>
