如何更改从动态代码生成的代码？

Question

抱歉，我不是开发人员。我只想在此页面https://tolelight.com.vn/上将<h3>SẢN PHẨM</h3>更改为<h1>SẢN PHẨM</h1>，其余<h3>标签应保持不变，应该保持不变

<h1>SẢN PHẨM</h1> <h3>CHỨNG CHỈ</h3> <h3>TIN TỨC</h3>，该怎么做？

PHP代码：

<div class="head">
<h3><?=$name?></h3>
<div class="gach"></div>
</div>

完整代码：

<section id="slider">
  <div class="wraper">
    <div id="slide" class="nivoSlider">
      <?php
        $sql=mysql_query("select * from advertise where catid=3 and block = 0 order by id desc ");
        while($r=mysql_fetch_array($sql)){
      ?>
      <img src="<?=$root?>uploads<?=$r['image']?>" data-thumb="<?=$root?>uploads<?=$r['image']?>"/>
      <?php } ?>
    </div>
  </div>
</section>
