You need to encode all html entities. Most languages already have some automatic way of escaping the code.

In Java, using JSTL in the JSP, you can do this:

<c:out value="${valorAqui}" escapeXml="true"/>

In PHP, there is the htmlentities function that you use:

<?php echo htmlentities($texto); ?>

I did not get to this, but I believe that in a simple way you could also print the php code as follows within HTML:

<?php echo '<?php //aqui você insere seu código... ?>' ?>

See:

<section class="bg-light" id="links">
  <div class="container">

    <h1 class="text-center text-info">Teste PHP</h1>

      <?php
          echo"Olá, Mundo!";
          echo("<h2>Olá, Mundo</h2>");
          ?>

    </div>
  </div>
