What are the advantages of using a div container instead of an iframe for including specific content in a PHP website?

Using a div container instead of an iframe for including specific content in a PHP website offers several advantages. Div containers are more flexible and customizable, allowing for easier styling with CSS. They also improve website performance by loading content directly into the page without the need for a separate document like an iframe. Additionally, div containers are more search engine friendly as their content is part of the main page's HTML.

<div class="content">
  <?php include 'specific_content.php'; ?>
</div>
