What potential pitfalls can arise when using inline PHP code within HTML elements?

Potential pitfalls that can arise when using inline PHP code within HTML elements include readability issues, mixing logic with presentation, and security vulnerabilities. To solve this, it is recommended to separate PHP logic from HTML markup by using PHP templates or frameworks like Laravel or Symfony. 

<?php
// Separate PHP logic from HTML markup using PHP templates
include 'header.php'; // Include header template
?>
<div class="content">
    <?php
    // PHP logic here
    ?>
</div>
<?php
include 'footer.php'; // Include footer template
?>
