What are the potential drawbacks of using echo to output HTML content in PHP files?

Using echo to output HTML content in PHP files can make the code harder to read and maintain, especially for larger blocks of HTML. It can also lead to mixing logic and presentation, which goes against the principles of separation of concerns. To solve this issue, it's recommended to use a templating engine like Twig or separate the HTML content into separate files. 

<?php
// Example of using a separate HTML file
include 'header.php'; // Include header HTML content
?>
<div>
    <p>This is some content</p>
</div>
<?php
include 'footer.php'; // Include footer HTML content
?>
