What are the potential pitfalls of not including line breaks in PHP-generated HTML code?

Not including line breaks in PHP-generated HTML code can make the code harder to read and maintain. It can also lead to messy and unreadable HTML output, making it difficult for developers to debug and troubleshoot issues. To solve this problem, you can use the PHP "\n" escape sequence to add line breaks in your HTML output.

<?php
echo "<div>\n";
echo "<p>This is some text.</p>\n";
echo "</div>\n";
?>
