How can HTML elements be properly nested in PHP code to ensure correct functionality?

When embedding HTML elements within PHP code, it is important to ensure proper nesting to maintain correct functionality. This means ensuring that opening and closing tags match up correctly and that elements are structured in a logical hierarchy. One way to achieve this is by using PHP's echo or print statements to output HTML code within the PHP script. 

<?php
echo "<div>";
echo "<p>Hello, world!</p>";
echo "</div>";
?>
