Why is it important to properly structure HTML elements when generating them dynamically with PHP?

Properly structuring HTML elements when generating them dynamically with PHP is important for maintaining clean and readable code, ensuring proper rendering across different browsers and devices, and improving accessibility for users with disabilities. By following best practices for HTML structure, such as using semantic tags and organizing content logically, you can create a more maintainable and user-friendly website.

<?php
// Example of generating a list of items with proper HTML structure
$items = ['Item 1', 'Item 2', 'Item 3'];

echo '<ul>';
foreach ($items as $item) {
    echo '<li>' . $item . '</li>';
}
echo '</ul>';
?>
