How can the concatenation of HTML tags within PHP code impact the display of data on a webpage?

When concatenating HTML tags within PHP code, it is important to ensure that the syntax is correct and that the tags are properly nested. Failure to do so can result in the display of data on a webpage being distorted or not appearing as intended. To solve this issue, it is recommended to use PHP's heredoc syntax or separate the HTML markup from the PHP code for better readability and maintainability.

<?php
// Using heredoc syntax to concatenate HTML tags
echo <<<HTML
<div>
    <h1>Title</h1>
    <p>Content goes here</p>
</div>
HTML;
?>
