What are the best practices for handling dynamic HTML generation in PHP to avoid issues with concatenation and potential errors?

When generating dynamic HTML in PHP, it's best to avoid directly concatenating HTML strings to prevent errors and improve code readability. Instead, use a templating engine like Twig or separate your HTML markup from PHP logic using heredoc syntax or output buffering.

// Using heredoc syntax to separate HTML markup from PHP logic
$html = <<<HTML
<div>
    <p>{$dynamicContent}</p>
</div>
HTML;

echo $html;
