What are some potential pitfalls when converting HTML to RTF using PHP?

One potential pitfall when converting HTML to RTF using PHP is that not all HTML tags and attributes have direct equivalents in RTF, leading to loss of formatting or incorrect rendering. To address this, you can use a library like HTML Purifier to sanitize the HTML input and ensure that only supported tags and attributes are included in the RTF output.

// Example code using HTML Purifier to sanitize HTML input before converting to RTF
require_once 'path/to/HTMLPurifier.auto.php';

$config = HTMLPurifier_Config::createDefault();
$purifier = new HTMLPurifier($config);

$html = '<p>This is <b>bold</b> text with <a href="#">a link</a>.</p>';
$cleanHtml = $purifier->purify($html);
