Hence what you need is: <td width="60%"><?php echo $linkurl . "<br><textarea>" . htmlspecialchars($linkurl) . "</textarea></td>\n"; ?> In the outputted HTML this will give you: <td width="60%"><a href="http://www.blah.com">Blah</a><br><textarea>&lt;a href="http://www.blah.com"&gt;Blah&lt;/a&gt;</textarea> Which should render as a link, followed by a textarea with the HTML code for that link. If you want the first link to render as code as well then you need to run it through htmlspecialchars() too.
