What is the issue with the PHP link in the forum thread?

The issue with the PHP link in the forum thread is that it is not properly formatted with the correct syntax. To solve this issue, you need to ensure that the PHP code is enclosed within the opening and closing PHP tags (<?php and ?>) and that the link is properly concatenated within the echo statement using the concatenation operator (.)

&lt;?php
echo &#039;&lt;a href=&quot;https://www.example.com&quot;&gt;Click here&lt;/a&gt;&#039;;
