What are the potential pitfalls of using double quotation marks within PHP echo statements for HTML attributes?

Using double quotation marks within PHP echo statements for HTML attributes can lead to syntax errors or unexpected behavior if not properly escaped or handled. To avoid these pitfalls, it is recommended to use single quotation marks for HTML attributes within PHP echo statements to prevent conflicts with the double quotation marks used for the echo statement itself.

<?php
echo '<a href="https://example.com">Link</a>';
?>
