How can PHP interpret HTML comment lines in non-PHP code areas, and what are the implications?

PHP can interpret HTML comment lines in non-PHP code areas by using the `echo` function to output the HTML comments. This allows PHP to handle the comments as regular text within the PHP code. By using `echo` to output HTML comments, PHP can maintain the comments in non-PHP code areas without causing any syntax errors. 

<?php
// PHP code here

echo '<!-- HTML comment -->';

// More PHP code here
?>
