No.

PHP is intended to be used with HTML outside <?php ... ?> and
in 99.9% of PHP files it is HTML that is outside <?php ... ?>.

But from a technical perspective then PHP treats what is outside
<?php ... ?> as literal text.

No parsing. Does not care what it is.

And note that even though HTML is sort of the default, then
PHP can instruct the web server that the content is something else.

<h1>xxxxxx</h1>
<?php
echo "yyyyyy\r\n";
?>

vs:

<?php
header("Content-Type: text/plain");
?>
<h1>xxxxxx</h1>
<?php
echo "yyyyyy\r\n";
?>
