Its done exactly the same as when you put it in an HTML file. There are 2 ways you can do it:
<html>
<?php
// php stuff
?>
</html>
Or you can do it like this:
<?php
echo "<html>";
// php stuff
echo "</html>";
?>
change the extention of the .HTML file to .php and then open the file that was previously HTML and put <?php include ("path/to/second/php/file.php"); ?> so for example if i have page1.HTML and page2.php i rename page1.HTML to page1.php and then put <?php include ("page2.php"); ?> where i want page2 to appear. Note: Any HTML file can be renamed to have a .php extention even if it doesnt contain any PHP.

PHP support is not up to the clients (browsers). If it runs on the server, then HTML is served to the client. PHP may have generated the HTML, but that does not matter to the client.
PHP files are HTML files with any amount of PHP intermingled into it, so the file can be empty or only contain HTML and be valid, yes.

there are in fact two basic methods - one is called minimal PHP, and the second tends to be referred to as the CGI-way. minimal php means that you're making php secions in HTML only where really necessary (using the php section begin (<?php ) and end (?> ) tags.). the CGI-way, or maximum PHP means, that you're in fact embedding HTML into strings in php, and the whole page is echo()ed. the second way tends to be viewed as an abuse of php by some people, as php was meant to be "templating" language, and designed to be used mainly the first way.
