This is add-html-to-page-with-php-include.php.
Here is the text without the include yet. Any text below this paragraph came from the php include.
Using a php include required a php extension (this file) but the included file can be html, text, or php.
Put <?php include("1bunchastuff.html"); ?> in the body section since that is where it goes.
The include below is simply the text in the 1bunchastuff.html file.
Here is the text in the 1bunchastuff.html include file. It has no head, body, or html tags. Just the html code.
