what is the name of the html file you want to include? you will replace the "page" with the name of your html file, exp
your file is news.html
you will save it as:
news.php
you can also do this
<?php
$content = file_get_contents('file.html');
// then put it were u want...
print $content
?>
but go with the first option i gave you, it's easier
