[Taking a step back]
I think it'd help if the OP says why they want to do all this. If I
ever have trouble doing something I usually find that I am trying to
fit a square peg in a round hole and I need to approach the problem in
a different way.
But, given what we know, it looks like the OP needs one HTML page with
some PHP at the top. Like:
HTML headers
<?php
if (isset($_REQUEST['dofunction'])) {
function();
}
?>
rest of the HTML page including:
<a href="<?php echo $_SERVER['PHP_SELF'].'?dofunction'; ?>">click
here</a>
