I think what you needs is Javascript code and not PHP
with php:
As I said,
<div id="loadingNode"><?php print <content>?></div>
Where <content> will be the result of the user clicking the
link in the html. But the link has to point back to server side
php code. If you don't want the link to point back to server side php
you do need javascript. But what you want to place in the div must
already be in the page somewhere as a javascript string or
hidden input field.
You can also have the link initiate an async AJAX call to the server
to get the div contents. And again that requires calling server side
php. Php does not run in the browser. Only javascript (or in the case
of Internet Explorer: VBscript: and in all you can use Flash
ActionScript
in an SWF file). These client side scripting approaches are separate
subjects and require a good understanding of how to use them.

The way I would do this is to have some element in your html
with an anchor tag with an href value set to your page
LIke so
<?
$fileself = basename($_SERVER['PHP_SEF'])
$div = "<div marup>";
if($_GET[do] == "changediv")
{
$div = "div markup changed";
}
?>
<html>
etc
<body>
<a href="<?php print $fileself; ?>?do=changediv">Change div</a>
<?php print $div ?>
</body>
</html>
In this case the user has to click the anchor, or there
will have to be some more involved javascript processing
involved, like an ajax request sent, but it still requires an
action of the use to initiated.
