Hi Rodney,
That is like asking: "Where are the rocket blueprints for the Saturn5 in
PHP?"
PHP is executed at the server, and returns a response, which can be HTML.
If you want to use DOM-specific functionality, this is executed by the
browser that receives the HTML produced by PHP.
PHP is completely out-of-touch with the HTML it delivered.
You need Javascript to access DOM in a browser.
Of course, this doesn't mean PHP cannot be used to deliver nice
Javascript/HTML/etc, but PHP is NOT in charge anymore once the HTML arrives
at some client (browser).

Erwin Moller
