PHP is entirely server-based.  So when you load this page into your 
browser, all of the PHP is being parsed BEFORE it ever loads into the 
browser.  So the function will be executed even before the page loads.

Do it in JavaScript if you want it to be done in the browser.  What you 
have written down will show up in the source code of your browser as:

<INPUT TYPE="BUTTON" NAME="HH" value="Mul" onClick="1">

(or something like that).

PHP runs entirely on the 
server.  Server!  Server!  Server!  Server!  Honest, I promise that it 
doesn't get interpreted by the browser.  If you have any doubts, try 
writing a PHP script, reading it in your browser, and then viewing the 
source code to see what gets rendered.

For browser-side scripting, I suggest you pick up a book on JavaScript 
programming.  Nothing you do in PHP will ever be interpreted by a browser.
