PHP executes on the server, so you have to send the form to the server.
The easiest way I know of to do this is to add
onChange="document.<formname>.submit();"
to the <select> tag (obviously, change <formname> to the name of the
form in question.
When the form reloads, use the selected item in the first combo box to
select the items to fill the second combo box.
