Your page's problem is entirely a Javascript problem. Has nothing to do
with PHP:
Try moving the "onchange" from the <option> tag to the enclosing
<select> tag. (It is the value of the <select> that changes when a
different <option> is selected.)
Now for the lecture:

Yes, it's impossible. PHP is executed on the server. Javascript is
executed in the browser. So Javascript cannot be called from PHP running
on the server.
PHP is a document generator. You can use it to generate Javascript the
exact same way you use it to generate HTML. But the resulting Javascript
won't be executed till it gets to the browser.
The main problems you'll have generating Javascript from PHP are:
--keeping control of all the embedded quotes.
--keeping control of the embedded logic (and remembering to remember
that the Javascript part isn't being executed just yet :)
