You *can* have a JavaScript handler invoke PHP -- but it requires accessing
a URL and waiting for the web-server to respond, so your response time will
not be so hot.
I'm afraid I don't recall how, but it has been posted here before...

Subject: [PHP] Invoke PHP script from onLoad handler?
> Sorry if this has come up before.
>
> I want to update a select list from a mySql database whenever the
> browser window gets the focus. This is because I anticipate that the
> user will frequently use a second window to make additions to the
> database that holds the list values while filling in the form, and I
> want those additions to be in the select list when the user returns.
>
> At present I have PHP querying the db before I output the body tag, and
> an onLoad() handler passes the returned records to a Javascript which
> populates the list box with the query results, but I have only figured
> out how to query the db when the page initially loads. I really need to
> query the db and invoke the Javascript every time the window gets focus.
>
> So, I guess my question is twofold: can I invoke a php function with an
> onLoad handler, and if so, how can I have onLoad do both things - run
> the php function to query the database, then run the Javascript to
> populate the list box? Or is there another way?
