when will you get that variable?

on building the page?

remember where and when PHP and javascript are executed:

The pagevisiter used his browser to see a page. The browser contacts the
webserver (maybe apache). that starts PHP, which builds some HTML-Data (it
may contain some javascript) which is transfered to the Browser.
Then the Browser computes the HTML and then executes the javascript.
At that moment there is no connection to the PHP which isn't working
anymore.

The only way to give Information to the PHP is on the page call: as POST-
or GET-Parameter. That means your Javascript can build/ fill a form which
is transferred on the NEXT pagecall. (or a GET-Param as addition to the
URL)
