Answer 1

JavaScript is strictly client-side. You'll need to use a postback of some sort - AJAX being the weapon of choice for this. From there, store it in whatever session you're using for the user and voila, job done.

Answer 2

Use AJAX to send the coordinates to a PHP handler function so you can store them anywhere you want (DB, session etc.) and make the handler send the values to your function.

I'm suggesting a handler function as that is my style of doing things, but you can send the data to your function directly.

Also, you can opt for a time triggered event, like let's say send the data every 5 seconds or user event, the sky's the limit from there.
