You can't run PHP like that onchange. That runs Javascript code, not PHP. If you want to use PHP to change something you will need to have Javascript use AJAX to send the request to PHP with the value of the element, PHP can do whatever it needs to do and return a result, and Javascript will need to get the result and update the page. Check the AJAX reference.
