What I think you are trying to do is impossible, PHP can not be executed from javascript because they happen at different stages. Here is a simplified breakdown of a web request

Browser makes request to page -> Server gets request and information and processes page (PHP, ect...) -> Page outputs HTML back to browser -> Browser processes client side stuff (HTML, Javascript, flash, ect).

The PHP is done running and has already sent its output by the time the first line of javascript runs.

The only way to get a similar outcome is to use ajax.
