is it possible to use theVariable in PHP codes ? How?

Answer 1

To use a variable that is in JavaScript in PHP, you have to send an Ajax request to a PHP page passing that variable in. This probably isn't the effect you're looking for.

JavaScript executes on the viewer's computer. PHP executes on the server. To send a JavaScript variable to PHP, you need to send some packet of information from the client to the server. This is done as a GET/POST request.
