logically no because var X doesn't exist till the page is rendered and thus it is no use to php that has already died upon rendering the  output. 

 

Now php variable $x can be used for a javaScript variable var x

 

The only real way is AJAX.

 

When the form is submitted the form inputs are placed in the $_POST array
