Looking at you;re planning to do with your database query, you also need to be very careful around SQL injection - http://www.w3schools.com/sql/sql_injection.asp — athms, Mar 03 '14 at 12:09

You can't move JavaScript variables to PHP unless you refresh the page because while JavaScript is client-side, PHP is server-side. When the page is loaded, PHP's job is done.

You should have a look on how to use ajax.

Moreover, for security of your apps, always check the data which are coming from client-side.

You are looking for AJAX. You will have to send a AJAX request to your phpscript.

The easiest way to send an AJAX request is using the jQuery library.

$.ajax({
  type: "POST",
  url: "insert.php",
  data: { name: x }
})
  .done(function( msg ) {
    alert( "Data Saved: " + msg );
  });
