You can pass value from js to PHP using ajax request or add js value to URL and then reload page.

Variant #1 (using ajax):

JS side (jquery)

var js_var = 'hello';
$.ajax({
   type: "POST",
   url: "some.php",
   data: "js_var="+js_var,
   success: function(msg){
     alert( "Data Saved: " + msg );
   }
 });

PHP side

$js_var = isset($_POST['js_var']) ? $_POST['js_var'] : '';

Variant #2 (with page reload):

JS side

PHP side

$js_var = isset($_GET['js_var']) ? $_GET['js_var'] : '';
