Answer 1

You have to pass it to your PHP script, either via AJAX or via a formular with a submit button.

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function(){}; // change
xhr.open("POST", "your-script.php");
xhr.send("x="+x);

And the PHP script can look like this:

<?php

$y = isset($_POST['x']) ? $_POST['x'] : '';
echo $y;

?>
