In what scenarios would using location.href or a new Image object be appropriate for passing JavaScript variables to PHP scripts?

When you need to pass JavaScript variables to PHP scripts, you can use location.href to send the data via URL parameters or create a new Image object to make a GET request to a PHP script with the variables in the query string. This is useful when you want to send data from the client-side to the server-side without using a form submission. 

<?php
if(isset($_GET['variable_name'])) {
    $variable_value = $_GET['variable_name'];
    // Use the variable_value in your PHP code
}
?>
