In what scenarios would opening a new window with JavaScript to interact with a PHP file be a viable solution?

When you need to interact with a PHP file without refreshing the current page, opening a new window with JavaScript can be a viable solution. This can be useful for tasks such as submitting form data asynchronously, fetching data from a database, or performing server-side operations without disrupting the user experience on the current page. 

<?php
// sample PHP file (example.php)
if(isset($_POST['data'])) {
    // process data here
    $result = $_POST['data'] * 2;
    echo $result;
}
?>
