How can a PHP script interact with JavaScript functions to open a new window?

To open a new window using JavaScript from a PHP script, you can use the `echo` statement in PHP to output JavaScript code that will open the new window. You can create a JavaScript function that opens a new window and then call that function from your PHP script by echoing the function call.

<?php
echo '<script>';
echo 'function openNewWindow() {';
echo 'window.open("https://www.example.com", "_blank");';
echo '}';
echo 'openNewWindow();'; // Call the function to open the new window
echo '</script>';
?>
