How can PHP be used to dynamically update a list of users in a separate frame after adding a new user?

To dynamically update a list of users in a separate frame after adding a new user, you can use AJAX in combination with PHP. When a new user is added, send a request to a PHP script that retrieves the updated list of users and returns it as a response. Then, use JavaScript to update the list in the separate frame with the new data without refreshing the page. 

// PHP script to retrieve and return updated list of users
<?php
// Code to add new user to database

// Code to retrieve updated list of users
$users = array("User1", "User2", "User3"); // Example list of users

// Return updated list of users as JSON
header('Content-Type: application/json');
echo json_encode($users);
?>
