What are the best practices for handling user interface updates in PHP applications without causing page reloads?

When handling user interface updates in PHP applications without causing page reloads, the best practice is to use AJAX (Asynchronous JavaScript and XML) to make asynchronous requests to the server for data updates or changes. This allows for dynamic updates to specific parts of the page without refreshing the entire page. 

<?php
// PHP code to handle AJAX request for updating UI without page reload

if(isset($_POST['data'])) {
    // Process the data received from the AJAX request
    $data = $_POST['data'];

    // Perform necessary operations or calculations

    // Return updated data to the client
    echo json_encode($updatedData);
}
?>
