How can one ensure data consistency when using jQuery UI Sortable and mySQL in a PHP application?

When using jQuery UI Sortable to reorder items and storing the order in a mySQL database in a PHP application, data consistency can be ensured by updating the database with the new order after the sorting operation is completed. This can be achieved by sending an AJAX request to a PHP script that updates the database with the new order of items. 

<?php

// Assuming the AJAX request sends the new order as a comma-separated list of item IDs
$newOrder = $_POST['newOrder'];

// Split the comma-separated list into an array
$newOrderArray = explode(',', $newOrder);

// Update the database with the new order
foreach($newOrderArray as $key => $itemID) {
    $sql = "UPDATE items SET order = $key WHERE id = $itemID";
    // Execute the SQL query
}

?>
