A crud update operation is an AJAX function that sends a request to a database and updates it. Ajax is a library for sending requests to the server and getting responses back in a standardized way. Ajax calls are typically used when you need to send data from the client browser to the server or vice versa.

There are many benefits of using a php ajax crud update operation. One benefit is that it reduces load on your website by only updating what needs to be updated, when needed. Another benefit is that this method allows you to keep your website secure from malicious attacks, because the data stays on your server and not on the client's browser.
