PHP, JSON and JavaScript Usage

Today i want to introduce you to jSON (JavaScript Object Notation), in short, it is a simple format designed to exchange data between different programming languages. I will show you how to create JavaScript object, convert it to JSON string, and send to PHP script, which will decode jSON string to readable format (for PHP).

Or something else? In this entry I'd like to discuss the three formats, with examples, and ask you which format you've used in your practical AJAX applications.
