The NETTUTS.com website has a new tutorial posted that combines PHP and AJAX (using the the jQuery library specifically) to create a simple dynamic poll.

When you combine some neat functionality courtesy of PHP with the cleverness of jQuery you can produce some pretty cool results. In this tutorial we'll create a poll using PHP and XHTML, then make use of some jQuery Ajax effects to eliminate the need for a page refresh, and to give it a nice little bit of animation.

The PHP handles defining the question, answers and the functionality to load, submit and return the current results (number of votes) back to the javascript. The communication between the PHP and javascript is a JSON message made simple thanks to PHP's json_encode function.

You can download the source or check out a live demo to see how it all fits together.
