You might know that I am involved in the [CakePHP framework](http://www.cakephp.org/) project, and I’m developing web sites with it now.
On the IRC channel today, I was alerted to the existence of the Bindings sister project. Now they have an example up, for all to see. Data Bindings v0.1 Example is a piece of very easy interaction between your PHP and the HTML the user manipulates.
Take a look at the “color box” example – yummy.
