Padraic Brady has noted that the latest release candidate of the HTMLPurifier software has been posted for download:

HTMLPurifer is possibly the most understated underpublicised quality library in PHP today. I consider it a fundamental standard library that is automatically included in every PHP web application I start these days.

This latest release candidate (their first!) includes updates on two major features - the use of autoloading and a change to the way you use the filters. Check out a demo of it in action or just download this latest release and try it out for yourself.

Ajaxian.com has pointed out a new tool that combines PHP and jQuery to make something similar to the Rails helpers (in relation to Prototype/Script.aculo.us).

PQuery is a set of helper classes for JQuery JavaScript library.This library allows you to easily integrate AJAX , Effects and other JQuery functionality into your PHP scripts.IT has a small foot print and is compatible with PHP4 and PHP5.

They've also included an example of the code to show how simple it can be as well as links to download the library, check out some other demos (including an Ajax demo, two Effects demos, and two simple applications - a chat and to-do list), as well as pointing you to the complete documentation for the project.
