PHP Tag Engine is a library that allows you to
easily add tagging functionality to a PHP
application. It has a full AJAX front-end for
tagging as well as methods for programatically
adding tags in your code. The front-end tagging
interface even has auto-complete functionality
using the excellent Yahoo! Auto-Complete library.
There is a built-in cache to reduce database
queries. The code is fully documented in PHP Doc
format, and PHP Doc generated documentation is
available for download. It is fully
internationalized, including Javascript strings.
An English localization is included.
