Matthew Turland notes that the second part of his "IRC Bots in PHP" series of articles has been posted to the C7Y community site (from php|architect).

The precursor to this article introduced some background and an overview of the design for the Phergie project as an example of the concepts involved in a PHP IRC bot implementation. This article will go further into the topic of plugins including descriptions of those that are commonly needed to make a bot fully functional as well as the commonly needed core features to support plugin development.

In part one he set up some of the foundation code and explained some of the thought behind the structure of the bot. In this part he gets more into the heart of the bot, showing how to define functions for common IRC actions (join/part/ping/etc) and how he made a plugin system to handle custom actions. He also mentions topics like memory usage, data storage methods and some of the "niceties" he included.

Matthew Turland has been working on a project based on an idea he and Ben Ramsey thought up - a wrapper around the libircclient libraries to make IRC interface simple. As a result, Matthew turned it into a more practical application - you can call her Phergie.

I had toyed with some previous iterations of Phergie, some Python-based and later some PHP-based, before I finally got an API design I was happy with.

The source for the bot can be downloaded from its subversion repository and you can find out more about it on its Trac site. Also, if you feel like chatting about it, you can head over to the #phergie channel on the Freenode IRC network.
