In the latest post to her site, Lorna Mitchell walks you through the creation of a first Phing plugin, an extension to the popular PHP-based build tool.

I'm a huge fan of Phing and use it regularly for build and deployment tasks. Often, I'll ask about a plugin that I wish existed, and get a very courteous "patches welcome" from the nice people in the #phing channel on freenode. This has happened a few times, so I thought I should probably look at how to make a new phing plugin, this article shows you how to make the simplest thing I could think of: a simple "hello world" plugin.

She points you to the location to grab the latest version of the tool (the github repository) and how to define a configuration file for your test runs. Then she includes the sample code showing how to create the "HelloTask" plugin. It takes an input value of "name" and displays a greeting when executed. She shows the syntax for defining this in the XML build file and the sample result when executed.
