I'm actively maintaining the following software:
- Twitter-RSS-to-HTML, a PHP script that parses a Twitter user's RSS feed and displays updates as HTML.
- Weblog-Pinger, a PHP class library that can send update notification pings over XML-RPC services such as Weblogs.Com, Blo.gs, Ping-o-Matic and Technorati.
- Xml-Simple, a PHP class library that parses XML data. A script is included that demonstrates how to use the library to load the data into an array and display it on a web page.
