I’ve been building custom Twitter engagement systems for clients since 2009, and now I’ve combined all of my favorite techniques and tools into a new book available on Amazon:
amazon.com/dp/0989875806

Just as with my 140dev Twitter Framework code and my ebooks on topics like OAuth, the code in this book uses PHP and MySQL. It shows how to capture tweets, mentions, retweets, tags, URLs, friends and followers. There is a complete report system for sharing this information with clients. A range of automated engagement tools, such as auto-tweeting, automatic DMs, and other forms of automation are included.

This entire engagement system is fully compliant with Twitter’s API version 1.1, and the latest version of the Terms of Service.

I’ve also made all of the source code from the book available for free download under the MIT open source license:
