TutsPlus.com has posted the latest part in their "Building Your Startup with PHP" series today with a focus on delivering notifications to your users when meeting information is updated.

This tutorial is part of the Building Your Startup With PHP series on Envato Tuts+. In this series, I'm guiding you through launching a startup from concept to reality using my Meeting Planner app as a real-life example. Every step along the way, I'll release the Meeting Planner code as open-source examples you can learn from. I'll also address startup-related business issues as they arise.

In the prior episode, I described building the infrastructure for tracking changes to meetings so we would know how to share updates with participants. In this episode, I'll cover monitoring the log and delivering email notifications of changes.

They start with a look at monitoring for updates to current meetings via a "actionFrequent" method and the code required to locate and notify the correct people of the updates. Next up is the logging of these changes to the audit log and pulling a history of the meeting to show what actually changed. Finally there's code to deliver the actual update email.
