TutsPlus.com has continued their "Building Your Startup with PHP" series in this latest tutorial covering the use of email commands in their "Meeting Planner" example application.

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. [...] In the last tutorial, we began emailing meeting invitations which included numerous links for participants to respond, i.e. view the meeting page, accept all places and times, reject a place or time, etc.

In this tutorial, I'll review how I chose to construct and process those links in a secure, functional manner.

He then starts in on the idea of "commands" explaining a bit about what they are and what kind of commands are needed for the planner application. Code is included to create some of these commands and how to integrate them into the rest of the Yii-framework based application.
