1. INTRODUCTION TO THE YII FRAMEWORK, VERSION 2 LARRY ULLMAN, @LARRYULLMAN TRUE NORTH PHP NOVEMBER 2, 2012 YII.LARRYULLMAN.COM Friday, November 16, 12 Good afternoon and welcome to my presentation on the Yii framework.

2. YII IS NOT THE BEST PHP FRAMEWORK. Friday, November 16, 12 First, and most importantly, you should walk out of here knowing that Yii is not the best PHP framework.

[[GO THROUGH TRUE]] I think we all know there’s a huge benefit in knowing more than one framework. Perhaps that second framework should be Yii, if it’s not already.

6. WHAT YOU MIGHT LIKE MODEL-VIEW-CONTROLLER (MVC) ACTIVE RECORD (AR) & PHP DATA OBJECTS (PDO) FLEXIBLE AND EXTENDIBLE ALLOWS FOR ADVANCED USES SCALES WELL JQUERY BUILT-IN Friday, November 16, 12 Yii 1 requires PHP 5.1; Yii 2 will require PHP 5.3, which introduces namespaces & anonymous functions Active Record for Object Relational Mapping (ORM) Flexibility: swap ORM, db library, template library (e.g., to Twig), etc.
7.
