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. In creating this presentation, I asked myself: What is it that I want to say about the Yii framework?
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.

FALSE •ARGUE THAT YII IS THE BEST FRAMEWORK •ARGUE THAT YII IS BETTER THAN X FRAMEWORK •CONVINCE YOU TO SWITCH FRAMEWORKS $MYGOALSTODAY === Friday, November 16, 12 So what am I here for? [[GO THROUGH FALSE]] I’m not a framework expert. I haven’t tried them all and I certainly haven’t mastered them all. So what am I doing here? [[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. For me, for those of you wondering, Yii is my first framework, and maybe Zend is my second maybe.

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.
