What to Expect from Yii 2.0

In this post i will explain What to Expect from Yii 2.0. The latest version of Yii 2 is 2.0.0, released on October 12, 2014. It’s aimed to become a state-of-the-art of the new generation of PHP framework. Yii 2.0 is not compatible with 1.1. Yii 2.0.0 is a complete rewrite of its previous version Yii 1.1 which is one of the most popular PHP frameworks.

Requirements

The usage of namespaces and traits upped the requirements to PHP 5.4. Additionally, you’ll need the mb_string, PDO and intl extensions when you start developing. This should not be a problem if you run your own server, but might be if you’re on a shared environment. Of course, in time, that issue will disappear.

Feathures :

• Quick prototyping with support for common APIs for ActiveRecord;
• Response format negotiation (supporting JSON and XML by default);
• Customizable object serialization with support for selectable output fields;
• Proper formatting of collection data and validation errors;
• Efficient routing with proper HTTP verb check;
• Support for OPTIONS and HEAD verbs;
• Authentication;
• Authorization;
• Support for HATEOAS;
• HTTP Caching;
• Rate limiting.

Conclusion

The documentation quality for Yii 2.0 improved from Yii 1.1. I had a hard time figuring stuff out when I started with Yii 1.1 a few years ago and I feel the documentation is more extensive than before.
