Yii 2.0. Release

After three years of intensive development and almost 10,000 commits, more than 300 authors released a stable version of the PHP framework Yii 2.0! Thank you for your support and patience!

As you may already know, Yii 2.0 has been rewritten from scratch. This decision was made because we wanted to get a great PHP framework that preserves the simplicity and extensibility of Yii and, at the same time, will use new technologies and features to become even better. Today we are pleased to announce that the goal has been achieved.

Next we look at the most interesting features of the new version. If you're in a hurry to try the framework in action, start by reading the section on Getting Started .

The most interesting

Follow the standards and use the latest technology.

Yii 2.0 uses PHP namespace and traits, PSR , Composer and Bower standards . All this makes working with the framework more enjoyable. Third-party libraries are now much easier to use.

Reliable foundation

As in 1.1, in Yii 2.0, properties of objects are supported through getters and setters, configurations , events, and behaviors . The new code is more efficient and expressive. For example, you can handle the event as follows:

$response = new yii\web\Response;
$response->on('beforeSend', function ($event) {
    //   "beforeSend"
});
