Yii 2.x and 1.x differences and yii2.0 installation

There is a similar problem: http://www.zhihu.com/question/22924271/answer/23085751

The general idea will not change, the development process changes is not very big.
What's changed is that
1, Yii2 brought into the PHP5.4 characteristics, introduced the namespace to resolve the naming conflict, so the base class will not start with the C word
2. instead of inheriting all classes from component component, choose to inherit object and component ( also inherited from object, but with event functionality, and behavior functionality for extensions)
3, more MVC, the original view layer is basically a controller directly included in, now have the view of the class to control, so the view layer in the use of controller to bring the parameters of a slightly different way.
4, YII2 basic version (looks and 1 similar) and Advanced Edition (sub-foreground and backstage), advanced version is more suitable for the development of large-scale projects.
5, the other is the details of changes, such as Block assignment (basic to collect form data) more convenient. The installation is finished with the bootstrap style, and so on.
There are, of course, many other features that you can refer directly to Yii's updated documentation on GIT:
Yii2/docs/guide/upgrade-from-v1.md at Master Road Yiisoft/yii2 Road GitHub

Yii Basic and Advanced differences:

It's not quite the difference, actually. Yii2-app-basic has only one web app, and yii2-app-advanced is the default with two Web apps with foreground and background, integrates two apps into one project, and then uses the common app to store some of the things that are common to both apps. Some of the differences are explained in the documentation on the official website:
