Yii

Is there any point in learning YII 2 to look into books on the first version of the framework?
Is it very different to work with them?
There are a lot of materials for the first version of the materials, but you still need to search for the second (

Answer 1

It’s better to use the Yii2 manuals, the differences in the framework versions are very significant

Answer 2

On the second it is necessary to read docks.
In the docks, everything is simple and clear.
In general, of course, you can peep ....
For example, we found an implementation of a case with CModel::findAllByAttributes() (I don’t remember the exact name already).
Typed in the search, find all by attributes YII2, read the documentation and how to start.

Answer 3

in books on frameworks, it doesn’t make much sense initially. Read documentation and read more books (classics like Fowler, Kent Beck, etc.)

Answer 4

It makes no sense. The second is quite different from the first. Right now there are a lot of training videos on YouTube, but I know only one book www.ozon.ru/context/detail/id/31921738
