This repository hosts an OpenSource book full of tips and tricks about Yii 2.0 PHP framework.
Here's the table of contents. We also have a rendered version at readthedocs.
Note: it's not the same book as Yii2 Application Development Cookbook - Third Edition published by PACKT.
The book is created by Yii community and edited by Alexander Makarov (@samdark), a core team member of the framework.
Feel free to pull request your own writings. I'll review it, provide feedback and merge the best possible way.
