yii2

Yii 2 is a web framework for the PHP programming language. A framework is a foundation of reusable code that takes care of the common parts of building a web application, such as handling requests, talking to a database, and producing pages, so that developers do not have to write all of that from scratch each time. The README describes Yii 2 as fast, secure, and efficient, and says it comes pre-configured with reasonable defaults while still being flexible enough to adjust to your needs.

The README is short and mostly points to resources rather than explaining the framework in depth. For installation, it notes that the minimum required PHP version is 7.4 and that the framework works best with PHP 8, then directs you to the official step-by-step guide on the Yii website.

For learning the framework, it links to two main documents: a Definitive Guide that walks through usage, and a Class Reference that documents the code in detail. A PDF copy of the guide is available, along with a separate page for users upgrading from the older Yii 1.1 version, which summarizes what changed.

The rest of the README covers the project as a community effort. It lists places to take part, including discussion forums, a community Slack, and social media accounts. It explains how to contribute by reporting issues, translating documentation, or fixing bugs, and it gives a clear warning not to report security problems through public GitHub issues, pointing instead to a dedicated security page. It also shows the simple folder layout of the source code and offers a badge you can add to your own project to credit Yii, plus links for sponsoring the project financially.
