What it is

Yii 2 is a full-stack PHP web framework designed for building fast, secure, and efficient applications with minimal configuration. It provides a Model-View-Controller (MVC) architecture, database ORM (Active Record pattern), form handling, validation, asset management, and a rich set of built-in components—all pre-configured with sensible defaults that work out of the box. Monolithic structure: framework/ directory contains the core engine with subdirectories for base classes (framework/base/), assets (framework/base/assets/), and database abstractions. Build tooling in build/ contains Ant-based build scripts and controllers (ClassmapController, ReleaseController, TranslationController)…

Start here

Open these first:

• framework/Yii.php — Primary entry point and service locator for the entire framework; defines the global Yii class.
• framework/base/Application.php — Core application lifecycle manager; initializes modules, handles bootstrapping, and manages error/exception handling.
• framework/base/Component.php — Foundation for property binding, event system, and behavior attachment; nearly all framework objects inherit from this.
• framework/base/Model.php — Base class for all data models; provides validation, attribute management, and serialization across ORM and form handling.
• framework/base/Controller.php — Base controller class managing action routing, filters, request/response lifecycle for web applications.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

1. Clone: git clone https://github.com/yiisoft/yii2.git && cd yii2
2. Install dependencies: composer install (composer.json and composer.lock are present)
3. Review framework/README.md and framework/Yii.php to understand the entry point
4. Build assets if needed: check build/build.xml for build targets (Ant-based)
5. Verify PHP 7.4+ is available: php --version

Daily commands:

Framework itself is a library, not a runnable server. To use Yii 2: (1) create a new project via composer create-project yiisoft/yii2-app-basic or yiisoft/yii2-app-advanced (not in this repo), (2) within that project,…

…shortened for this brief.

Key cautions & unknowns

• (1) PHP version floor: Minimum PHP 7.4 strictly enforced; code may use PHP 8 features (union types, named arguments) in newer branches—verify minimum version locally before upgrading. (2) Build system: Uses…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
