Yii3

Use the official Yii3 resources for framework guidance. This portal provides a separate place to discover packages and review their declared compatibility.

Official resources

Yii3 guide	Application concepts and development workflows
Yii3 API reference	Package APIs
Yii3 community cookbook	Recipes contributed to the Yii3 documentation project

These are external resources linked by the official Yii website. The portal does not maintain a copy of the Yii3 manual or represent the Yii team.

Find a package for your application

Use the Yii3 filter in the package catalog. Each entry records its own PHP requirement, compatibility evidence, and inspected source. Read that evidence alongside the upstream documentation before choosing a package.

Yii2 and Yii3 are distinct ecosystems. Neither membership in a project collection nor framework-independent PHP code establishes compatibility with a specific Yii3 integration. A lack of listings means the catalog has no reviewed entry for that selection; it is not a statement about the availability of packages elsewhere.

Contribute a Yii3 extension

Propose a package with its repository, license, documentation, PHP constraint, and the exact Yii3 dependencies or integration evidence. Record the release or commit that the evidence describes. Community authors keep their own attribution and support channels.
