Large open source project in PHP seeks contributors

The developer community of Yii3 — one of the most popular third-generation PHP frameworks — has announced an expanded call for contributors. The project, which for many years has been a benchmark for performance and flexibility, is moving into an active phase of developing new modules and stabilizing the core. If you write in PHP and want to make a real contribution to open-source, now is the perfect time.

What is Yii3 and why is it important?

Yii3 is a modern PHP framework designed for rapid development of high-load web applications. Unlike its predecessor (Yii2), the third version has been completely rewritten with best practices in mind: strict typing, use of PSR interfaces, modular architecture, and full support for Dependency Injection.

Key features of Yii3 include:

Modularity — each component (e.g., routing, database handling, template engine) is shipped as a separate Composer package.
Modern standards — minimum PHP version 8.1+, attributes instead of annotations, readonly properties.
Performance — optimized autoloader and caching at the core level.
Flexibility — you can use only the components that your project actually needs.

The project is already used in production by several international companies, but the team is constantly looking for developers ready to help with new features, bug fixes, and documentation.

What tasks await contributors?

Currently, the following areas for contribution are open:

Developing new packages — creating integrations with popular services (Redis, RabbitMQ, GraphQL).
Testing — writing unit tests for existing code (coverage is still below 80%).
Documentation — translating and updating English documentation into Russian and other languages.
Refactoring — optimizing bottlenecks in the framework core.
Bug tracker — helping to process issues on GitHub.

To get started, you only need basic knowledge of PHP and experience with Git. All discussions take place in the public chat on Discord and in the repository issues at github.com/yiisoft.

How to join?

The onboarding process is as simple as possible:

Fork any repository from the Yii3 organization on GitHub.
Look at the list of labels marked good first issue — they are specifically marked for beginners.
Create a Pull Request with your changes.
Wait for a review from the maintainers (usually within 1-3 days).

Additionally, every two weeks the team holds online meetups where they discuss plans and help new participants understand the architecture.
