Uses a 2-year decay window. **Popularity (30%)** — Total and monthly downloads, GitHub stars, and forks. Logarithmic scaling prevents top-heavy scores. **Community (15%)** — Contributors, dependents, forks, watchers, and maintainers. Measures real ecosystem engagement. **Maturity (30%)** — Project age, version count, PHP version support, and release stability. ### Release Activity Cadence Every ~43 days Recently: every ~10 days Total 16 Last Release 1157d ago PHP version history (2 changes)0.1.0PHP ^8.0 0.1.8PHP ^8.1 ### Community Maintainers ![](https://avatars.githubusercontent.com/u/11485189?v=4)[M.
