The wild-card `?` is used to iterate over the entire subarray. **Examples:** ``` A --> $array['A'] A/B --> $array['A']['B'] A/?/B --> foreach($array['A'] as $k => $v) $array['A'][$k]['B'] ``` ### Health Score 23 — LowBetter than 27% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity16 Limited adoption so far Community7 Small or concentrated contributor base Maturity41 Maturing project, gaining track record Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio. 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. ### Community Maintainers ![](https://www.gravatar.com/avatar/a8713415b20b4be4cec8f8b22741e3cd05f76eee9e38de1de5bf32727349b7c5?d=identicon)[bshaffer](/maintainers/bshaffer) --- Top Contributors [![bshaffer](https://avatars.githubusercontent.com/u/103941?v=4)](https://github.com/bshaffer "bshaffer (5 commits)") ### Embed Badge ![Health badge](/badges/perimeter-array-transformer/health.svg) ``` [![Health](https://phpackages.com/badges/perimeter-array-transformer/health.svg)](https://phpackages.com/packages/perimeter-array-transformer) ``` PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
