Notes on examples ----------------- [](#notes-on-examples) Since the recommendation is to use Strauss to prefix this library's namespaces, all examples will be using the `Boomshakalaka` namespace prefix. Acknowledgements ---------------- [](#acknowledgements) A number of array methods were ported over from [The Events Calendar](https://theeventscalendar.com) and the [Laravel Framework](https://github.com/laravel/framework). ### Health Score 51 — FairBetter than 96% of packages Maintenance82 Actively maintained with recent releases Popularity41 Moderate usage in the ecosystem Community22 Small or concentrated contributor base Maturity51 Maturing project, gaining track record Bus Factor1 Top contributor holds 50.9% 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. ### Release Activity Cadence Every ~69 days Recently: every ~105 days Total 14 Last Release 95d ago ### Community Maintainers ![](https://www.gravatar.com/avatar/e3171496e198834c638911ad3c3220bec77871cdf6557eaa9e2a58d16600a1a1?d=identicon)[bordoni](/maintainers/bordoni) ![](https://www.gravatar.com/avatar/70a2847a265444714b48c64eceb3ca742baa3a56757ce65b18bd7bbbbf910312?d=identicon)[dpanta94](/maintainers/dpanta94) ![](https://www.gravatar.com/avatar/97fd764aa710e8d8263a7e3b3fececdfd736b8aad8055227bf592ddf50ad15ba?d=identicon)[stellarwp](/maintainers/stellarwp) ![](https://www.gravatar.com/avatar/ec4ef25906386b60f5f66b3d03064e3bb700bedc94ee8558918565612c74aef3?d=identicon)[johnhooks](/maintainers/johnhooks) --- Top Contributors [![borkweb](https://avatars.githubusercontent.com/u/430385?v=4)](https://github.com/borkweb "borkweb (29 commits)")[![defunctl](https://avatars.githubusercontent.com/u/1066195?v=4)](https://github.com/defunctl "defunctl (17 commits)")[![tarecord](https://avatars.githubusercontent.com/u/6947218?v=4)](https://github.com/tarecord "tarecord (7 commits)")[![estevao90](https://avatars.githubusercontent.com/u/18039589?v=4)](https://github.com/estevao90 "estevao90 (4 commits)") ### Embed Badge ![Health badge](/badges/stellarwp-arrays/health.svg) ``` [![Health](https://phpackages.com/badges/stellarwp-arrays/health.svg)](https://phpackages.com/packages/stellarwp-arrays) ``` PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
