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 50 — FairBetter than 95% of packages Maintenance74 Regular maintenance activity Popularity43 Moderate usage in the ecosystem Community22 Small or concentrated contributor base Maturity52 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 140d 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) ``` ### Alternatives [letournel/path-finder Path finder algorithm 142.0k](/packages/letournel-path-finder) PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
