Interfaces ---------- [](#interfaces) - [`CountableListInterface`](src/CountableListInterface.php): A list that can be iterated and counted. - [`HasItemCapableInterface`](src/HasItemCapableInterface.php): Something that can be checked for the existence of an item. - [`SetInterface`](src/SetInterface.php): A list that can be checked for a value. - [`CountableSetInterface`](src/CountableSetInterface.php): A set that can be counted. - [`MapInterface`](src/MapInterface.php): An iterable container. - [`CountableMapInterface`](src/CountableMapInterface.php): A countable map. - [`ContainerFactoryInterface`](src/ContainerFactoryInterface.php): A factory of `ContainerInterface` objects. - [`MapFactoryInterface`](src/MapFactoryInterface.php): A factory of `MapInterface` objects. - [`HasCapableInterface`](src/HasCapableInterface.php): Something that can check for a given key. - [`ContainerInterface`](src/ContainerInterface.php): A container implementing `HasCapableInterface`. - [`WritableContainerInterface`](src/WritableContainerInterface.php): A container that can have mappings added and removed. - [`WritableMapInterface`](src/WritableMapInterface.php): A map that can have mappings added and removed. - [`WritableSetInterface`](src/WritableSetInterface.php): A set that can have items added and removed. - [`ClearableContainerInterface`](src/ClearableContainerInterface.php): A container that can have its members cleared. ### Health Score 47 — FairBetter than 94% of packages Maintenance59 Moderate activity, may be stable Popularity30 Limited adoption so far Community17 Small or concentrated contributor base Maturity68 Established project with proven stability 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. ### Release Activity Cadence Every ~180 days Recently: every ~137 days Total 20 Last Release 56d ago PHP version history (5 changes)v0.1.0PHP ^5.3 | ^7.0 v0.3.0-alpha1PHP ^7.1 v0.3.0-alpha3PHP ^7.1 | ^8.0 v0.4.0-alpha1PHP ^7.4 | ^8.0 v0.5.0-beta1PHP ^8.1 ### Community Maintainers ![](https://www.gravatar.com/avatar/1894e91b32c9f80d8f30a42d360af6983a507f1cf2c621b7c9a0a0de14e011c5?d=identicon)[XedinUnknown](/maintainers/XedinUnknown) --- Top Contributors [![XedinUnknown](https://avatars.githubusercontent.com/u/1428973?v=4)](https://github.com/XedinUnknown "XedinUnknown (243 commits)") ### Code Quality TestsPHPUnit Static AnalysisPsalm Type Coverage Yes ### Embed Badge ![Health badge](/badges/dhii-collections-interface/health.svg) ``` [![Health](https://phpackages.com/badges/dhii-collections-interface/health.svg)](https://phpackages.com/packages/dhii-collections-interface) ``` ### Alternatives [symfony/dependency-injection Allows you to standardize and centralize the way objects are constructed in your application 4.2k431.1M7.5k](/packages/symfony-dependency-injection)[illuminate/contracts The Illuminate Contracts package. 705122.9M10.1k](/packages/illuminate-contracts)[illuminate/container The Illuminate Container package. 31178.1M2.0k](/packages/illuminate-container)[ecotone/ecotone Supporting you in building DDD, CQRS, Event Sourcing applications with ease. 558549.8k17](/packages/ecotone-ecotone)[civicrm/civicrm-core Open source constituent relationship management for non-profits, NGOs and advocacy organizations. 728272.9k20](/packages/civicrm-civicrm-core)[internal/dload Downloads binaries. 98142.7k10](/packages/internal-dload) PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
