About ----- [](#about) Phunctional is heavily inspired by [Clojure](https://clojure.org/) and some other PHP libraries like [iter](https://github.com/nikic/iter), [compose](https://github.com/igorw/compose) and [felpado](https://github.com/pablodip/felpado). The main principles that we have in mind developing this library are: - A collection can be any iterable PHP object, arrays or generators - Favor composition vs inheritance - Be lazy when you can - Avoid state, state is (usually) evil! - Simplicity over easiness - Break the above rules if it makes sense All of this can be resumed with a word: **Immutability**. Installation ------------ [](#installation) To install it with composer: ``` composer require lambdish/phunctional ``` Simple usage ------------ [](#simple-usage) The first is to import every function you're going to use, for example: ``` use function Lambdish\phunctional\map; ``` And then you'll be able to use it: ``` map( function ($number) { return $number + 10; }, [1, 2, 3, 4, 5] ); // => [11, 12, 13, 14, 15] ``` And do something more complex like: ``` use function Lambdish\Phunctional\pipe; use const Lambdish\Phunctional\{filter_null, reverse, first}; $lastNonNullableValue = pipe(filter_null, reverse, first); $lastNonNullableValue(['first', null, 'other', 'last non nullable', null, null]); // => "last non nullable" ``` Here we're using the provided constants, that acts like an alias for the functions full qualified namespace (and therefore, are `callable`). Documentation ------------- [](#documentation) You can find the functions documentation [here](docs/docs.md). ### Health Score 41 — FairBetter than 89% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity39 Limited adoption so far Community28 Small or concentrated contributor base Maturity67 Established project with proven stability Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
