Lambdish's Phunctional is a little library that tries to bring to PHP some aspects of functional programing with __util high order functions__ and __functions for manage iterables__.




## 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

To install it with composer:

```

composer require lambdish/phunctional

```

## Simple usage

The first is to import every function you're going to use, for example:

```php

use function Lambdish\phunctional\map;

```

And then you'll be able to use it:

```php

map(

    function ($number) {

        return $number + 10;

    },

    [1, 2, 3, 4, 5]

);

// => [11, 12, 13, 14, 15]

```

And do something more complex like:

```php

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`).
