Version 0.2.0
-------------

[](#version-020)

> This library was extracted from the PinkCrab Plugin Framework (Perique)

Why?
----

[](#why)

Give access to a basic collection with all expected functionlaity, filtering, mapping, folding, sorting and comparing. But is also extendable for creating custom collections, which can be expanded and typed. A fairly simple, but extendable Collection.

Install
-------

[](#install)

> `composer install pink-crab/collection`

Basic Useage
------------

[](#basic-useage)

> See [`./docs`](./docs) for more details and examples.

```
$collection = new Collection(['1',2,'3']);
$collection->push(4);
$collection->apply(fn($e) => (string) $e);
var_dump($collection); // ['1','2','3','4'];
```

---

```
$collection = new Collection([1,2,3,4,5,6,7,8,9,10]);
$collection->filter(fn($e) => $e % 2 == 0);
var_dump($collection); // [2,4,6,8,10];
```

Extendable Traits
-----------------

[](#extendable-traits)

The Collection package comes with a few Traits which can be used when creating custom collections. These can either be created on the fly using anonymous classes or through defining them as full classes.

```
$indexed_collection = new class() extends \PinkCrab\Collection\Collection {
	use \PinkCrab\Collection\Traits\Indexed;
};

$indexed_collection->set( 'key1', 'value1' );
$indexed_collection->has( 'key1' ); //true
var_dump( $indexed_collection );

// As a full class.
class Indexed_Collection extends \PinkCrab\Collection\Collection {
	use \PinkCrab\Collection\Traits\Indexed;
};

$indexed_collection = new Indexed_Collection();
$indexed_collection->set( 'key1', 'value1' );
$indexed_collection->has( 'key1' ); //true
var_dump( $indexed_collection );
```
