Lightweight collection library -- by, [Chris Kankiewicz](https://www.ChrisKankiewicz.com)

Requirements
------------

[](#requirements)

- [PHP](https://php.net) >= 5.6

Install with Composer
---------------------

[](#install-with-composer)

```
composer require phlak/collection
```

Initializing the Client
-----------------------

[](#initializing-the-client)

First, import Collection:

```
use PHLAK\Collection;
```

Then pass an array of items to the `Collection` class or the static `make` method:

```
$collection = new Collection\Collection(['foo', 'bar', 'baz']);

// or

$collection = Collection\Collection::make(['foo', 'bar', 'baz']);
```

Usage
-----

[](#usage)

Iterate over each item in a collection and perform an action via a Closure:

```
$collection->each(Closure $function);
```

Map each item of the collection to a new value via a Closure:

```
$collection->map(Closure $function);
```

Filter the items in a collection by returning only the items where the Closure returns true:

```
$collection->filter(Closure $function);
```

Filter the items in a collection by returning only the items where the Closure returns `false` (opposite of the `filter` method):

```
$collection->reject(Closure $function);
```

Reduce a collection down to a single item by iterating over the Closure until a single item remains:

```
$collection->reduce(Closure $function, $initial);
```

Sum all the items in a collection and return the value:

```
$collection->sum(Closure $function, $initial);
```
