# Combinatorics

[![Build Status](https://travis-ci.org/kevinsimard/combinatorics.svg)](https://travis-ci.org/kevinsimard/combinatorics)

## Usage

You may add new elements to the list by using the `add` method:

```php

$instance = new Combinatorics(["foo", "bar"]);

$instance->add("baz");

$instance->add("qux");

// ["foo", "bar", "baz", "qux"]

```

You may also want to reset the list of elements by calling the `reset` method:

```php

$instance = new Combinatorics(["foo", "bar"]);

$instance->reset();

// []

```

### Permutations

```php

$elements = ["foo", "bar", "baz"];

$instance = new Combinatorics($elements);

foreach ($instance->permutations() as $value) {

    ...

}

// OR

foreach (Combinatorics::permutations($elements) as $value) {

    ...

}

// [

//     ["foo", "bar", "baz"],

//     ["bar", "foo", "baz"],

//     ["bar", "baz", "foo"],

//     ["foo", "baz", "bar"],

//     ["baz", "foo", "bar"],

//     ["baz", "bar", "foo"]

// ]

```
