PHP Permutations
================

[](#php-permutations)

This PHP package provides functionalities for generating combinations and permutations. Initially inspired by [eoincampbell/combinatorics](https://github.com/eoincampbell/combinatorics), this package is an adaptation for PHP environments. While translating, some comments may have been lost; however, you can refer to the original files for those details.

Installation
------------

[](#installation)

Install this package via Composer:

`composer require nolin/permutations:dev-master`

Usage
-----

[](#usage)

Once installed, you can use it in your PHP code as follows:

```
// Include the library
use Nolin\Permutations\Permutations;

// Create a permutations object with an array of elements
$permutations = new Permutations([1, 2, 3, 4, 5]);

// Iterate through the permutations
foreach ($permutations as $permutation) {
    // Perform desired actions with each permutation
    // e.g., echo/print, store in an array, etc.
}
```

Variations Feature
------------------

[](#variations-feature)

Variations have been transformed into VariationsWithRepetition and VariationsWithoutRepetition. The C# VariationsWithoutRepetition feature, originally from the source material, was not quite fitting the intended result. As a result, an upgrade has been made to the current() method.
