**Memory efficient Cartesian Product implementation.**

It uses iterators in order to store only a specific tuple at a time, being able to compute even large combinations without affecting the memory footprint.

Install
-------

[](#install)

Via Composer

```
$ composer require th3n3rd/cartesian-product
```

Usage
-----

[](#usage)

The library can be used as an iterator:

```
use Nerd\CartesianProduct\CartesianProduct;

$cartesianProduct = CartesianProduct::empty()
    ->with(['a', 'b', 'c'])
    ->with(['d', 'e'])
;

// or you can use the `of` static method:
$cartesianProduct = CartesianProduct::of([
    ['a', 'b', 'c'],
    ['d', 'e'],
]);

foreach ($cartesianProduct as $index => $product) {
    printf("[%s] (%s)\n", $index, implode(',', $product));
}
```

You can also compute the whole result at once (not recommended for large sets):

```
$result = $cartesianProduct->toArray();
```

Testing
-------

[](#testing)

```
$ vendor/bin/phpunit
```
