# KeyArray

Allowing you to use arrays as keys for associative arrays.

_Only supports flat arrays of scalar values._

## Installation

```bash

composer require hedronium/key-array

```

## Usage

Just Instantiate the class, or call the `KeyArray::array()` method to

instantiate it.

```PHP

use Hedronium\KeyArray\KeyArray;

$arr = new KeyArray;

// or

$arr = KeyArray::array();

```

then proceed to use it like a normal array.

```PHP

$arr[[]]              = 'The void in my heart.';

$arr[['a']]           = 'AYY';

$arr[['b']]           = 'BEE';

$arr[['a', 'b']]      = 'AYY-BEE';

$arr[['a', 'b', 'c']] = 'AYY-BEE-CEE';

```

iteration with `foreach` works too.

```PHP

foreach ($arr as $key => $val) {

	echo str_pad(implode(' -> ', $key), 20, ' ', STR_PAD_LEFT);

	echo ' = ';

	echo $val;

	echo PHP_EOL;

}

////// OUTPUT: /////////////////////////

//             = The void in my heart.

//           a = AYY

//      a -> b = AYY-BEE

// a -> b -> c = AYY-BEE-CEE

//           b = BEE

```
