## Overview
PHP's `array_map()` function doesn't allow associative array key mutation. This package provides a function, `array_map_keys()`, which does.
The function iterates over an array and mutates each array item with the provided callback.
## Installation
Via Composer:
```
composer require aviator/array-map-keys
```
## Testing
Via Composer:
```
composer test
```
## Usage
An array:
```php
$input = [
[
'company' => 'Aviator Creative',
'owner' => 'Daniel Deboer',
'email' => 'daniel.s.deboer@gmail.com',
],
[
'company' => 'Widget Makers',
'owner' => 'Jane Doe',
'email' => 'jane@widgets.com',
],
];
```
A callback:
```php
$callback = function ($key, $value) {
return [
$value['owner'] => $value['email'];
];
};
```
The `array_map_keys` function:
```php
$results = array_map_keys($input, $callback);
```
The output:
```php
echo $results;
/*
[
'Daniel Deboer' => 'daniel.s.deboer@gmail.com',
'Jane Doe' => 'jane@widgets.com',
]
*/
```
