Transforms raw arrays from a given source mapping to a target mapping and back again.

This package requires **PHP 7.1 or higher**.

Quick example. Given the following YAML mapping:

```
---
mapping:
  foo[int]:
    inverse: bar.baz[float]
    formula:
      direct: bar.baz / 1000
      inverse: foo * 1000

```

A php array that looks like this (1):

```
[
    'bar' [
        'baz' => 1000.0
    ],
];

```

... transforms to this (2) (`transform`):

```
[
    'foo' => 1;
];

```

... and can be transformed back to its original form (`reverseTransform`)\*

```
[
    'bar' [
        'baz' => 1000.0
    ],
];

```

Simple formulas and type definitions are some of the "advanced" features of array-transform. Please refer to the documentation for more details.

\*There are weird mapping cases where a `reverseTransform` is not possible. Refer to the documentation for details.
