Data Mapper
===========

[](#data-mapper)

[![run-tests](https://github.com/jerodev/data-mapper/workflows/run-tests/badge.svg)](https://github.com/jerodev/data-mapper/workflows/run-tests/badge.svg) [![Latest Stable Version](https://camo.githubusercontent.com/c9705970f3f38bef5b1ccff66c7560c881c485a5793e908ae58660f3ca2bb859/687474703a2f2f706f7365722e707567782e6f72672f6a65726f6465762f646174612d6d61707065722f76)](https://packagist.org/packages/jerodev/data-mapper)

This package will map any raw data into a predefined strong-typed PHP object.

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

[](#installation)

The mapper has no external dependencies apart from PHP8.1 or higher. It can be installed using composer:

```
composer require jerodev/data-mapper
```

Basic mapping
-------------

[](#basic-mapping)

Let's start with the basics. The mapper will map data directly to public properties on objects. If these properties have types defined either using types introduced in PHP7.4 or through [PHPDoc](https://phpstan.org/writing-php-code/phpdoc-types), the mapper will attempt to cast the data to these types.

For example: imagine having an `Entity` class with the public properties `$id` and `$name`:

```
class User
{
    public int $id;
    public string $name;
}
```

To map data from an array we simply pass the class name and an array with data to the mapper.

```
$mapper = new \Jerodev\DataMapper\Mapper();
$entity = $mapper->map(User::class, [
    'id' => '5',
    'name' => 'John Doe',
]);

//    User {
//        +id: 5,
//        +name: "John Doe",
//    }
```

This is a simple example, but the mapper can also map nested objects, arrays of objects, keyed arrays, and even multi-level arrays.
