README

The Mapper class under the Dalue namespace offers a powerful and flexible method for data transformation and restructuring. This class allows you to create a new structure from a given data set, optionally performing transformations on the data in the process.

Getting Started

Before you begin using the Mapper class, ensure that the library containing the StrObj\StringObjects class is installed. The Mapper class utilizes the functionalities provided by this class for data access and manipulation.

Installation

First, install the required packages via Composer:

composer require uuur86/dalue:0.1.1-beta

Example Usage

Below is an example of how to use the Mapper class:

use Dalue\Mapper;
use StrObj\StringObjects;

// Sample data set
$data = new StringObjects([
    'user' => [
        'id' => 1,
        'name' => 'John Doe',
        'email' => '[e-mail]',
        'details' => [
            'age' => 30,
            'city' => 'New York'
        ]
    ]
]);

// Defining the data structure we want to transform into.
$paths = [
    'userID' => '@data/user/id',
    'userName' => '@data/user/name',
    'userDetails' => [
        'userAge' => '@data/user/details/age',
        'userCity' => '@data/user/details/city'
    ]
];

// Using the Mapper::map function to perform the transformation.
$mappedData = Mapper::map($data, $paths);

print_r($mappedData);

Explanation

1. Data Initialization:
   • A sample data set is created using the StringObjects class.
2. Path Definition:
   • The structure we want to transform into is defined in the $paths array.
3. Data Transformation:
   • The Mapper::map function is used to transform the data according to the defined paths.

Output

The above example will produce the following output:

Array
(
    [userID] => 1
    [userName] => John Doe
    [userDetails] => Array
        (
            [userAge] => 30
            [userCity] => New York
        )
)

Advanced Usage

You can also perform more complex transformations by incorporating custom functions in the mapping paths. Here is an example:

use Dalue\Mapper;
use StrObj\StringObjects;

$data = new StringObjects([
    'user' => [
        'id' => 1,
        'name' => 'John Doe',
        'email' => '[e-mail]',
        'details' => [
            'age' => 30,
            'city' => 'New York'
        ]
    ]
]);

$paths = [
    'userID' => '@data/user/id',
    'userName' => '@data/user/name',
    'userEmail' => function($data) {
        return strtoupper($data->get('user.email'));
    },
    'userDetails' => [
        'userAge' => '@data/user/details/age',
        'userCity' => '@data/user/details/city',
        'description' => function($data) {
            return $data->get('user.details.age') . ' years old, lives in ' . $data->get('user.details.city');
        }
    ]
];

$mappedData = Mapper::map($data, $paths);

print_r($mappedData);

Output

The advanced example will produce the following output:

Array
(
    [userID] => 1
    [userName] => John Doe
    [userEmail] => [e-mail]
    [userDetails] => Array
        (
            [userAge] => 30
            [userCity] => New York
            [description] => 30 years old, lives in New York
        )
)
