README

This library is an extremely fast and strictly typed object mapper built for modern PHP (8.2+). It seamlessly transforms data from formats like JSON, NEON, XML, YAML, arrays, and standard objects into well-structured PHP objects.

Ideal for developers who need reliable and efficient data mapping without sacrificing code quality or modern best practices.

Features

• Mapping source data into objects
• Mapping source data with a list of elements into a list of objects
• Initialize object via constructor, properties or methods
• Map nested objects, arrays of objects
• Class mapping for interfaces or other classes
• Custom root element for starting with the source data
• Auto-casting for float types (eu to us decimal separator)
• Target alias via Attribute for properties and methods

Supported Types

• null
• bool|?bool
• int|?int
• float|?float
• string|?string
• array
  • int[]
  • float[]
  • string[]
  • object[]
• object|?object
• enum|?enum

Supported Formats

optional formats are marked with an asterisk *

• array
• json
• neon*
• object
  • public property
  • public getters
  • method toArray()
  • attribute SourceData('...')
• xml
• yaml*

Installation

• Symfony Bundle

Usage

Minimal usage

use Wundii\DataMapper\DataMapper;

/**
 * DataConfig default settings
 * - ApproachEnum::SETTER - will use the constructor to map the data
 * - AccessibleEnum::PUBLIC - will use only public properties/methods
 * - classMap = [] - will not map any classes 
 */

$dataMapper = new DataMapper();

$testClass = $dataMapper->array($array, TestClass::class);
$testClass = $dataMapper->json($json, TestClass::class);
$testClass = $dataMapper->neon($neon, TestClass::class);
$testClass = $dataMapper->xml($xml, TestClass::class);
$testClass = $dataMapper->yaml($yaml, TestClass::class);

Usage with custom configuration

use Wundii\DataMapper\DataConfig;
use Wundii\DataMapper\DataMapper;
use Wundii\DataMapper\Enum\ApproachEnum;

$dataConfig = new DataConfig(
        approachEnum: ApproachEnum::PROPERTY,
        classMap: [
            DateTimeInterface::class => DateTime::class,
        ],
    );
$dataMapper = new DataMapper($dataConfig);

$testClass = $dataMapper->array($array, TestClass::class);
$testClass = $dataMapper->json($json, TestClass::class);
$testClass = $dataMapper->neon($neon, TestClass::class);
$testClass = $dataMapper->xml($xml, TestClass::class);
$testClass = $dataMapper->yaml($yaml, TestClass::class);
