Serializer Package

A simple, powerful JSON serializer library for PHP inspired by Symfony components. Transform JSON data into PHP objects with ease.

Installation

composer require vigihdev/serializer

Quick Start

use Serializer\Factory\JsonTransformerFactory;

// Transform JSON file to objects
$transformer = JsonTransformerFactory::create(YourDTO::class);
$objects = $transformer->transformWithFile('data.json');

// Or transform JSON string
$json = '{"name": "John", "age": 30}';
$object = $transformer->transformJson($json);

Features

• ✅ Transform JSON to PHP objects
• ✅ Handle both single objects and arrays
• ✅ File-based and string-based transformation
• ✅ Symfony Serializer integration
• ✅ Proper error handling with custom exceptions
• ✅ Type safety with PHP 8.1+ features

Usage Examples

Basic DTO

class UserDto
{
    public function __construct(
        public readonly string $name,
        public readonly int $age,
        public readonly string $email
    ) {}
}

Transform from File

$transformer = JsonTransformerFactory::create(UserDto::class);
$users = $transformer->transformWithFile('users.json');

foreach ($users as $user) {
    echo $user->name . ': ' . $user->email;
}

Transform from JSON String

$json = '{"name": "Alice", "age": 25, "email": "alice@example.com"}';
$user = $transformer->transformJson($json);

echo $user->name; // "Alice"

Error Handling

use Serializer\Exception\TransformerException;

try {
    $transformer->transformWithFile('invalid.json');
} catch (TransformerException $e) {
    echo "Error: " . $e->getMessage();
}

Requirements

• PHP 8.1 or higher
