DTO Playground

Paste JSON data and instantly see the generated DTO configuration. This helps you quickly bootstrap DTOs from API responses or existing data structures.

DTO Name: Output: PHP BuilderXMLYAML

JSON Input

{ "id": 1, "name": "John Doe", "email": "john@example.com", "address": { "street": "123 Main St", "city": "New York", "zipCode": "10001" }, "roles": ["admin", "user"], "metadata": { "createdAt": "2024-01-15", "active": true } }

DTO Configuration

<?php

use PhpCollective\Dto\Config\Dto;
use PhpCollective\Dto\Config\Field;
use PhpCollective\Dto\Config\Schema;

return Schema::create()
    ->dto(Dto::create('Address')->fields(
        Field::string('street'),
        Field::string('city'),
        Field::string('zipCode'),
    ))
    ->dto(Dto::create('Metadata')->fields(
        Field::string('createdAt'),
        Field::bool('active'),
    ))
    ->dto(Dto::create('Object')->fields(
        Field::int('id'),
        Field::string('name'),
        Field::string('email'),
        Field::dto('address', 'Address'),
        Field::array('roles'),
        Field::dto('metadata', 'Metadata'),
    ))
    ->toArray();

This is a simplified preview. The actual Schema Importer supports JSON Schema, OpenAPI, and more advanced type inference.

How It Works

1. Paste JSON — Any valid JSON object
2. Choose format — PHP Builder, XML, or YAML
3. Copy output — Use in your project

Tips

• Nested objects become separate DTOs
• Arrays of objects become collections
• Field names are preserved as-is (the actual generator converts to camelCase)

For Production Use

This browser-based tool provides a quick preview. For full functionality including:

• JSON Schema parsing with $ref resolution
• OpenAPI document support
• External file references
• Type inference from multiple examples

Use the CLI importer:

# From JSON data
php -r "echo (new PhpCollective\Dto\Importer\Importer())->import(file_get_contents('data.json'));"

# Or save to file
vendor/bin/dto import data.json --output=config/dto.php
