25-63x Faster

Code generation at build time means zero runtime reflection. The only code-gen approach in PHP for DTOs.

Perfect IDE Support

Generated methods give you full autocomplete, go-to-definition, and refactoring support in any IDE.

TypeScript Generation

Generate TypeScript interfaces directly from your DTO configs. Keep frontend and backend types in sync.

Reviewable Code

Generated DTOs show up in pull requests. No hidden magic—review exactly what your DTOs look like.

JSON Schema Support

Bidirectional JSON Schema—both import and export. Bootstrap DTOs from APIs or generate documentation.

Multiple Config Formats

Define DTOs in PHP, XML, YAML, or NEON. XML includes XSD validation with IDE autocomplete.

Quick Example

Define your DTOs with the fluent PHP builder:

php

// config/dto.php
use PhpCollective\Dto\Config\{Dto, Field, Schema};

return Schema::create()
    ->dto(Dto::create('User')->fields(
        Field::int('id')->required(),
        Field::string('name')->required(),
        Field::string('email')->required(),
        Field::dto('address', 'Address'),
    ))
    ->dto(Dto::create('Address')->fields(
        Field::string('street'),
        Field::string('city'),
        Field::string('country'),
    ))
    ->toArray();

Generate and use:

bash

vendor/bin/dto generate

php

$user = UserDto::createFromArray($apiResponse);

$user->getName();           // string
$user->getAddress();        // AddressDto|null
$user->getAddressOrFail();  // AddressDto (throws if null)
