It simplifies data transport between layers of your application, ensuring type safety and automatic mapping between `snake_case` (common in databases/APIs) and `camelCase` (standard in PHP). Installation ------------ [](#installation) ``` composer require phprise/data-transfer-object ``` Usage ----- [](#usage) ### Basic Usage [](#basic-usage) Define your DTO by extending `Phprise\DataTransferObject\TransferObject` and adding public typed properties. ``` use Phprise\DataTransferObject\TransferObject; class UserDto extends TransferObject { public string $name; public int $age; } // Create from array $data = ['name' => 'John Doe', 'age' => 30]; $dto = UserDto::fromArray($data); echo $dto->name; // John Doe echo $dto->age; // 30 // Convert back to array $array = $dto->toArray(); // ['name' => 'John Doe', 'age' => 30] ``` ### Snake Case Magic [](#snake-case-magic) The library automatically handles conversion between `snake_case` keys and `camelCase` properties. ``` class UserProfileDto extends TransferObject { public string $firstName; public string $lastName; } $data = [ 'first_name' => 'Alice', 'last_name' => 'Wonderland', ]; $dto = UserProfileDto::fromArray($data); echo $dto->firstName; // Alice // Export as snake_case array $snakeArray = $dto->toSnakeCaseArray(); // ['first_name' => 'Alice', 'last_name' => 'Wonderland'] ``` ### Nested DTOs [](#nested-dtos) You can nest DTOs. The library will recursively hydrate them. ``` class AddressDto extends TransferObject { public string $street; public string $city; } class CustomerDto extends TransferObject { public string $name; public AddressDto $address; } $data = [ 'name' => 'Bob', 'address' => [ 'street' => '123 Maker Lane', 'city' => 'Buildtown', ], ]; $dto = CustomerDto::fromArray($data); echo $dto->address->city; // Buildtown ``` ### DateTime Support [](#datetime-support) Strings in standard formats (ISO 8601 / RFC 3339) are automatically converted to `DateTimeImmutable` objects if typed as such. ``` class EventDto extends TransferObject { public string $title; public \DateTimeImmutable $date; } $data = [ 'title' => 'Conference', 'date' => '2023-10-27T10:00:00+00:00', ]; $dto = EventDto::fromArray($data); echo $dto->date->format('Y-m-d'); // 2023-10-27 ``` ### JSON Serialization [](#json-serialization) ``` $json = $dto->toJson(); // or $jsonSnake = $dto->toSnakeCaseJson(); $dto = UserDto::fromJson($json); ``` Philosophy ---------- [](#philosophy) We follow **The OTAKU Manifesto: Fluid Structure Design**. 1. **O** - Own your Discipline (Be strict with yourself) 2. **T** - Tools for Composition (Compose like Unix) 3. **A** - Armor the Core (Protect the heart of the business) 4. **K** - Keep Infrastructure Silent (Infrastructure is just a detail) 5. **U** - Universal Language & Contracts (Speak the user's language via clear contracts) Please read more about it in [PHILOSOPHY.md](PHILOSOPHY.md).
