A DTO, or Data Transfer Object, is a design pattern used to transfer data between different layers or subsystems of an application. Its main function is to encapsulate data and minimize the number of calls to the database or other services.

Key features of DTOs:

- Simplicity: DTOs are simple objects that only contain data and no business logic.
- Encapsulation: DTOs encapsulate data, allowing you to control how information is accessed and modified.
- Efficiency: DTOs can improve performance by reducing the amount of data transferred between layers.
- Decoupling: DTOs help decouple different layers of an application, making code maintenance and evolution easier.

Some use cases:

- When you need to transfer data between different layers of an application, such as the presentation layer and the data layer.
- When you need to expose data through an API.
- When you need to optimize the performance of your application by reducing the amount of data being transferred.

Instalation
===========

[](#instalation)

**Via Composer**

```
composer require matephp/dto
```

Documentation
=============

[](#documentation)

Define DTO properties
---------------------

[](#define-dto-properties)

Properties can be set in the class definition or in the constructor ([Constructor Property Promotion](https://wiki.php.net/rfc/constructor_promotion))

```
use Mate\Dto\Dto;

class MyDto extends Dto
{
    public string $property1;
    public string $property2;
}

// or

class MyDto extends Dto
{
    public function __constuct(
        public string $property1,
        public string $property2
    ) {
    }
}
```

DTO instantation
----------------

[](#dto-instantation)

You can create DATA in different ways:

**Using `constructor`**

```
// ...

$dto = new MyDto(
    property1: 'value 1',
    property2: 'value 2',
);
```

**From array using `fromArray` static method**

```
// ...

$data = [
    "property1" => 'value 1',
    "property2" => 'value 2',
];

$dto = MyDto::fromArray($data);
```

**From object using `fromObject` static method**

```
// ...

$data = new stdClass();
$data->property1 = "value 1";
$data->property2 = "value 2";

$dto = MyDto::fromObject($data);
```

**From json string using `fromJson` static method**

```
// ...

$obj = new stdClass();
$obj->property1 = "value 1";
$obj->property2 = "value 2";

$data = json_encode($obj);

$dto = MyDto::fromJson($data);
```

**from other DTO instance using `fromDto` static method**

```
// ...

$otherDto = new MyDto(
    property1: 'value 1',
    property2: 'value 2',
);

$dto = MyDto::fromDto($otherDto);
```

Creating DTOs with dynamic properties (Flexible DTO)
----------------------------------------------------

[](#creating-dtos-with-dynamic-properties-flexible-dto)

To create a DTO that allows defining properties dynamically, the [attribute](https://www.php.net/manual/en/language.attributes.php) `#[Flexible]` is used

```
use Mate\Dto\Dto;
use Mate\Dto\Attributes\Flexible;

#[Flexible]
class MyFlexibleDTo extends Dto
{
    public function __constructor(
        public string $property1,
        public string $property2
    ) {
    }
}

$dto = new MyFlexibleDTo(
    property1: 'value 1',
    property2: 'value 2',
    property3: 'value 3'
);

echo $dto->property3; // print: value 3
```

When creating a DTO with dynamic properties but not setting the `#[Flexible]` attribute, an exception of type `Mate\Dto\Exceptions\NotFlexibleException` is thrown.

Access DTO data
---------------

[](#access-dto-data)

DTO data can be accessed as a property of an object or through array syntax

```
// ...

$dto = new MyDto(
    property1: 'value 1',
    property2: 'value 2',
);

echo $dto->property1; // print: value 1
echo $dto->property2; // print: value 2

echo $dto['property1']; // print: value 1
echo $dto['property2']; // print: value 2
```

**Uninitialized properties**

When an attribute is called that was not initialized, an `\Error` exception is thrown.

```
// ...

$dto = new MyDto(
    property1: 'value 1',
);

echo $dto->property2; // throw: \Error exception
```

**Properties with default value**

When a value is not sent to a property, the default value is used if it has one.

```
use Mate\Dto\Dto;

class MyDto extends Dto
{
    public function __constructor(
        public string $property1,
        public string $property2 = 'value 2'
    ) {
    }
}

$dtoA = new MyDto(
    property1: 'value 1',
);

$dtoB = new MyDto(
    property1: 'value 1',
    property2: 'other value'
);

echo $dtoA->property2; // print: value 2
echo $dtoA->property2; // print: other value
```

**Nullable Properties**

When a value is not sent to a nullable property it is automatically set to `null`.

```
use Mate\Dto\Dto;

class MyDto extends Dto
{
    public string $property1;
    public ?string $property2;
}

$dtoA = new MyDto(
    property1: 'value 1',
);

$dtoB = new MyDto(
    property1: 'value 1',
    property2: 'value 2';
);

echo $dtoA->property2; // print: null
echo $dtoB->property2; // print: value 2
```

**Ignored attributes**

You can ignore attributes so that they are not initialized and are not considered.

```
use Mate\Dto\Dto;
use Mate\Dto\Attributes\Ignored;

class MyDto extends Dto
{
    #[Ignored]
    public string $property1;
    public string $property2;
}

$dto = new MyDto(
    property1: 'value 1',
    property2: 'value 2',
);

echo $dto->property1; // throw: \Error exception
```

Transforming data
-----------------

[](#transforming-data)

You can convert your DTO to some formats:

**To array**

```
// ...

$dto = new MyDto(
    property1: 'value 1',
    property2: 'value 2',
);

echo print_r($dto->toArray, true);
// print:
// Array
// (
//     [property1] => value 1
//     [property2] => value 2
// )
```

If you do not need to transform the attributes of the DTO type into an array, you can set it to false.

```
use Mate\Dto\Dto;

class MyDtoWithoutNestedToArray extends Dto
{
    protected bool $nestedToArrayEnabled = false;
    // ...
}
```

**To database**

```
// ...

class Client extends Dto
{
    public int $id;
    public int $userId;
}

$dto = new MyDto(
    id: 1,
    userId: 2,
);

echo print_r($dto->toDatabase, true);
// print:
// Array
// (
//     [id] => 1
//     [user_id] => 2
// )
```

**To JSON string**

```
// ...

$dto = new MyDto(
    property1: 'value 1',
    property2: 'value 2',
);

echo print_r($dto->toJson, true);
// print: {"property1":"value 1","property2":"value 2"}
```

**To string**

```
// ...

$dto = new MyDto(
    property1: 'value 1',
    property2: 'value 2',
);

echo print_r((string) $dto, true);
// print: {"property1":"value 1","property2":"value 2"}
```
