{
81+
public int $id;

public string $name;

95+
If you have a DTO array, then you must specify the full path to the class in phpdoc `array<\DTO\ProductDTO>`.
96+
97+
This is done in order to know exactly which instance you need to create. Because Reflection does not provide out-of-the-box functionality for getting a `use *`. In addition to the `use *`, an alias can be prescribed, and this will be more difficult to track.
98+
```php
99+
class PurchaseDTO
100+
{
101+
/** @var array<\DTO\ProductDTO> $products Product list */
102+
public array $products;
103+
104+
/** @var \DTO\UserDTO $user */
105+
public UserDTO $user;
106+
}
107+
```

110+
$data = [
111+

112+

$purcheseDTO = plainToClass(PurchaseDTO::class, $data);

var_dump($purcheseDTO);
