php-laravelHow can I use DTOs in a Laravel PHP project?
DTOs (Data Transfer Objects) are objects that are used to transfer data between the application's layers. In a Laravel PHP project, they can be used to map data from the database to the application's domain objects.
For example, the following code block creates a DTO class that maps data from the users
table:
class UserDTO
{
public $id;
public $name;
public $email;
public function __construct($data)
{
$this->id = $data->id;
$this->name = $data->name;
$this->email = $data->email;
}
}
The DTO can then be used to create a domain object:
$userDTO = new UserDTO($data);
$user = new User($userDTO);
Code explanation

class: maps data from theusers
