Assigner 可以递归工作，因此可以将嵌套数组轻松转换为嵌套对象。支持 Laravel 集合。

此软件包对以下情况非常有用

1. 解析 JSON 为对象
2. 快速递归分配对象属性
3. DTO

安装

composer require php-utils/assigner

用法

你需要做的一切是

class YourClass implements Assigner\Contracts\Assignable {
    use Assigner\Traits\Assigner;
}

运行示例

./example.sh

示例

class Address implements Assignable {
    use Assigner;

    private $city;
    private $street;
}

class Person implements Assignable {
    use Assigner;

    private $firstName;
    private $lastName;
    private $address;
    private $friends;

    public function __construct()
    {
        $this->address = new Address;
        $this->initCollection('friends', static::class);
    }
}

$input = <<<JSN
{
  "first_name": "John",
  "last_name": "Doe",
  "address": {
    "city": "London",
    "street": "Baker"
  },
  "friends": [
    {
      "first_name": "Jack",

      "address": {

          "last_name":  "Brown"
        }
      ]
    }
  ]
}
JSN;

$person = new Person;
$person->assign(json_decode($input, true));

dump($person);
