Anonymous array

In case you need to convert an array of data into an array of class objects, you can implement this using the transformCollection method.

$data = [
  ['id' => 1, 'name' => 'phone'],
  ['id' => 2, 'name' => 'bread'],
];
$products = ClassTransformer::transformCollection(ProductDTO::class, $data);

As a result of this execution, you will get an array of ProductDTO objects:

array(2) {
  [0]=>
      object(ProductDTO) {
        ["id"]=> int(1)
        ["name"]=> string(5) "phone"
      }
  [1]=>
      object(ProductDTO) {
        ["id"]=> int(2)
        ["name"]=> string(5) "bread"
      }
}

You may also need a piecemeal transformation of the array. In this case, you can pass an array of classes, which can then be easily unpacked.

$userData = ['id' => 1, 'email' => 'test@test.com', 'balance' => 10012.23];
$purchaseData = [
    'products' => [
        ['id' => 1, 'name' => 'phone'],
        ['id' => 2, 'name' => 'bread'],
    ],
    'user' => ['id' => 3, 'email' => 'fake@mail.com', 'balance' => 10012.23],
];

$result = ClassTransformer::transformMultiple([UserDTO::class, PurchaseDTO::class], [$userData, $purchaseData]);

[$user, $purchase] = $result;
var_dump($user);
var_dump($purchase);

Result:

object(UserDTO) (3) {
  ["id"] => int(1)
  ["email"]=> string(13) "test@test.com"
  ["balance"]=> float(10012.23)
}

object(PurchaseDTO) (2) {
  ["products"]=>
  array(2) {
    [0]=>
    object(ProductDTO)#349 (3) {
      ["id"]=> int(1)
      ["name"]=> string(5) "phone"
    }
    [1]=>
    object(ProductDTO)#348 (3) {
      ["id"]=> int(2)
      ["name"]=> string(5) "bread"
    }
  }
  ["user"]=>
  object(UserDTO)#332 (3) {
    ["id"]=> int(3)
    ["email"]=> string(13) "fake@mail.com"
    ["balance"]=> float(10012.23)
  }
}
