PHP对象映射，可以将array/object映射为类对象。可做参数的传递、Request参数映射、Entity、Bean等。并可根据定义的映射对象生成API文档。
class TestMapping extends BaseMapping { /** @var int 总数 */ public int $total; public ?TestItem $item = null; /** @var \Xbyter\PhpObjectMappingTests\Data\TestItem[] 列表对象 */ public array $list = []; /** @var string 受保护的值，不会被设置 */ protected string $protected_key = 'protected value'; } class TestItem extends BaseMapping { /** @var string|null 标题 */ public ?string $title = null; /** * @var string|null 会返回装饰过的值 * @return TitleDecorator */ public ?string $decorate_title = null; } //装饰类 class TitleDecorator implements DecoratorInterface { public function decorate($value) { return sprintf("this is a decorated value: %s", $value); } } //映射对象，多维数组可用 TestMapping::fromList([[...], [...]]); $testMapping = TestMapping::fromItem([ 'total' => 10, 'item' => [ 'title' => 'a' ], 'list' => [ [ 'title' => 'b', 'decorate_title' => 'c', ] ], 'protected_key' => '受保护的字段不会被赋值', ]); //转为数组 $array = $testMapping->toArray(); var_dump($testMapping->total); //10 var_dump($testMapping->item->title); //a var_dump($testMapping->list[0]->title); //b var_dump($testMapping->list[0]->decorate_title); //this is a decorated value: c var_dump($testMapping->protected_key); //Error : Cannot access protected property $protected_key
