如何在PHP中从ReflectionProperty获取ReflectionObject对象

Question

我有一个ReflectionProperty对象使用以下代码:

$service = new ReflectionClass($this);
$properties = $service->getProperties();
$property = $properties[0];

我想从$property变量中获得ReflectionObject对象，以获得有关该属性的一些额外信息(例如它的类是什么以及它的类继承自哪些类)。我怎样才能做到这一点呢?

。

class A {
   /**
   * @var UtilsWebService
   */
   public $prop;
}

现在，我得到了ReflectionClass(实际上是指'A')，我需要得到$prop属性的ReflectionClass/ReflectionObject。我需要稍后检查$prop的类型是什么，以及它扩展了哪些超类型。

谢谢

class WebCrawler {
}
class WebService extends WebCrawler {
}

class A {
   /**
   * @var WebService
   */
   public $prop;
   public $variable = 'hello';
   function __construct()
   {
        $this->prop = new WebService();
   }
}

// reflection
$obj = new A();
$reflectionObject = new ReflectionObject($obj);

// get all public and protected properties
$properties = $reflectionObject->getProperties(ReflectionProperty::IS_PUBLIC);
$properties = array_merge($properties, $reflectionObject->getProperties(ReflectionProperty::IS_PROTECTED));
var_dump($properties);

// create the array similar to what you asked for
$data = [];
foreach ($properties as $property) {
   $name = $property->name;
   $data[$name] = $obj->{$name};
}
var_dump($data);

// get info which class was inherited to the class defined in A::prop property
$reflectedObjectFromProperty = new ReflectionObject($data['prop']);
var_dump($reflectedObjectFromProperty->getParentClass());
