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ReflectionObject变量中获取$property对象以获取有关该属性的一些额外信息（例如它的类和它继承自哪个类）。我怎样才能做到这一点？

e.g。

class A {
   /**
   * @var \Utils\WebService
   */
   public $prop;
}

现在，我得到了ReflectionClass（实际上是指＆＃39; A＆＃39;），我需要为$prop属性获取ReflectionClass / ReflectionObject。我需要稍后检查$prop的类型以及它扩展的超类型。

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());
