如何将Doctrine Annotation Information转换为Array？

Question

我为Symfony 3.0中创建的Doctrine创建了以下清单实体对象。

简而言之，我如何才能访问通过注释放入实体的信息？

例如，companyID具有引用inversedBy =“location”的ManyToOne注释。这个特定的信息对我来说非常有用，所以我可以通过外键或父母关系来判断它是否是子女关系。

如果我能以某种方式获得关于我通过注释描述的实体的信息，那么这个信息会很棒。这可能吗？本质上，我正在寻找实体上的自省功能。

发现这个不知道这是否会帮助，但（http://tocacar.com/2013/01/25/doctrine2-object-introspection/）

Answer 1

要获取元数据的数组：

$cmf = $em->getMetadataFactory(); 
$metadata = $cmf->getMetadataFor(\AppBundle\Entity\Inventory::class); 
//Doctrine\ORM\Mapping\ClassMetadata instance 
//as array: 
$metadata = (array) $metadata; 

为了得到相逆的信息：

$metadata->getAssociationMapping('companyId')['inversedBy']; 
//as array 
$metadata['associationMappings']['companyId']['inversedBy']; 

你可以找到更多的信息on the docs。
