Symfony2，主义2：getResult对象 [英] Symfony2, Doctrine 2: getResult Object

问题描述

$posts = $em->find('Application\BlogBundle\Entity\Post',1);
print_r ($posts);

为什么要得到它？

Barii\BlogBundle\Entity\Post Object ( [id:Barii\BlogBundle\Entity\Post:private] => 1 [title:Application\BlogBundle\Entity\Post:private] => something [body:Application\BlogBundle\Entity\Post:private] => content  )

而不是像这样的简单数组：

instead of a simple array like this:

array ( [id] => 1,
        [title] => "something",            
        [body] => "content"  )

我在Symfony 2中使用它。

I use it with Symfony 2.

推荐答案

您在这里有几个选择。据我所知，默认情况下，您无法从实体存储库中找到数组形式的结果。相反，您可以执行以下两项操作之一：

You have a couple options here. As far as I know, you can't find results as arrays from entity repositories by default. Instead, you can do one of two things:

首先，您可以在自己的计算机上实现 toArray（）方法实体对象（可能通过映射的超类 ），它仅返回属性数组。

First, you could implement a toArray() method on your entity object (perhaps through a mapped superclass) that simply returns an array of properties.

第二，您可以使用Doctrine查询语言通过 getArrayResult（）获取所需的信息。 方法，也许像这样：

Second, you could use Doctrine Query Language to pull the information that you need using the getArrayResult() method, perhaps something like this:

$query = $em->createQuery('SELECT p FROM Application\BlogBundle\Entity\Post p WHERE p.id=:pid');
$query->setParameter('tid', $postId);
$result = $query->getArrayResult(); // shortcut for $query->getResult(Query::HYDRATE_ARRAY);

可以在此处。
