ZF2和学说2转换的结果集，以阵列

Question

我使用Zend框架的2学说2.这是我的问题

以下对象返回数组

$results = $em->getRepository('MyProject\Domain\User')->find($id); 

返回：

array (size=4) 
    0 => 
    object(My\Entity\User)[3] 
     private 'id' => int 1 
     private 'firstName' => string 'joe' (length=3) 
     private 'lastName' => string 'smith' (length=5) 
    1 => 
     object(My\Entity\User)[3] 
     private 'id' => int 1 
     private 'firstName' => string 'joe' (length=3) 
     private 'lastName' => string 'smith' (length=5) 
    3 => 
    object(My\Entity\User)[3] 
     private 'id' => int 1 
     private 'firstName' => string 'joe' (length=3) 
     private 'lastName' => string 'smith' (length=5) 
    4 => 
     object(My\Entity\User)[3] 
     private 'id' => int 1 
     private 'firstName' => string 'joe' (length=3) 
     private 'lastName' => string 'smith' (length=5) 

我想将它转换为像这样的阵列阵列：

array (size=4) 
     0 => 
     array (size=3) 
     ['id'] => int 1 
     ['firstName'] => string 'joe' (length=3) 
     ['lastName'] => string 'smith' (length=5) 
     1 => 
     array (size=3) 
     ['id'] => int 1 
     ['firstName'] => string 'joe' (length=3) 
     ['lastName'] => string 'smith' (length=5) 
     2 => 
     array (size=3) 
     ['id'] => int 1 
     ['firstName'] => string 'joe' (length=3) 
     ['lastName'] => string 'smith' (length=5) 
     3 => 
     array (size=3) 
     ['id'] => int 1 
     ['firstName'] => string 'joe' (length=3) 
     ['lastName'] => string 'smith' (length=5) 

我曾尝试以下：

$resultsArray = new \Doctrine\Common\Collections\ArrayCollection($results); 
$resultsArray->toArray(); 

$resultsArray = new \Zend\Stdlib\ArrayObject($results); 
$resultsArray->getArrayCopy(); 

两个返回此：

array (size=4) 
    0 => 
    object(My\Entity\User)[3] 
     private 'id' => int 1 
     private 'firstName' => string 'joe' (length=3) 
     private 'lastName' => string 'smith' (length=5) 
    1 => 
     object(My\Entity\User)[3] 
     private 'id' => int 1 
     private 'firstName' => string 'joe' (length=3) 
     private 'lastName' => string 'smith' (length=5) 
    3 => 
    object(My\Entity\User)[3] 
     private 'id' => int 1 
     private 'firstName' => string 'joe' (length=3) 
     private 'lastName' => string 'smith' (length=5) 
    4 => 
     object(My\Entity\User)[3] 
     private 'id' => int 1 
     private 'firstName' => string 'joe' (length=3) 
     private 'lastName' => string 'smith' (length=5) 

我怎样才能做到这一点？推荐的方法是什么？

Answer 1

传统上，我写了一个自定义的库类，并调用getArrayResult()它

 $dql = 'MYDQLHERE'; 
     $query = $this->getEntityManager()->createQuery($dql); 
     $query->execute(); 
     $result = $query->getArrayResult(); 

里面，我相信你的另一种选择是定制的水化模式，虽然我没有与他们的经验。 http://docs.doctrine-project.org/en/latest/reference/dql-doctrine-query-language.html#custom-hydration-modes

Answer 2

最简单的形式，下面是你想要

$qb = $em->getRepository('My\Entity\User')->createQueryBuilder('User'); 

$result = $qb->getQuery()->getArrayResult(); 

通常你会使用一个定制的仓库，添加您的DQL查询，方法是描述在这里文档什么

http://docs.doctrine-project.org/en/2.0.x/tutorials/getting-started-xml-edition.html#entity-repositories

Answer 3

另一种方式来编写它，我用：

//at the top of custom repository class 
use Doctrine\Orm\Query; 

//in the method 
$dql = "SELECT u FROM MyProject\Domain\User u WHERE u.id = $id" 
$query = $entityManager->createQuery($dql); 
$users = $query->getResult(Query::HYDRATE_ARRAY); 
//knowing the code you provided, this should give you an array of four arrays
