问题描述
我正在尝试使用doctrine2执行查询,并需要它返回集合对象。
I am trying to execute a query using doctrine2 and need it to return a collection object.
简化的代码段:
$players = $this->getEntityManager()
->createQueryBuilder()
->select('p')
->from('...\Player', 'p')
->getQuery()
->getResult();
返回的对象是一个播放器数组。
The returned object is an array of Player.
关于说:
结果类型取决于什么,如何实现
On what does the result type depend and how can I achieve getting a collection object?
推荐答案
getResult()总是返回一个数组。如果要收集,必须将getResult()返回的数组传递给Doctrine的ArrayCollection
the getResult() always returns an array. If you want a collection, you must pass the array that is returned by getResult() to Doctrine's ArrayCollection
eg
use Doctrine\Common\Collections;
$result = $this->getEntityManager()
->createQueryBuilder()
->select('p')
->from('...\Player', 'p')
->getQuery()
->getResult();
$players = new Collections\ArrayCollection($result);
