通过学说将结果作为数组（水合物数组）获取时，如何获取关联实体？

Question

I am fetching data from the mysql database with doctrine:

$array = $this->em->getRepository(Documents::class)->findAll();

This is the output:

For my case I want to fetch an array directly, so I created a function:

$array = $this->em->getRepository(Documents::class)->getArray();

repository:

   public function getArray()
    {
      return   $this->getEntityManager()
               ->getRepository(Documents::class)
               ->createQueryBuilder('e')
               ->select('e')
               ->getQuery()
               ->getResult(\Doctrine\ORM\Query::HYDRATE_ARRAY);
      }

The array is created, but some fields are missing:

How can I also fetch pages and products? And I would like my data to be shown as a date +"timestamp": "02.12.2019"

Answer 1

Forgot about core class that will require another setup

Just use getArrayResult() function instead of getResult() . It returns an array of all data

$query = $em->createQuery("SELECT test FROM namespaceTestBundle:Test test");
$tests = $query->getArrayResult();

Query#getResult(): Retrieves a collection of objects. The result is either a plain collection of objects (pure) or an array where the objects are nested in the result rows (mixed).

Query#getArrayResult(): Retrieves an array graph (a nested array) that is largely interchangeable with the object graph generated by Query#getResult() for read-only purposes.

I Just tested that returns all result of data as an array nested:

Second soluton in other answer will work as well but they works different ways:

Also see this answer https://stackoverflow.com/a/17499629/12232340 And repository

According to this EntityRepository class , findAll don't take multiple arguments.

You need to do a "fetch-join" by adding it to the select:

public function getArray()
{
    return $this->getEntityManager()
        ->getRepository(Documents::class)
        ->createQueryBuilder('e')
        ->select('e', 'p')
        ->leftJoin('e.products', 'p')
        ->getQuery()
        ->getResult(\Doctrine\ORM\Query::HYDRATE_ARRAY);
}
