How can I turn an object into an array (Symfony)? - arrays

Question

This is how I create my array fields:
public function index($slug, Request $request, UserPasswordEncoderInterface $passwordEncoder)
{
$page = $this->getDoctrine()->getRepository(Pages::class)->findOneBy(['slug'=>$slug]);
$fields = (array) $page;
return $this->render('mypage.html.twig', ['page' => $page, 'fields' => $fields]);
}
The output is:
array:3 [▼
"\x00App\Entity\Pages\x00id" => 3
"\x00App\Entity\Pages\x00name" => "cat"
"\x00App\Entity\Pages\x00color" => ""
]
But I actually need this result:
array:3 [▼
"id" => 3
"name" => "cat"
"color" => ""
]
According to the suggestions I made this change:
public function index($slug, Request $request, UserPasswordEncoderInterface $passwordEncoder)
{
$page = $this->getDoctrine()->getManager()->getRepository(Pages::class)->findOneBy(['slug'=>$slug]);
$fields = get_object_vars($page);
return $this->render('mypage.html.twig', ['page' => $page, 'fields' => $fields]);
}
But this outputs me an empty array.

You have two options:
1. Use Query::HYDRATE_ARRAY instead of findOneBy()
$query = $this->getDoctrine()
->getRepository(Pages:class)
->createQueryBuilder('p')
->getQuery();
$result = $query->getResult(Query::HYDRATE_ARRAY);
(stolen from this answer)
2. Use a Serializer
Use the Serializer Component or JMSSerializerBundle to serialize your entity object.
