Doctrine 2 Query returns class description? - php

Question

I have a small simple symfony 6.1.4 application and wanted to write a API for a few Entities, but when i fetch the data from the database (mysql) i get something what looks like a class description.
$test = $this->audienceRepository->createQueryBuilder('s')->getQuery()->getResult();
var_dump($test);
Entity
<?php
namespace App\Entity;
use App\Repository\AudienceRepository;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;
#[ORM\Entity(repositoryClass: AudienceRepository::class)]
class Audience
{
#[ORM\Id]
#[ORM\GeneratedValue]
#[ORM\Column]
private ?int $id = null;
#[ORM\Column(length: 255)]
private ?string $name = null;
#[ORM\Column]
private ?bool $is_department = null;
#[ORM\Column]
private ?bool $is_company = null;
#[ORM\OneToMany(mappedBy: 'department', targetEntity: User::class)]
private Collection $users;
#[ORM\ManyToMany(targetEntity: Seminar::class, mappedBy: 'audience')]
private Collection $seminars;
public function __construct()
{
$this->users = new ArrayCollection();
$this->seminars = new ArrayCollection();
}
public function getId(): ?int
{
return $this->id;
}
public function getName(): ?string
{
return $this->name;
}
public function setName(string $name): self
{
$this->name = $name;
return $this;
}
public function isIsDepartment(): ?bool
{
return $this->is_department;
}
public function setIsDepartment(bool $is_department): self
{
$this->is_department = $is_department;
return $this;
}
public function isIsCompany(): ?bool
{
return $this->is_company;
}
public function setIsCompany(bool $is_company): self
{
$this->is_company = $is_company;
return $this;
}
/**
* #return Collection<int, User>
*/
public function getUsers(): Collection
{
return $this->users;
}
public function addUser(User $user): self
{
if (!$this->users->contains($user)) {
$this->users->add($user);
$user->setDepartment($this);
}
return $this;
}
public function removeUser(User $user): self
{
if ($this->users->removeElement($user)) {
// set the owning side to null (unless already changed)
if ($user->getDepartment() === $this) {
$user->setDepartment(null);
}
}
return $this;
}
/**
* #return Collection<int, Seminar>
*/
public function getSeminars(): Collection
{
return $this->seminars;
}
public function addSeminar(Seminar $seminar): self
{
if (!$this->seminars->contains($seminar)) {
$this->seminars->add($seminar);
$seminar->addAudience($this);
}
return $this;
}
public function removeSeminar(Seminar $seminar): self
{
if ($this->seminars->removeElement($seminar)) {
$seminar->removeAudience($this);
}
return $this;
}
}
Repository
namespace App\Repository;
use App\Entity\Audience;
use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;
use Doctrine\Persistence\ManagerRegistry;
/**
* #extends ServiceEntityRepository<Audience>
*
* #method Audience|null find($id, $lockMode = null, $lockVersion = null)
* #method Audience|null findOneBy(array $criteria, array $orderBy = null)
* #method Audience[] findAll()
* #method Audience[] findBy(array $criteria, array $orderBy = null, $limit =null, $offset = null)
*/
class AudienceRepository extends ServiceEntityRepository {
public function __construct(ManagerRegistry $registry)
{
parent::__construct($registry, Audience::class);
}
public function add(Audience $entity, bool $flush = false): void
{
$this->getEntityManager()->persist($entity);
if ($flush) {
$this->getEntityManager()->flush();
}
}
public function remove(Audience $entity, bool $flush = false): void
{
$this->getEntityManager()->remove($entity);
if ($flush) {
$this->getEntityManager()->flush();
}
}
result of var_dumb
I couldnt find why doctrine is behaving this way. Does someone know why and how to prevent that?

Answer 1

Everything is correct as the doctrine returns to you Objects of your ENTITY filled with data from the DB
You get Each row as a separate class and can use it as follows
<?php
foreach($results as $audience) {
$audience->getId();
}
Doctrine return to you list object with set data in Entity: Example
<?php
class Audience
{
#[ORM\Id]
#[ORM\GeneratedValue]
#[ORM\Column]
private ?int $id = 12;
#[ORM\Column(length: 255)]
private ?string $name = "You name from DB";
#[ORM\Column]
private ?bool $is_department = true;
#[ORM\Column]
private ?bool $is_company = true;
#[ORM\OneToMany(mappedBy: 'department', targetEntity: User::class)]
private Collection $users = new Collection(<With Users objects>);;
#[ORM\ManyToMany(targetEntity: Seminar::class, mappedBy: 'audience')]
private Collection $seminars = new Collection(<With Seminars objects>);
