Doctrine 2 findAll returns just 1 result - php

Question

The findAll() finds one result in my repository:
$retorno[] = $bd->getEntityManager()->getRepository($classname)->findAll();
Class of entity:
<?php
use Doctrine\ORM\Mapping as ORM;
/**
* Subtipo
*
* #ORM\Table(name="subtipo", indexes={#ORM\Index(name="fk_Subtipo_Tipo1_idx", columns={"Tipo_id"})})
* #ORM\Entity
*/
class Subtipo
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer", nullable=false)
* #ORM\Id
* #ORM\GeneratedValue(strategy="IDENTITY")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="nome", type="string", length=45, nullable=false)
*/
private $nome;
/**
* #var \Tipo
*
* #ORM\ManyToOne(targetEntity="Tipo")
* #ORM\JoinColumns({
* #ORM\JoinColumn(name="Tipo_id", referencedColumnName="id")
* })
*/
private $tipo;
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set nome
*
* #param string $nome
*
* #return Subtipo
*/
public function setNome($nome)
{
$this->nome = $nome;
return $this;
}
/**
* Get nome
*
* #return string
*/
public function getNome()
{
return $this->nome;
}
/**
* Set tipo
*
* #param \Tipo $tipo
*
* #return Subtipo
*/
public function setTipo(\Tipo $tipo = null)
{
$this->tipo = $tipo;
return $this;
}
/**
* Get tipo
*
* #return \Tipo
*/
public function getTipo()
{
return $this->tipo;
}
}
Somebody can help?

If you do this
$retorno[] = $bd->getEntityManager()->getRepository($classname)->findAll();
^----- this
You're creating an array of arrays (or array of ArrayCollection) so, if you inspect length of $retorno[] this will result in 1 element that will contain real results.
Something like
$retorno = [
0 => [
0 => 'first real result',
1 => 'second real result',
[...]
n => 'nth real result'
]
];
Just use this syntax
$retorno = $bd->getEntityManager()->getRepository($classname)->findAll();
