getResult() method Doctrine - symfony

Question

What is the format of the array returned using the getResult() method in the following example, using Doctrine and Symfony2:
$query = $this->_em->createQuery('SELECT p.id, p.nameProduct FROM ArkiglassProductBundle:Product p');
return $query->getResult();
And I would like to know how to access each case and print every row.

Answer 1

<?php
$query = $em->createQuery('SELECT u.username, u.name FROM CmsUser u');
$users = $query->getResults(); // array of CmsUser username and name values
echo $users[0]['username'];
taken from the doctrine documentation

Answer 2

Are you asking about "0" in $users[0]?
I hope I am not misunderstanding your question.
getResults() returns an array of database results. Once you've given your array a name you can access each element using the index.
Of course if you want to loop over it you will probably use a foreach loop so you won't have to use the index:
$products = $query->getResults();
foreach ($products as $product){
echo $product->id.' '.$product->nameProduct;
}
This said... this pseudo code is here for the sake of explanation. If you are using Symfony you will have to display your results in a view file, probably using twig like Manuszep did in his example.
In his case you will have to use a for in loop like he did.

Answer 3

The query returns an array of Users:
array(
0 => array(username => 'aaa', name => 'bbb'),
1 => array(username => 'ccc', name => 'ddd')
)
So the $users[0] element means the first user in the list.
You can use a for loop to iterate:
{% for user in users %}
{{ user.username }} - {{ user.name }}
{% endfor %}
