Partial grouping of query result - php

Question

I have a custom query in my repository that gets me results be accepting zipcodes or citynames as a value.
These values are served to an autocomplete text input.
public function findByZipOrCity($cz)
{
$qb = $this->createQueryBuilder('z');
if (substr($cz, 0, 1) == "0") {
$cz = substr($cz, 1);
$qb
->select('z')
->where($qb->expr()->orX(
$qb->expr()->like('z.city', ':czRequest'),
$qb->expr()->like('z.code', ':czRequest')
))
->andWhere('z.code <= :smaller')
->setParameter('czRequest', $cz . '%')
->setParameter('smaller', 9999);
} else {
$qb
->select('z')
->where($qb->expr()->orX(
$qb->expr()->like('z.city', ':czRequest'),
$qb->expr()->like('z.code', ':czRequest')
))
->setParameter('czRequest', $cz . '%');
}
return $qb->getQuery()->getArrayResult();
}
I work with this ArrayResult() to output JSON that the autosuggest plgin accepts:
$zipcodes = $this->getDoctrine()->getManager()->getRepository("AppBundle:Zip")->findByZipOrCity($zip);
$response = new JsonResponse();
$codes = array();
foreach ($zipcodes as $zipcode) {
$codes[] = array(
'id' => $zipcode['id'],
'country' => $zipcode['country'],
'city' => $zipcode['city'],
'code' => sprintf('%05d', $zipcode['code']),
);
}
$response->setData($codes);
return $response;
so querying for 'berli' gives the above result, the autosuggest looks like this:
This works fine, now I want to alter (any of the) function to have it displayed like this:
Which of the functions do I have to change? Can I group the query already (I need one valid zip though) or just do 'something' with the array afterwards?
Any hint highly appreciated!

Answer 1

You can change in array like follow:
foreach ($zipcodes as $zipcode) {
$codes[$zipcode['id']] = array(
'id' => $zipcode['id'],
'country' => $zipcode['country'],
'city' => $zipcode['city'],
'code' => sprintf('%05d', $zipcode['code']),
);
}
