Symfony DQL - transform the array query result - sql

Question

I'm trying to transform the array of my query result.
First I did this query:
public function findAllTraduction()
{
return $this->createQueryBuilder('c')
->select('c.key, c.content, c.id, f.locale')
->leftJoin('c.TraductionFile', 'f')
->groupBy('c.key')
->getQuery()
->getArrayResult();
}
The result is like that:
array
0 =>
array
'key' => string 'FORMAT1'
'content' => string 'login'
'id' => int 507
'locale' => string 'en'
1 =>
array
'key' => string 'FORMAT1'
'content' => string 'connecter'
'id' => int 508
'locale' => string 'fr'
2 =>
array
'key' => string 'FORMAT2'
'content' => string 'password'
'id' => int 503
'locale' => string 'en'
3 =>
array
'key' => string 'FORMAT2'
'content' => string 'mot de passe'
'id' => int 504
'locale' => string 'fr'
What I would like to have is an array like that:
array
'FORMAT1' =>
array
'en' =>
array
'content' => string 'login'
'id' => int 507
'fr' =>
array
'content' => string 'connecter'
'id' => int 508
'FORMAT2' =>
array
'en' =>
array
'content' => string 'password'
'id' => int 503
'fr' =>
array
'content' => string 'mot de passe'
'id' => int 504
In fact, for each same 'key' (here 'FORMAT1' and 'FORMAT2', regroup by 'locale' (EN and FR)
Is it possible to do that in the query ?
I tried with GROUPBY and DISTINCT but nothing happened...
If not possible in query, may be redraw an array with loop....
thank you !

Answer 1

Doctrine provides a way to specify indexBy when creating the QueryBuilder in order to index the resulting array not in a sequential way but by a specific key :
createQueryBuilder($alias, $indexBy = null)
So you may want to try something like createQueryBuilder('c', 'c.key') to use c keys as array indexes

Answer 2

I found a solution with foreach for redraw the array ...
$catalogue = [];
foreach ($catalogues_array as $index => $val) {
$key = $val['key'];
$locale = $val['locale'];
unset($catalogues_array[$index]['key']);
unset($catalogues_array[$index]['locale']);
$catalogue[$key][$locale] = $catalogues_array[$index];
}
return $catalogue;
the result :
array (size=421)
'base_template.page_title' =>
array (size=2)
'en' =>
array (size=6)
'content' => string 'Audio Video Caption - Subtitling & Transcription of media.' (length=58)
'description' => null
'traductionControle' => boolean false
'id' => int 1
'domain' => string 'messages' (length=8)
'bundleName' => string 'app' (length=3)
'fr' =>
array (size=6)
'content' => string 'Audio Video Caption - Sous-Titrage & Transcription de médias.' (length=62)
'description' => null
'traductionControle' => boolean false
'id' => int 9
'domain' => string 'messages' (length=8)
'bundleName' => string 'app' (length=3)
'base_template.meta.keywords' =>
array (size=2)
'en' =>
array (size=6)
'content' => string 'closed captioning, subtitle, speech recognition, transcription, traduction, video, audio' (length=88)
'description' => null
'traductionControle' => boolean false
'id' => int 2
'domain' => string 'messages' (length=8)
'bundleName' => string 'app' (length=3)
'fr' =>
array (size=6)
'content' => string 'sous-titre, reconnaissance vocale, transcription, traduction, video, audio' (length=74)
'description' => null
'traductionControle' => boolean false
'id' => int 10
'domain' => string 'messages' (length=8)
'bundleName' => string 'app' (length=3)
