In my Repository class I use the following code to query:
$query = $this->getEntityManager()->createQuery("
SELECT s.term, COUNT(s.term) AS freq
FROM App\Entities\SearchTerm s
GROUP BY s.term
ORDER BY s.term ASC
");
$result = $query->getResult();
The result I get is something like:
array (size=4)
0 =>
array (size=2)
'term' => string '' (length=0)
'freq' => string '1' (length=1)
1 =>
array (size=2)
'term' => string 'foo' (length=3)
'freq' => string '1' (length=1)
2 =>
array (size=2)
'term' => string 'bar' (length=3)
'freq' => string '2' (length=1)
3 =>
array (size=2)
'term' => string 'baz' (length=3)
'freq' => string '2' (length=1)
But I would rather have an associative array as a result:
array (size=4)
'' => string '1' (length=1)
'foo' => string '1' (length=1)
'bar' => string '2' (length=1)
'baz' => string '2' (length=1)
Is this possible without an extra for-loop to build the desired array?
I know its old but today I had to do almost the same, my solution without a custom hydrator
like
$result = $query->getQuery()->getResult(\Doctrine\ORM\AbstractQuery::HYDRATE_ARRAY);
as
$resultNeeded = array_map(function($value) { return $value['freq']; }, $result);
