Laravel numeric array in select results - php

Question

I'm using Lumen to set up a microservice for polling a database frequently and distribute the dataset through a wamp router to multiple clients. The database query is stored in a stored procedure, that's why i do the following in my controller:
$result = DB::select($query);
return $result;
The return gives the following dataset:
[
{
"0": "012345",
"1": "Moby Dick",
"2": "Herman Melville",
"3": "Hardcover",
"isbn": "012345",
"title": "Moby Dick",
"author": "Herman Melville",
"type": "Hardcover"
},
{
"0": "123456",
"1": "Laravel: Code Bright",
"2": "Dayle Rees",
"3": "Ebook",
"isbn": "123456",
"title": "Laravel: Code Bright",
"author": "Dayle Rees",
"type": "Ebook"
},
{
"0": "234567",
"1": "Easy Laravel 5",
"2": "W.J. Gilmore",
"3": "Ebook",
"isbn": "234567",
"title": "Easy Laravel 5",
"author": "W.J. Gilmore",
"type": "Ebook"
}
]
I want to remove the numeric key-value pairs prepending the associative key-value pairs. How can i do that?
Thanks in advance!
Edit: things I tried:
$result = DB::select($query)->get(); // Gives: Call to a member function get() on array. For obvious reasons
A dirty hack like Matei stated: Looping through the array and removing the KVP where the key is numeric. Which works, but I think the Laravel/Lumen framework offers cleaner solutions, which I am not able to find.

In config/database.php you can change 'fetch' => PDO::FETCH_CLASS, to 'fetch' => PDO::FETCH_ASSOC,
or
You can use array_reduce and array_filter like:
$result = json_decode(DB::select($query), true);
$result = array_reduce($result, function ($result, $item) {
$result[] = array_filter($result, function ($key) {
return !is_numeric($key);
}, ARRAY_FILTER_USE_KEY)
return $result;
}, array());
return json_encode($result);
NOTE: If the DB stmt is returning an array, rather than a json encoded string, then you must remove the json_decode and json_encode functions calls.
