Loop json in twig - json

Question

This is my controller where I am creating json data and passing it to twig file:
/**
*this route is for inserting data into datatable of modal of bootstrap
* #Route("/pagerduty/edit_team_datatable")
* #return Response
*/
public function edit_teble(Request $request){
$edit = new team_details();
$row_id = $request->query->get('row_id');
$query= ("SELECT tr.id, GROUP_CONCAT(u.usrName SEPARATOR ',') AS team_members FROM team_details td
INNER JOIN team_registration tr ON tr.id=td.team_name
INNER JOIN user u ON u.usrid=td.team_members_names
WHERE td.team_name=$row_id
GROUP BY td.team_name");
$em = $this->getDoctrine()->getManager();
$statement = $em->getConnection()->prepare($query);
$statement->execute();
$result = $statement->fetch();
// print_r($result);die;
//return $this->render("team_display.html.twig",array('edit_table'=>$result));
return new JsonResponse($result);
}
I am receiving json response in this manner where id is only "1" and team_members is "8". So now, I want to create 8 id for 8 team members.
This is json data:
{"id":"21","team_members":"teja,preetham,kick,preetham,teja,meuser,kick,preetham"}
What I need is this format using looping:
{"id":"21,21,21,21,21,21,21,21","team_members":"teja,preetham,kick,preetham,teja,meuser,kick,preetham"}

As #Marc_Andre mentioned in the comment above, you should manipulate your data in the controller instead of in the template.
Based on the format of your query result, you can do the following in the controller:
$formatted = [];
$id = $result['id'];
foreach ($result['team_members'] as $member) {
$formatted[] = [$id => $member];
}
return new JsonResponse($formatted);
