PHP JSON Array - Group by the same value

Question

I\'m thinking how to group my array by objects with the same value.

I have this result from MySQL query:

   Date           StartTime           EndTim         


        

Answer 1

EMPLOYER NAME DATA_PATH Alp 1. video_link 2. video_link Xyz 1. video_link 2. video_link 3. video_link

$stmt = $this->conn->prepare("SELECT a.employer_name,b.data_path FROM 
rec_experience a INNER JOIN rec_multi_upload_data b 
ON(a.rec_uniqueid=b.rec_id) WHERE b.data_type='Video'  ORDER BY 
a.c_date DESC ");
$stmt->execute();
$res = $stmt->fetchAll(PDO::FETCH_ASSOC);

$out = [];

foreach($res as $element)
{
 $out[$element['employer_name']][] = ['video_link' => 
 $element['data_path']];
}
echo json_encode($out);
