I have solved it.
public function getDateWiseScore($data) {
$groups = array();
foreach ($data as $item) {
$key = $item['evaluation_category_id'];
if (!array_key_exists($key, $groups)) {
$groups[$key] = array(
'id' => $item['evaluation_category_id'],
'score' => $item['score'],
'itemMaxPoint' => $item['itemMaxPoint'],
);
} else {
$groups[$key]['score'] = $groups[$key]['score'] + $item['score'];
$groups[$key]['itemMaxPoint'] = $groups[$key]['itemMaxPoint'] + $item['itemMaxPoint'];
}
}
return $groups;
}
