Grouping two arrays by their values with Laravel-CodePudding

Two or 3 ids are coming in $pks as follows and I am sending these id values in sql. For example, when this for runs 3 times, total_ticket and from_user_id values will come in 3 different arrays. How can I group these 3 arrays according to from_user_id value? So I want to make it into a single array

so I want to group the 2 or 3 $props returned by the value from_user_id

 $pks = $request->input('pkids');
        
                for ($i = 0; $i < count($pks); $i  ) {
                    $pk = PK::findOrFail($pks[$i]);
                    $table_ym = date('Ym', $pk->create_time);
                    $table = 'video_' . $table_ym;
                    $props = DB::select('select sum(total_ticket) as total_ticket, from_user_id from '
                      . $table . ' where pk_id=' . $pk->prop_pk_id . ' group by from_user_id');
                    
                }

Essentially this is all you have to do:

$pks = $request->input('pkids');
$pks = array_filter(array_map('intval', $pks));  //int's above 0 only

$results = DB::select('
    SELECT
          SUM(total_ticket) AS sum_total_ticket,
          MIN(create_time) AS  min_create_time,
          from_user_id
    FROM
          '.$table.'
    WHERE pk_id IN ('.implode(',', $pks).')
    GROUP BY from_user_id');

This will return 1 row per from_user_id with the total_ticket as that "groups" sum. I also included the min create time which will be the lowest value of that group for that column. Or the first (earliest) created date.

All you have to do is retrive the results which should look like this

sum_total_ticket  min_create_time       from_user_id

    53            2022-08-20 00:00:00        1
   224            2021-08-20 00:00:00        18

Make sense.
