How to separately implode data, based on ID or unique NAME? - laravel

Question

I have database like this
id
name
numbers
1
Kathy
5
2
Kathy
15
3
Kathy
25
4
William
5
5
William
10
and I'm trying to retrieve and save it like this
id
name
numbers
1
Kathy
5.15.25
2
William
5.10
So I made a code like this to implode and save the data
$arr_name = [];
$arr_numbers = [];
$arr_implode = [];
$data= MyDatabase::all();
foreach ($data as $data) {
if ($data->name == $data->name) {
$arr_numbers [] = $data->numbers;
} else {
$arr_numbers [] = $data->numbers;
}
$arr_implode[$data->name] = implode('.', $arr_numbers);
}
but what I get when I use dd($arr_implode); is like this, so I haven't tried saving the data in my database.
array:2 [▼
"Kathy" => "5.15.25"
"William" => "5.15.25.5.10"
]
What should I do to get the desired output? sorry, I'm not really good at arrays and stuff

You can use DB::raw to format them during the query
e.i.
use Illuminate\Support\Facades\DB;
return DB::table('table_name')->select([
DB::raw('ROW_NUMBER() OVER( ORDER BY name ) as id'),
'name',
DB::raw('group_concat(numbers SEPARATOR ".") as numbers')
])->groupBy('name')->get();
OR
Just query all the data and format the Collection
e.i.
use Illuminate\Support\Facades\DB;
$data = DB::table('table_name')->select(['id','name','numbers'])->get();
or if you have a model for that table
$data = Model::select(['id','name','numbers'])->get();
then format it the way you want
return $data
->groupBy('name')
->values()
->map( fn ( $item, $key) => [
'id' => $key+ 1,
'name' => data_get($item, '0.name'),
'numbers' => implode('.', $item->pluck('numbers')->all() )
]);
