Supporse you array is named $data

    foreach($data as &$array){
        $array["total_weight"] = array_sum(array_column($array,"weight"));
    }

+1, but might be helpful to include the conversion to a native array, as this will fail on what OP describes as their 'array' (which is literally a JSON string).

try with laravel collection collect() then you can use ->sum() function

foreach ($data as $key => $item) {
    $temp = collect($item);
    $data[$key]['total_weight'] = $temp->sum('weight');
}
return $data;
