如何使用其他数组中的键对数组中的值求和[关闭]

I have an object with two arrays in JSON file :

"Data": {
        "Server": ["a", "a", "a", "a", "b", "b", "b", "b", "c", "c", "c", "c"],
        "Count": ["12", "32", "7", "1", "67", "2", "3", "6", "5", "6", "5", "4"]
    }

what I want to achive is to add all values of array 'count' for relative values in 'server' array and create new array with structure like this:

 "Data": {
            "Server": ["a", "b", "c"],
            "Count": ["52", "78", "20"]
        }

Can anyone help with this?

    One way would be to do something like this:

    <?php
    
    $object = json_decode("your json here");
    $server = $object->Server;
    $count = $object->Count;
    
    $tmp = [];
    
    for( $i = 0; $i < $server; $i++){
        $tmp[$server[$i]] += $count[$i];
    }
    
    $data = new stdClass();
    $data->Server = array_keys($tmp);
    $data->Count = array_values($tmp);
    
    $json = json_encode($data);
    

    But personally I would rather build a structure like:

    {
        "Data": {
            "Servers": {
                "a":52,
                "b":78,
                "c":20
            }
        }
    }
