php中的多維數組（具有相同的鍵不同的值）如何為鍵創建新名稱？

Question

我目前有一個帶有兩個子數組的多維數組。 數據庫的構建方式給了我這個結果。 我想要做的是創建一個帶有提交 ID 的新數組，並將其他值合並在一起。 唯一的問題是值是相同的鍵但不是值。

(
    [0] => Array
        (
            [sub_field_id] => 123
            [submission_id] => 8
            [field_id] => 81
            [form_id] => 9
            [value] => Male
        )

    [1] => Array
        (
            [sub_field_id] => 130
            [submission_id] => 8
            [field_id] => 92
            [form_id] => 9
            [value] => N4 Mar 27 theory Apr 20-23 onbike
        )
) 

我嘗試使用 foreach 創建一個新數組

    $this_submission = $sub_array['submission_id'];
    $submission_keys[$this_submission][$result] = array('value'=> $sub_array['value']);
  }

But the results don't help
[8] => Array
        (
            [0] => Array
                (
                    [value] => Male
                )

            [1] => Array
                (
                    [value] => N4 Mar 27 theory Apr 20-23 onbike
                )

        )

我想得到的是以下內容：

[8] => Array
        (
            [0] => Array
                (
                    [gender] => Male,
                    [date] => N4 Mar 27 theory Apr 20-23 onbike
                )
        )

這可能嗎？

如果您在上面顯示的模式中擁有所有數組，則此代碼有效。 工作解決方案演示

$arr = [
    [
        "sub_field_id" => "123",
        "submission_id" => "8",
        "field_id" => "81",
        "form_id" => "9",
        "value" => "Male",
    ],
    [
        "sub_field_id" => "123",
        "submission_id" => "8",
        "field_id" => "81",
        "form_id" => "9",
        "value" => "N4 Mar 27 theory Apr 20-23 onbike",
    ]   
];

$res_arr = [];
$arr_count = count($arr);
foreach($arr as $key=>$val){

    if($key < $arr_count-1){

        //here I am getting the last value from the current array and the next array.
        //so if you know the key names you can get the value as $val = $arr[$key]['key_name'];
        $end_val1 = end($arr[$key]);
        $end_val2 = end($arr[$key+1]);

        $temp = array_merge($arr[$key], $arr[$key+1]);
        array_pop($temp);
        array_values($temp);
        $temp['gender'] = $end_val1;
        $temp['date'] = $end_val2;

        $res_arr[] = $temp;
    }
}

print_r($res_arr);

輸出：

Array
(
[0] => Array
    (
        [sub_field_id] => 123
        [submission_id] => 8
        [field_id] => 81
        [form_id] => 9
        [gender] => Male
        [date] => N4 Mar 27 theory Apr 20-23 onbike
    )

)
