PHP Mysql 对子节点求和并与父节点树累加

Question

我有一个名为

dt_account

data 的数据库表，结构或多或少像这样：

以及一个名为

dt_jurnaltransaksi

的交易表，其结构如下：

这是使用子父树查询上表的结果，这就是我的代码中发生的情况：

这就是应该的结果，也是我想要的结果，所以

total

数据也在父帐户中

这是我使用的php文件

这是代码的修改版本，它应该正确计算子节点的总和并将其添加到父节点的总和中。

function calculateTotal(&$array) {
    $total = 0;
    foreach ($array as &$arr) {
        if (isset($arr['child'])) {
            $arr['nominal_hr'] += calculateTotal($arr['child']);
        }
        $total += $arr['nominal_hr'];
    }
    return $total;
}

// Call the function on your data array
calculateTotal($data);

// Now you can build your table as before
echo build_laba($data);
