php - 在php中组合多维数组

Question

我在尝试什么

我有 2 个数组，如下所示:

数组 1:

Array
(
 [38] => Array
    (
        [0] => Array
            (
                [code] => ACC
                [amount] => 50
                [emp_number] => 38
            )

        [1] => Array
            (
                [code] => CAR
                [amount] => 60
                [emp_number] => 38
            )

    )

[22] => Array
    (
        [0] => Array
            (
                [code] => ACC
                [amount] => 110
                [emp_number] => 22
            )

        [1] => Array
            (
                [code] => AIR
                [amount] => 260
                [emp_number] => 22
            )

        [2] => Array
            (
                [code] => CAP
                [amount] => 205
                [emp_number] => 22
            )
      )

 )

数组 2:

 Array
(
[0] => Array
    (
        [code] => ACC
    )

[1] => Array
    (
        [code] => AIR
    )

[2] => Array
    (
        [code] => ARC
    )

[3] => Array
    (
        [code] => ATV
    )

[4] => Array
    (
        [code] => CAP
    )

[5] => Array
    (
        [code] => CAR
    )

)

我想要什么

最终数组:

   Array
(
 [38] => Array
    (
        [0] => Array
            (
                [code] => ACC
                [amount] => 50
                [emp_number] => 38
            )

        [1] => Array
            (
                [code] => AIR
                [amount] => ''
                [emp_number] => 38
            )
        [2] => Array
            (
                [code] => ARC
                [amount] => ''
                [emp_number] => 38
            )

        [3] => Array
            (
                [code] => ATV
                [amount] => ''
                [emp_number] => 38
            )

        [4] => Array
            (
                [code] => CAP
                [amount] => ''
                [emp_number] => 38
            )

        [5] => Array
            (
                [code] => CAR
                [amount] => 60
                [emp_number] => 38
            )

    )

[22] => Array
    (
        [0] => Array
            (
                [code] => ACC
                [amount] => 110
                [emp_number] => 22
            )

        [1] => Array
            (
                [code] => AIR
                [amount] => 260
                [emp_number] => 22
            )
        [2] => Array
            (
                [code] => ARC
                [amount] => ''
                [emp_number] => 22
            )

        [3] => Array
            (
                [code] => ATV
                [amount] => ''
                [emp_number] => 22
            )

        [4] => Array
            (
                [code] => CAP
                [amount] => 205
                [emp_number] => 22
            )

        [5] => Array
            (
                [code] => CAR
                [amount] => ''
                [emp_number] => 22
            )
      )

 )

代码

 $count = count($category);
    $exp = array();
    foreach ($expItem as $empItem) {
        $j = 0;
        foreach ($category as $cat) {
            foreach ($empItem as $emp) {
                for ($k = 0; $k < $count; $k++) {
                    if ($emp['code'] == $category['code']) {
                        $expItem[$emp['emp_number']][$k]['name'] = $category[$k]['name'];
                    } else {
                        $expItem[$emp['emp_number']][$k]['code'] = $category[$k]['code'];
                        $expItem[$emp['emp_number']][$k]['name'] = $category[$k]['name'];
                    }
                }
            }
            $j++;
        }
    }

此处 $expItem 是第一个数组，$category 是第二个数组，我在 $expItem 本身中获取最终数组。 $emp['emp_number'] 是第一个数组“38”和“22”的单元键。它与 code 和 amount 一起在第一个数组中可用。 $category 还包含值 name

如何组合这两个数组才能正确得到最终数组？

编辑: 第一个数组中的代码与第二个数组中的代码相同。第二个数组包含所有代码和各自的名称。第一个数组显示员工数据，其中显示员工使用的代码数量。我想要的是，如果员工没有使用任何代码，那么第一个数组应该在员工数据中显示相应的代码和金额为 0。代码是动态实现的，因此不能对其进行硬编码。

Answer 1

你能试试这个吗？ $result 将具有预期的数组。

$result = [];

foreach($expItem as $key => $item) {

    $result[$key] = array_map(function($value) use ($key, $item){
        $value['amount'] = '';
        $value['emp_number'] = $key;

        foreach($item as $_key => $_item) {
            if($_item['code'] === $value['code']) {
                $value['amount'] = $_item['amount'];
            }
        }

        return $value;

    }, $category);

}
