在第二级阵列合并 [英] Array merge at second level

问题描述

我有两个阵列，如下图所示。我需要合并数组的内容，以便我可以得到截至去年给出的第三个数组中的结构。我已经检查array_merge但想不通这是可能的方式。任何帮助AP preciated。谢谢你。

I have two arrays as shown below. I need to merge the content of the arrays so that I can get the structure as shown in the third array at last. I have checked array_merge but can't figure out the way this is possible. Any help appreciated. Thanks.

array(
    (int) 0 => array(
        'gross_value' => '100',
        'quantity' => '1'
    ),
    (int) 1 => array(
        'gross_value' => '200',
        'quantity' => '1'
    )
)

array(
(int) 0 => array(
    'item_title_id' => '1',
    'order_id' => '4'
),
(int) 1 => array(
    'item_title_id' => '2',
    'order_id' => '4'
)
)

我应该得到一个合并的数组像这样

I should get a merged array like this

array(
(int) 0 => array(
    'gross_value' => '100',
    'quantity' => '1',
    'item_title_id' => '1',
    'order_id' => 4
),
(int) 1 => array(
    'gross_value' => '200',
    'quantity' => '1',
    'item_title_id' => '2',
    'order_id' => 4
)

）

推荐答案

使用的 array_merge_recursive ：

转换所有数字键为字符串，（做是关联数组）

Convert all numeric key to strings, (make is associative array)

$result = array_merge_recursive($ar1, $ar2);
print_r($result);
