PHP数组将值从一个数组合并到另一个数组

PHP array merge values from one array into another

很抱歉，我读了这么多的文章来理解这一点，最终弄糊涂了自己！

我有两个数组：

数组1：

1
2
3
4
5
6
7
8
9

Array (

[0] => Array ( [ID] => SI012348 [Date] => 06/01/2016 [Month] => 1 [Tier1] => 2.188875 [Tier2] => [Tier3] => [Tier4] => [Delivery] => 0 )

[1] => Array ( [ID] => SI012351 [Date] => 06/01/2016 [Month] => 1 [Tier1] => 2.139 [Tier2] => 0 [Tier3] => 0 [Tier4] => 0 [Delivery] => 0 )

[2] => Array ( [ID] => SI012387 [Date] => 14/01/2016 [Month] => 1 [Tier1] => 0.201 [Tier2] => 0 [Tier3] => 0 [Tier4] => 0 [Delivery] => 0 )

)

数组2：(包含所有带交货费用的发票)

1
2
3
4
5
6
7
8

Array (
[SI000005] => 25
[SI000010] => 15
[SI000054] => 20
[SI000069] => 0
[SI000074] => 20
[SI000076] => 16
)

我需要更新si00000x匹配的数组1，并将数组2中的值推送到数组1中的[传递]值中。

我相信这很简单，但我所做的每件事都需要一个年龄或者崩溃！

请帮助！

您可以使用这个(注意和号)：

1
2
3

foreach ($arr1 as &$rec) {
if (isset($arr2[$rec['ID']])) $rec['Delivery'] = $arr2[$rec['ID']];
}
