PHP合并2阵列成一个关联数组 [英] php merge 2 arrays into one associative array

问题描述

使用PHP，我需要2个数组合并（长度相等为一个关联数组），这里是从我的当前数据集的摘录：

Using PHP I need to merge 2 arrays (of equal length into one associative array) here is an excerpt from my current data set:

[1] => Array
    (
        [0] => C28
        [1] => C29
    )

[2] => Array
    (
        [0] => 1AB010050093
        [1] => 1AB008140029
    )

这两个元素[1] [2]实际上很多不仅仅是2子元素更长（就像我说的，这是一个节选）。

both elements [1] and [2] are actually a lot longer than just 2 sub-elements (like I said, this is an excerpt).

该协议是，C28在第一阵列中对应于1AB010050093第二阵列，等等...我需要的结果是创建一个新的关联数组，看起来像这样：

The deal is that "C28" in the first array corresponds to "1AB010050093" in the second array, and so on... The result I need is to create a new associative array that looks like this:

[1] => Array    
    (
        ['ref']  => C28
        ['part'] => 1AB010050093
    )
[2] => Array
    (
        ['ref'] => C29
        ['part'] => 1AB008140029
    )

等等...

推荐答案

如果你愿意与一个数组结构，这样的妥协：

If you are willing to compromise with an array structure like this:

array(
    'C28' => '1AB010050093',
    'C29' => '1AB008140029'
);

然后就可以使用 array_combine（） （ codePAD演示）：

array_combine($refNumbers, $partIds);

否则，你需要使用foreach（ codePAD演示）：

$combined = array();

foreach($refNumbers as $index => $refNumber) {
    if(!array_key_exists($index, $partIds)) {
        throw OutOfBoundsException();
    }

    $combined[] = array(
        'ref'  => $refNumber,
        'part' => $partIds[$index]
    );
}
