Php 将数组与现有数组合并
我有两个数组，都包含数据。我希望能够将它们添加到一起，以便来自第二个数组的信息连接到第一个数组中。目前，我正在进行的数组合并将第二个数组添加到第一个数组的末尾 阵列1Php 将数组与现有数组合并,php,arrays,array-merge,Php,Arrays,Array Merge,我有两个数组，都包含数据。我希望能够将它们添加到一起，以便来自第二个数组的信息连接到第一个数组中。目前，我正在进行的数组合并将第二个数组添加到第一个数组的末尾 阵列1 [1] => Array ( [0] => 2017-07-13 00:00:00 [1] => Foo [2] => Bar [3] => 16.11 [4] =&

array\u merge（$array1，$array2）这让我非常期待，您只需array\u merge（）
这两个数组的元素：
Array
(
[1] => Array
(
[0] => 2017-07-13 00:00:00
[1] => Foo
[2] => Bar
[3] => 16.11

[6] => TIME
[7] => Lorem
[8] => Ipsum
)
[2] => Array

[2] => Bar
[3] => 1.23
[4] => 50.69
[5] => 14.24
[6] => TIME
[7] => Some
[8] => Text
)
)
更新：
在下面的评论中，您询问是否可以将此方法推广到合并任意数量的数组。确保这是可能的，您只需添加另一个迭代层：
Array
(
[1] => Array
(
[0] => 2017-07-13 00:00:00
[1] => Foo
[2] => Bar
[3] => 16.11
[4] => 80.56
[5] => 96.67
[6] => TIME
[7] => Lorem
[8] => Ipsum
[9] => C1a
[10] => C1b
)
[2] => Array
(
[0] => 2017-07-13 00:00:00
[1] => Foo
[2] => Bar
[3] => 1.23
[4] => 50.69
[5] => 14.24
[6] => TIME
[7] => Some
[8] => Text
[9] => C2a
[10] => C2b
[11] => C2b
)
)
是否要创建多维数组
那很容易
$array1 = [
[1,2,3,4],
[6,7,8,9]
];
$array2 = [
['a','b'],
['c', 'd']
];
$array3 = [];
foreach (range(0, max(count($array1), count($array2))-1) as $i) {
$part1 = isset($array1[$i]) ? $array1[$i] : [];
$part2 = isset($array2[$i]) ? $array2[$i] : [];
$array3[] = array_merge($part1, $part2);
}
您可以尝试以下方法：
每个数组中有2个数组，所以将每个数组与其对应的数组合并，而不是主数组。您尝试过吗？请尝试您自己的代码。您将看到，它不会产生问题中所述的输出。您是对的，我先发制人，没有完成问题。我尝试了这个方法，但没有成功，请参阅编辑的问题，了解我使用array\u merge（）和array\u merge\u recursive（）Genius获得的输出。如果我有两个以上的阵列，这是否适用？如果我想将3个数组合并成一个？当然，我添加了一个变量作为答案的更新。
