合并的多维阵列到另一个多维数组 [英] merging a multi-dimensional array into another multi-dimensional array

问题描述

这涉及到我的previous职位。
<一href=\"http://stackoverflow.com/questions/5209265/how-to-create-a-collection-of-multi-dimensional-arrays-and-not-overwrite-origiona\">how创建多维数组的集合，当新推不覆盖原始值。

this relates to my previous post. how to create a collection of multi dimensional arrays and not overwrite origional values when new ones are pushed.

我在想我的问题与我是多么创建阵列做。我想要做的是使一个数组，看起来像这样

i am thinking my problem has to do with how i am creating the array. what i'm trying to do is make an array that looks like this

Array
(
    [10] => Array
        (
           [0] => 29
           [1] => 36
        )

)

弄成这个样子

    Array
    (
        [10] => Array
            (
               [0] => 29
               [1] => 36
            )


 [20] => Array
            (
               [0] => 29
               [1] => 36
            )


 [25] => Array
            (
               [0] => 29
               [1] => 36
            )

    )

的 10，20和25是在产品id其中内的那些数字是被选择在该网页上（在我上面给出的链接）的选择。所以每个产品都将会有自己的收藏选择。

the 10, 20, and 25 is the product id where the numbers within those are the selections that were selected on that page (in the link i gave above). so each product would have its own collection selected.

当我使用array_push，而不是做什么，我想要它做数组的第一个集合作为第一个例子保持CH375复位。所以，如果我做的传单说我的选择，并添加到购物车，然后我去的名片，做我的选择，并添加到购物车阵复位，它变得像第一个例子。无论我尝试，我不能把它合并一样，我有第二个例子集合下方。我曾尝试array_merge（），array_push但那些真的不工作。

when i use array_push instead of doing what i want it to do the first collection of array as in the first example keep reseting. so if i do my selections on say flyers and add to cart then i go to business cards and do my selections and add to cart the array resets and it becomes like the first example. whatever i try i cant get it to merge below a collection like the second example that i have. i have tried array_merge(),array_push but those dont really work.

推荐答案

解决方案 -

如果您想从第二个数组的数组元素追加到第一个数组，而不是覆盖从第一个数组中的元素，而不是重新索引，使用 +阵列联合运营商：

If you want to append array elements from the second array to the first array while not overwriting the elements from the first array and not re-indexing, use the + array union operator:

$a = array(10 => array(25,26));
$b = array(22 => array(45,66));
$c = $a + $b;
print_r($c);

输出 -

Array
(
    [10] => Array
        (
            [0] => 25
            [1] => 26
        )

    [22] => Array
        (
            [0] => 45
            [1] => 66
        )
)

希望这有助于。
