Question

我是新手，将数组合并到多维数组有问题。我已经使用array_merge进行了测试，但工作正常。

我有这样的数组：

Array (
    [0] => value 1
    [1] => value 2
    [2] => value 3
    [3] => value 4
)

像这样的多维数组：

Array
(
    [0] => Array
        (
            [name] => simple
            [label] => Simple
            [filter] => 1
            [filterexcerpt] => 1
        )

    [1] => Array
        (
            [name] => compleks
            [label] => Compleks
            [filter] => 1
            [filterexcerpt] => 1
        )

    [2] => Array
        (
            [name] => standard
            [label] => Standard
            [filter] => 
            [filterexcerpt] => 
        )

    [3] => Array
        (
            [name] => abstract
            [label] => Abstract
            [filter] => 1
            [filterexcerpt] => 1
        )
)

如何将数组合并到多维数组，以及我想要的结果：

Array
(
    [0] => Array
        (
            [name] => simple
            [label] => Simple
            [filter] => 1
            [filterexcerpt] => 1
            [value] => value 1
        )

    [1] => Array
        (
            [name] => compleks
            [label] => Compleks
            [filter] => 1
            [filterexcerpt] => 1
            [value] => value 2
        )

    [2] => Array
        (
            [name] => standard
            [label] => Standard
            [filter] => 
            [filterexcerpt] => 
            [value] => value 3
        )

    [3] => Array
        (
            [name] => abstract
            [label] => Abstract
            [filter] => 1
            [filterexcerpt] => 1
            [value] => value 4
        )
)

请帮忙。

循环小数组，并将其值放入更大的数组中，两个数组的索引都匹配。

foreach ($small_array as $key=>$value) {
    $multidimensional_array[$key]['value'] = $value);
}

更改代码中显示的$small_array和$multidimensional_array。

上面的代码片段没有检查多维数组实际上是否有这样的索引，与小数组中的索引匹配。您可以在添加之前添加array_key_exist()或isset()支票，以使代码更加万无一失。
