Php 合并2个没有重复键的数组

我有如下两个数组，希望将它们合并在一起，而不是将密钥复制到新数组中

$array1：

Array
(
[0] => Array
    (
        [a] => Array
            (
                [p] => Array
                    (
                        [a] => 1
                    )

            )

        [a/s] => Array
            (
                [p] => Array
                    (
                        [o] => 1
                    )

            )

        [a/p] => Array
            (
                [p] => Array
                    (
                        [w] => 1
                        [e] => 1
                        [d] => 1
                    )

            )

        [a/u] => Array
            (
                [p] => Array
                    (
                        [w] => 1
                        [e_a] => 1
                        [d_a] => 1
                    )
            )
    )
)

$array2：

Array
(
[0] => Array
    (
        [a/x] => Array
            (
                [p] => Array
                    (
                        [a] => 1
                    )

            )

        [a/s] => Array
            (
                [p] => Array
                    (
                        [o] => 1
                    )

            )

        [a/p] => Array
            (
                [p] => Array
                    (
                        [w] => 1
                        [e] => 1
                        [d] => 1
                    )

            )

        [a/u] => Array
            (
                [p] => Array
                    (
                        [w] => 1
                        [e_a] => 1
                        [d_a] => 1
                    )
            )
    )
)


$result = array_merge_recursive($array1, $array2);

$result:

Array
(
[0] => Array
    (
        [a] => Array
            (
                [p] => Array
                    (
                        [a] => 1
                    )
            )

        [a/s] => Array
            (
                [p] => Array
                    (
                        [o] => Array
                            (
                                [0] => 1
                                [1] => 1
                            )
                    )
            )

        [a/p] => Array
            (
                [p] => Array
                    (
                        [w] => Array
                            (
                                [0] => 1
                                [1] => 1
                            )

                        [e] => Array
                            (
                                [0] => 1
                                [1] => 1
                            )

                        [d] => Array
                            (
                                [0] => 1
                                [1] => 1
                            )
                    )
            )

        [a/u] => Array
            (
                [p] => Array
                    (
                        [w] => Array
                            (
                                [0] => 1
                                [1] => 1
                            )

                        [e_a] => Array
                            (
                                [0] => 1
                                [1] => 1
                            )

                        [d_a] => Array
                            (
                                [0] => 1
                                [1] => 1
                            )
                    )
            )

        [a/x] => Array
            (
                [p] => Array
                    (
                        [a] => 1
                    )
            )
    )
)

我该如何让它看起来像这样

Array
(
[0] => Array
    (
        [a] => Array
            (
                [p] => Array
                    (
                        [a] => 1
                    )

            )

        [a/s] => Array
            (
                [p] => Array
                    (
                        [o] => 1

                    )

            )

        [a/p] => Array
            (
                [p] => Array
                    (
                        [w] => 1
                        [e] => 1
                        [d] => 1
                    )

            )

        [a/u] => Array
            (
                [p] => Array
                    (
                        [w] => 1
                        [e_a] => 1
                        [d_a] => 1
                    )
            )

        [a/x] => Array
            (
                [p] => 1
            )
    )
)

我是不是走错了路，还是有什么办法可以解决这个问题？欢迎举例

您是否尝试过

数组\u合并

页面中的用户自定义示例/函数？

似乎有相当多的例子符合你的要求。保留键（无需重新编号）的一个建议是使用

+

操作符

$result=$x1+$x2

（其中x是数组）

function array_merge_recursive_unique($array1, $array2) {
  if (empty($array1)) return $array2; //optimize the base case

  foreach ($array2 as $key => $value) {
    if (is_array($value) && is_array(@$array1[$key])) {
      $value = array_merge_recursive_unique($array1[$key], $value);
    }
    $array1[$key] = $value;
  }
  return $array1;
}
