Question

我删除空数组时遇到问题。我的数组看起来像：

canvas

最后一个孩子总是有两把钥匙（仓库和价格）

我的代码：

Array
(
    [Women] => Array
        (
            [S] => Array
                (
                    [warehouse] => 22
                    [price] => 21212
                )

            [M] => Array
                (
                    [warehouse] => 
                    [price] => 
                )

            [L] => Array
                (
                    [warehouse] => 
                    [price] => 
                )

            [XL] => Array
                (
                    [warehouse] => 
                    [price] => 
                )

            [XXL] => Array
                (
                    [warehouse] => 
                    [price] => 
                )

        )
    [Men] => Array
        (
            [S] => Array
                (
                    [warehouse] => 22
                    [price] => 
                )

            [M] => Array
                (
                    [warehouse] => 
                    [price] => 
                )

            [L] => Array
                (
                    [warehouse] => 
                    [price] => 
                )

            [XL] => Array
                (
                    [warehouse] => 
                    [price] => 
                )

            [XXL] => Array
                (
                    [warehouse] => 
                    [price] => 
                )

        )
)

结果：

$value = $this->$attribute;   
$check = function($haystack) use(&$check)
{
    foreach ($haystack as $key => $value) {
        if (is_array($value)) {
            $haystack[$key] = $check($haystack[$key]);
        }

        if (empty($haystack[$key])) {
            unset($haystack[$key]);
        }
    }

    return $haystack;
};

var_dump(  $check($value) );

它的工作但我的问题是应该删除'Men数组'，因为最后一级只有仓库密钥（正确的两个密钥）。如何改变我的功能以获得我想要的结果？

如果$ array包含这个``

strtok

然后迭代每个数组键女人，男人在每个键中我们将迭代到s，m，l，xl如果任何奖项缺少元素我们将取消它，并在最后迭代我们将检查女性和男性的大小，如果其中一个没有大小，那么我们将取消设置性别密钥。

Array
(
    [Women] => Array
        (
            [S] => Array
                (
                    [warehouse] => 22
                    [price] => 21212
                )
        [M] => Array
            (
                [warehouse] => 
                [price] => 
            )

        [L] => Array
            (
                [warehouse] => 
                [price] => 
            )

        [XL] => Array
            (
                [warehouse] => 
                [price] => 
            )

        [XXL] => Array
            (
                [warehouse] => 
                [price] => 
            )

    )
[Men] => Array
    (
        [S] => Array
            (
                [warehouse] => 22
                [price] => 
            )

        [M] => Array
            (
                [warehouse] => 
                [price] => 
            )

        [L] => Array
            (
                [warehouse] => 
                [price] => 
            )

        [XL] => Array
            (
                [warehouse] => 
                [price] => 
            )

        [XXL] => Array
            (
                [warehouse] => 
                [price] => 
            )
      )
)

使用一些规则删除数组的空元素
