返回key包含此字符串的值

I have an array like this:

我有一个像这样的数组:

array(
    [root_1] => array(
        [level_1] => array(
            [id_1] => array(
                [foo] = bar
            )
        )
    )
)

Where I know the names (i.e root, level and id) but I do not know the number part of the key.

我知道名称(即根,级别和ID),但我不知道密钥的数字部分。

I need a function that can return any parts of the array where the key contains a given name.

我需要一个函数,可以返回键包含给定名称的数组的任何部分。

Cheers

Here you go

干得好

function search_incomplete ($needle, $haystack)
{
    foreach (new RecursiveIteratorIterator (new RecursiveArrayIterator ($haystack), RecursiveIteratorIterator::SELF_FIRST) as $key => $value)
    {
        if (strpos ($key, $needle) === 0)
        {
            return $value;
        }
    }
}

$array = array (
    'root_1'    => array (
        'level_1'   => array (
            'foo'   => 'bar',
        ),
    ),
);


var_dump (search_incomplete ('level', $array));
var_dump (search_incomplete ('root', $array));
var_dump (search_incomplete ('foo', $array));
