php - 返回 PHP 数组名

Question

Array ( [kanye] => Array ( [0] => Kanya [1] => Janaye [2] => Kayne [3] => Kane [4] => Kaye ) [wst] => Array ( [0] => ST [1] => St [2] => st [3] => EST [4] => West ) )

Array
(
    [0] => Kanya
    [1] => Janaye
    [2] => Kayne
    [3] => Kane
    [4] => Kaye
)
Array
(
    [0] => ST
    [1] => St
    [2] => st
    [3] => EST
    [4] => West
)

我将这两个数组放在一个数组中。顶部阵列包含它们两个，然后下面是每个单独的阵列。当我显示单个数组时，如何呼应它们的名称？

所以第一个是kanye，然后列出内容等。

希望这是有道理的。我知道这将是一段简单的代码，但它难倒了我。

您可以使用 foreach获取数组键值对的语句:

$outer_arr = array('kanye' => array('Kanya', 'Janaye', 'Kayne', 'Kane'));
foreach($outer_arr as $key => $val) {
    print($key); // "kanye"
    print_r($val); // Array ( [0] => Kanya [1] => Janaye [2] => Kayne [3] => Kane )
}
