返回PHP数组名称

导读：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]

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
)

我在一个数组中有这两个数组.顶部数组将两者保持在一起,然后在下面各自单独存在.当我显示各个阵列时,如何回显他们的名字？

所以第一个是kanye,然后列出内容等.

希望有道理.我知道这将是一个简单的代码,但它让我很难过.

您可以使用 foreach语句来获取数组的键值对：

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