如何根据php中的索引数组对2个维数组进行排序？

Question

Array
(
    [0] => Array
        (
            [0] => black
            [2] => brown
            [1] => red
        )

    [1] => Array
        (
            [2] => car
            [0] => bicycle
            [1] => motorcycle
        )
)

我如何得到数组，这样：

恢复：

Array
(
    [0] => Array
        (
            [0] => black
            [1] => red
            [2] => brown
        )

    [1] => Array
        (
            
            [0] => bicycle
            [1] => motorcycle
            [2] => car
        )
)

您可以尝试这样的尝试：

Answer 1

$arr=array(
    array(2=>'red',1=>'green',3=>'black'),
    array(1=>'pink',3=>'blue',2=>'yellow')
);
array_walk( $arr, function(&$v,$k){
    ksort($v);
});
echo '<pre>', print_r( $arr, true ), '</pre>';

输出：

Array
(
    [0] => Array
        (
            [1] => green
            [2] => red
            [3] => black
        )

    [1] => Array
        (
            [1] => pink
            [2] => yellow
            [3] => blue
        )

)

使用krsort（）函数按键根据键。
