php关于数组到数组

Question

在php中，我有一个这样的数组：

[
    [0] =>
        [
            [0] => 255
            [1] => 216
            [2] => 255
        ]
    [1] =>
        [
            [0] => 25
            [1] => 54
            [2] => 25455
        ]
]

现在我想要这样的数组：

[
    [0] => 255
    [1] => 216
    [2] => 255
]
[
    [0] => 25
    [1] => 54
    [2] => 25455
]

有什么好主意吗？用PHP语言！

Answer 1

检查一下，

<?php
        $arr = [
    0 =>
        [
            0 => 255,
            1 => 216,
            2 => 255,
        ],
    1 =>
        [
            0 => 25,
            1 => 54,
            2 => 25455,
        ]
];

echo json_encode($arr);

<强>输出

[[255,216,255],[25,54,25455]]

这是工作demo，

json_encode - 返回值

的JSON表示
