php关于数组到数组

Question

In php ,I have a array like this:

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

And now I want array like that:

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

any good ideas? in php language!

Answer 1

Check this,

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

echo json_encode($arr);

Output

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

Here is working demo,
