PHP：排序多维数组[关闭]

I have multi-dimension array like:

Array
(
    [name] => Array
        (
            [0] => South Africa
            [1] => Australia
            [2] => Egypt
        )

    [img] => Array
        (
            [0] => sa-flag.jpg
            [2] => au-flag.jpg
            [1] => eg-flag.jpg
        )
)

and I want to sort it alphabetically such that its output will exactly like:

Array
(
    [name] => Array
        (
            [0] => Australia
            [1] => Egypt
            [2] => South Africa
        )

    [img] => Array
        (
            [0] => au-flag.jpg
            [2] => eg-flag.jpg
            [1] => sa-flag.jpg
        )
)

I could not be able to use sort on both keys to synchronize the country name with country flag.

Please find below solution

$kd = array(
'name' => array(
        '0' => 'South Africa',
        '1' => 'Australia',
        '2' => 'Egypt',
    ),

'img' => array
    (
        '0' => 'sa-flag.jpg',
        '2' => 'au-flag.jpg',
        '1' => 'eg-flag.jpg',
    ),
);
array_multisort($kd['name'], SORT_ASC, SORT_STRING,$kd['img'], SORT_ASC, SORT_STRING);
echo '<pre>';
print_r($kd);

Find below core concept

Try this

$arr = array_multisort($array);
