多维数组按另一个数组值排序

Question

I'm trying to sort out the sequence of individual array. How to use my another array list?

There is a predefined array:

$sortOrder = array("Night","Breakfast","Lunch","Dinner","Lying");

And this is it my original array content:

Array
(
    [Normal] => Array
        (
        [Dinner] => Array
            (
                [avgtime] => 17,06
                [avg] => 5.24
            )

        [Breakfast] => Array
            (
                [avgtime] => 04,25
                [avg] => 4.96
            )

        [Lying] => Array
            (
                [avgtime] => 14,49
                [avg] => 4.7
            )

        [Lunch] => Array
            (
                [avgtime] => 09,53
                [avg] => 5.26
            )

        [Night] => Array
            (
                [avgtime] => 00,00
                [avg] => 4.4
            )

    )

[High] => Array
    (
        [Dinner] => Array
            (
                [avg] => 9
                [avgtime] => 17,35
            )

    )

[Low] => Array
    (
        [Night] => Array
            (
                [avg] => 3.5
                [avgtime] => 02,35
            )

        [Breakfast] => Array
            (
                [avg] => 3.8
                [avgtime] => 07,12
            )
    )
)

How can I order placed based on the list? Please help me, and thanks so much!

To achieve more efficient key searching let's use static arrays in the comparison function:

foreach ($arr as $key => $row) {
  uksort($arr[$key], function($a, $b) {
    static $sortOrder = ['Night', 'Breakfast', 'Lunch', 'Dinner', 'Lying'];

    static $order;
    if (!isset($order)) {
      $order = array_flip($sortOrder);
    }

    $value = 0;
    if (array_key_exists($a, $order) && array_key_exists($b, $order)) {
      $value = ($order[$a] > $order[$b] ? 1 : -1);
    }
    return $value;
  });
}
