数组顺序 - 数组

Question

我正在尝试按特定顺序对数组进行排序:

我的代码(当前数组):

Array
(
[25] => Array
    (
        [1st place] => 
    )

[15] => Array
    (
        [2nd place] => 
    )

[10] => Array
    (
        [3rd place] => 
    )

[5] => Array
    (
        [4th place] => 
        [5th place] => 
        [6th place] => 
        [7th place] => 
        [8th place] => 
        [9th place] => 
        [10th place] => 
    )

[1] => Array
    (
        [11th place] => 
        [12th place] => 
        [13th place] => 
        [14th place] => 
        [15th place] => 
        [16th place] => 
        [17th place] => 
        [18th place] => 
        [19th place] => 
        [20th place] => 
        [21st place] => 
        [22nd place] => 
        [23rd place] => 
        [24th place] => 
        [25th place] => 
    )

)

需要数组:

Array
(
[0] => Array
    (
        [1st place] => 25
    )

[1] => Array
    (
        [2nd place] => 15
    )

[5] => Array
    (
        [3rd place] => 10
    )

[3] => Array
    (
        [4th place] => 5
        [5th place] => 5
        [6th place] => 5
        [7th place] => 5
        [8th place] => 5
        [9th place] => 5
        [10th place] => 5
    )

[4] => Array
    (
        [11th place] => 1
        [12th place] => 1
        [13th place] => 1
        [14th place] => 1
        [15th place] => 1
        [16th place] => 1
        [17th place] => 1
        [18th place] => 1
        [19th place] => 1
        [20th place] => 1
        [21st place] => 1
        [22nd place] => 1
        [23rd place] => 1
        [24th place] => 1
        [25th place] => 1
    )

)

这个想法就像使用数组位置(？)作为键的值并按此顺序设置数组:

我正在尝试使用该代码(php)

foreach ($newOptions as $ord) {
            $place = $ord[$idx];
            $value = $ord[$idx][0];
            $newOrderarr[$idx][$value][$place] = $name2;
            $idx++;
        }

但是,并没有正常工作$ newoptions是我正在使用的数组...

没有人选择明显的排序方法？

uasort($data, function($a, $b) {
    reset($a);
    reset($b);
    $aVal = (int) key($a);
    $bVal = (int) key($b);

    if ($aVal < $bVal) {
        return -1;
    } elseif ($bVal < $aVal) {
        return 1;
    } else {
        return 0;
    }
});

请注意,这会重置子数组中的内部指针,但这不太可能是一个问题,无论如何它们可能都是副本.此外,如果你有一个空的子数组,它将无法工作.在那种情况下,我只是先调用array_filter它来删除空值.
