从最低到最高的吸收阵列

Question

我有这个数组，需要重新排序“第四层厚度”最低到最高。不知道我怎么能做到这一点。

有什么想法吗？

[thickness] => Array
    (
        [0] => Array
            (
                [TH Thickness ID] => 23
                [TH Thickness] => 100
            )

        [1] => Array
            (
                [TH Thickness ID] => 24
                [TH Thickness] => 120
            )

        [2] => Array
            (
                [TH Thickness ID] => 33
                [TH Thickness] => 150
            )

        [3] => Array
            (
                [TH Thickness ID] => 25
                [TH Thickness] => 50
            )

        [4] => Array
            (
                [TH Thickness ID] => 21
                [TH Thickness] => 60
            )

        [5] => Array
            (
                [TH Thickness ID] => 26
                [TH Thickness] => 70
            )

        [6] => Array
            (
                [TH Thickness ID] => 22
                [TH Thickness] => 80
            )

    )

PHP >= 5.5.0

array_multisort(array_column($array['thickness'], 'TH Thickness'), SORT_ASC, $array['thickness']);

PHP < 5.5.0 -您可以查看您的问题可能重复的内容，或者：

foreach($array['thickness'] as $k => $v) {
   $sort[$k] = $v['TH Thickness'];
}
array_multisort($sort, SORT_ASC, $array['thickness']);
