按数字键对数组进行排序

Question

我想以数字方式对数组进行排序，即188,188-1,188-2,222,222-1,222，-2等。这就是数组当前的样子：

[188-1] => Array
    (
        [time] => 1
    )

[188-2] => Array
    (
        [time] => 2
    )

[188-3] => Array
    (
        [time] => 3
    )

[188] => Array
    (
        [notes] => frog stand notes
    )

[489] => Array
    (
        [notes] => notes
    )

[489-1] => Array
    (
        [weight] => 10
        [reps] => 30
    )

[489-2] => Array
    (
        [weight] => 20
        [reps] => 30
    )

[489-3] => Array
    (
        [weight] => 30
        [reps] => 30
    )

[492-1] => Array
    (
        [weight] => 500
        [distance] => 100000
    )

[492] => Array
    (
        [notes] => more notes
    )

我尝试了一个ksort，ksort($sorted, SORT_DESC);但是使用带连字符的密钥并不能很好地工作，除非我做错了什么？

您可以将uksort()与strnatcmp()一起用作比较功能：

uksort($array, 'strnatcmp');
