仅对组合了数字、number_letters、letters_numbers和字母的数组进行排序

Question

我正在尝试排序和数组，但是无法按预期获得数组。

我有一个像这样的数组：

Array
(
    [0] => 5
    [1] => 7
    [2] => 8
    [3] => 9
    [4] => 10
    [5] => 11
    [6] => 12
    [7] => 13
    [8] => 14
    [9] => 15
    [10] => 16
    [11] => 17
    [12] => 18
    [13] => 19
    [14] => 20
    [15] => 21
    [16] => 23
    [17] => 24
    [18] => 26
    [19] => 28
    [20] => 29
    [21] => 30
    [22] => 31
    [23] => 32
    [24] => 33
    [25] => 34
    [26] => 35
    [27] => 36
    [28] => 37
    [29] => 38
    [30] => 39
    [31] => 40
    [32] => 41
    [33] => 42
    [34] => 44
    [35] => 46
    [36] => 48
    [37] => 50
    [38] => 52
    [39] => 54
    [40] => A
    [41] => B
    [42] => 3
    [43] => 4
    [44] => 6
    [45] => A1
    [46] => B1
    [47] => 1A
    [48] => 22
    [49] => 25
    [50] => 27
    [51] => 1B
)

当我运行asort($arr)时，它返回：

Array
(
    [47] => 1A
    [51] => 1B
    [42] => 3
    [43] => 4
    [0] => 5
    [44] => 6
    [1] => 7
    [2] => 8
    [3] => 9
    [4] => 10
    [5] => 11
    [6] => 12
    [7] => 13
    [8] => 14
    [9] => 15
    [10] => 16
    [11] => 17
    [12] => 18
    [13] => 19
    [14] => 20
    [15] => 21
    [48] => 22
    [16] => 23
    [17] => 24
    [49] => 25
    [18] => 26
    [50] => 27
    [19] => 28
    [20] => 29
    [21] => 30
    [22] => 31
    [23] => 32
    [24] => 33
    [25] => 34
    [26] => 35
    [27] => 36
    [28] => 37
    [29] => 38
    [30] => 39
    [31] => 40
    [32] => 41
    [33] => 42
    [34] => 44
    [35] => 46
    [36] => 48
    [37] => 50
    [38] => 52
    [39] => 54
    [40] => A
    [45] => A1
    [41] => B
    [46] => B1
)

它是正常排序，但是，我愿意有它排序的组合，如数字，NumbersLetters，LettersNumbers，字母。

例如，此数组应如下所示：

Array
(
    [42] => 3
    [43] => 4
    [0] => 5
    [44] => 6
    [1] => 7
    [2] => 8
    [3] => 9
    [4] => 10
    [5] => 11
    [6] => 12
    [7] => 13
    [8] => 14
    [9] => 15
    [10] => 16
    [11] => 17
    [12] => 18
    [13] => 19
    [14] => 20
    [15] => 21
    [48] => 22
    [16] => 23
    [17] => 24
    [49] => 25
    [18] => 26
    [50] => 27
    [19] => 28
    [20] => 29
    [21] => 30
    [22] => 31
    [23] => 32
    [24] => 33
    [25] => 34
    [26] => 35
    [27] => 36
    [28] => 37
    [29] => 38
    [30] => 39
    [31] => 40
    [32] => 41
    [33] => 42
    [34] => 44
    [35] => 46
    [36] => 48
    [37] => 50
    [38] => 52
    [39] => 54
    [47] => 1A
    [51] => 1B
    [45] => A1
    [46] => B1
    [40] => A
    [41] => B
)

您可以在uasort中使用用户定义的排序，请检查Demo

uasort($array,function($a,$b){
    if(is_numeric($a) && is_numeric($b)){
        return $a - $b;
    }elseif(is_numeric($a)){
        return -1;
    }elseif(is_numeric($b)){
        return 1;
    }else{
        $length = max(strlen($a),strlen($b));
        return strcmp(str_pad($a,$length,"z",STR_PAD_LEFT),str_pad($b,$length,"z",STR_PAD_LEFT));
    }
});
