按数字优先级排序多维数组

Question

我的阵列是这样的：

Array
(
    [0] => Array
        (
            [name] => abc-def-12
            [qty] => 250
            [sub_qty] => 1385
            [Location] => NOP01
        )

    [1] => Array
        (
            [name] => abc-def-23
            [qty] => 1234
            [sub_qty] => 615, 
101, 
432, 
116
            [Location] => NOP10, 
NOP04, 
NOP08, 
NOP06
        )

    [2] => Array
        (
            [name] => abc-def-34
            [qty] => 379
            [sub_qty] => 62
            [Location] => NOP08
        )

    [3] => Array
        (
            [name] => abc-def-45
            [qty] => 425
            [sub_qty] => 372, 
89
            [Location] => NOP07, 
NOP05
        )

    [4] => Array
        (
            [name] => abc-def-56
            [qty] => 0
        )

    [5] => Array
        (
            [name] => abc-def3.FMF
            [qty] => 523
            [sub_qty] => 240, 
103, 
180
            [Location] => NOP06, 
NOP08, 
    NOP11
            )
)

我在abc-def3.FMF之前abc-def-12排序数组时遇到问题。这是在我使用：

对数组进行排序之后

function sortNames($a, $b){
  return strcmp ($a['name'], $b['name']);
}

阻止名称排列如下：abc-def-12, abc-def-23, abc-def3.FMF, abc-def-34, abc-def-45, abc-def-56

我如何实现目标，以便数组打印如下：

Array
(
       [0] => Array
        (
            [name] => abc-def3.FMF
            [qty] => 523
            [sub_qty] => 240, 
103, 
180
            [Location] => NOP06, 
NOP08, 
    NOP11
            )        
       [1] => Array
        (
            [name] => abc-def-12
            [qty] => 250
            [sub_qty] => 1385
            [Location] => NOP01
        )

    [2] => Array
        (
            [name] => abc-def-23
            [qty] => 1234
            [sub_qty] => 615, 
101, 
432, 
116
            [Location] => NOP10, 
NOP04, 
NOP08, 
NOP06
        )

    [3] => Array
        (
            [name] => abc-def-34
            [qty] => 379
            [sub_qty] => 62
            [Location] => NOP08
        )

    [4] => Array
        (
            [name] => abc-def-45
            [qty] => 425
            [sub_qty] => 372, 
89
            [Location] => NOP07, 
NOP05
        )

    [5] => Array
        (
            [name] => abc-def-56
            [qty] => 0
        )
