我想在php中按键对数组进行排序.但我使用的字母不是普通的英文字母,而是自创字母.这可能吗？

我的字母是

$alphabet = "AjawbpfmnrhHxXsSqkgtTdD =";

数组是这样的:

       [1] => mA
       [2] => =k
       [3] => Sfj,t
       [4] => =k

       )
   [aA_2] => Array(
       [0] => DI.7,4 &dwA-nTr& @Hrw-smA-tA,wj@
       [1] => snD
       [2] => aA
       [3] => Sfj,t
       [4] => jt
       [5] => jt,w
       )
  [sqA_1] => Array(
       [0] => DI.6,18 &dwA-nTr& @nswt@
       [1] => ra
       [2] => sqA
       [3] => Sfj,t
       [4] => =s
       [5] => r …
