php：按键排列多维数组？

Question

我需要一些嵌套数组按其键值按字母顺序排序...

是否有一个本地的PHP函数来排序如下这样的嵌套数组是为了像

[G] - >阵.. 。

[I] - >阵列...

[P] - >阵列...

[S] - >阵列...

[T] - >阵列...

这里是一个例子排序的数组：

[S] => Array 
    (
     [26] => Array 
      (
       [name] => St Georges Hall 
       [tel] => sdfa 
      ) 

     [27] => Array 
      (
       [name] => St Werburghs Community Centre 
       [tel] => sadf 
      ) 
    ) 

[G] => Array 
    (
     [40] => Array 
      (
       [name] => The Golden Guinea 
       [tel] => 
      ) 

     [41] => Array 
      (
       [name] => The Golden Lion 
       [tel] => One of Bristol's key live music pubs 
      ) 

    ) 

[I] => Array 
    (
     [45] => Array 
      (
       [name] => The Island 
       [tel] => asdfgf 
      ) 

    ) 

[P] => Array 
    (
     [50] => Array 
      (
       [name] => The Prom 
       [tel] => Reliable gig venue and blues hotspot on Gloucester road 
      ) 

    ) 

[T] => Array 
    (
     [51] => Array 
      (
       [name] => The Thunderbolt 
       [tel] => Small gig venue in Totterdown 
      ) 

     [52] => Array 
      (
       [name] => Tobacco Factory 
       [tel] => A modern cafe-bar with regular live music. 
      ) 

    )
