我有以下数据结构,我想根据前后值对其进行排序.

array (size=5)
  0 => 
    array (size=3)
      'id' => int 14
      'parentId' => int 0
      'before' => int 15
  1 => 
    array (size=3)
      'id' => int 15
      'parentId' => int 0
      'after' => int 14
  2 => 
    array (size=3)
      'id' => int 9
      'parentId' => int 0
      'after' => int 15
  3 => 
    array (size=3)
      'id' => int 8
      'parentId' => int 0
      'after' => int 9
  4 => 
    array (size=3)
      'id' => int 1
      'parentId' => int 0
      'after' => int 14

有没有巧妙的方法用PHP做到这一点？
