PHP对关联数组的array_sum

Question

我有一个关联数组(动态-可能有更多数组但相同的键):

  Array
 (
    [food] => Array
      (
        [0] => 3
        [1] => 4
        [2] => 1
      )
     [liquor] => Array
       (
         [0] => 4
         [1] => 5
         [2] => 0
       )
     [beer] => Array
      (
        [0] => 5
        [1] => 6
        [2] => 0
      )
  )

我需要对每个数组使用array_sum，所以结果将是:

Array ( [food] => 8, [liquor] => 9, [beer] => 11 )

谢谢!
