配列インデックスを変更して値シーケンスを使用する方法は？

Question

私は、名前 "Result"で以下のフォーマットで配列を取得しました。しかし、私は、名前 "Desire_result"で以下に述べる配列を必要とします。私がそれを達成できるように、次に何をすべきかを助けてください。

結果：

<?php 
Array 
(
    [0] => Array 
     (
      [0] => 2017-01-01 
      [1] => 2017-01-15 
      [2] => 2017-01-20 
      [3] => 2017-01-30 
     ) 

    [1] => Array 
     (
      [0] => 2017-02-01 
      [1] => 2017-02-12 
      [2] => 2017-02-17 
      [3] => 2017-02-25
