如何更改數組索引並使用值序列？

Question

我以下面提到的格式獲得了名爲「Result」的數組。但是我想要下面提到的名爲「Desire_result」的數組。請幫助我接下來做什麼，以便我可以實現它。

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 
     ) 

    [2] => Array 
     (
      [0] => 2017-03-01 
      [1] => 2017-04-01 
      [2] => 2017-04-15 
      [3] => 2017-04-25 
     ) 

    [3] => Array 
     (
      [0] => 2017-05-01 
      [1] => 2017-05-13 
      [2] => 2017-05-20 
      [3] => 2017-05-26 
     ) 

    [4] => Array 
     (
      [0] => 2017-06-01 
      [1] => 2017-06-25 
      [2] => 2017-07-15 
     ) 

) 
?> 

Desire_result：

<?php 
Array 
(

    [0] => 2017-01-01 
    [1] => 2017-01-15 
    [2] => 2017-01-20 
    [3] => 2017-01-30   
    [4] => 2017-02-01 
    [5] => 2017-02-12 
    [6] => 2017-02-17 
    [7] => 2017-02-25 
    [8] => 2017-03-01 
    [9] => 2017-04-01 
    [10] => 2017-04-15 
    [11] => 2017-04-25 
    [12] => 2017-05-01 
    [13] => 2017-05-13 
    [14] => 2017-05-20 
    [15] => 2017-05-26 
    [16] => 2017-06-01 
    [17] => 2017-06-25 
    [18] => 2017-07-15 
) 
?>
