二维数组转化

[x] => Array
    (
        [0] => 2015-08-26
        [1] => 2015-08-27
        [2] => 2015-08-28
        [3] => 2015-08-29
        [4] => 2015-08-30
        [5] => 2015-08-31
        [6] => 2015-09-01
        [7] => 2015-09-02
    )

[data] => Array
    (
        [0] => 0
        [1] => 3
        [2] => 1
        [3] => 0
        [4] => 0
        [5] => 0
        [6] => 3
        [7] => 0
    )

将数组[x]和[data]变化成一个新的二维数组

[0] => Array
    (
        [0] => 2015-08-26
        [1] => 0
    )
[1] => Array
    (
        [0] => 2015-08-27
        [1] => 3
    )
[2] => Array
    (
        [0] => 2015-08-28
        [1] => 1
    )
依此类推，把全部的数据转化成下面数组格式
