php 将一维数组转换成二维数组
一维数组：Array([1969-12-31]=>10[1969-12-30]=>20[1969-12-29]=>5[1969-12-28]=>6[1969-12-27]...
一维数组：Array ( [1969-12-31] =>10 [1969-12-30] => 20 [1969-12-29] => 5
[1969-12-28] => 6 [1969-12-27] => 30 [1969-12-26] => 70 [1969-12-25]
=> 33）
转换成这样的二维数组：Array ( [0] => Array ( [day] => 1969-12-31 [sum] => 10 ) [1] => Array ( [day] => 1969-12-30 [sum] => 20 ) [2] => Array ( [day] => 1969-12-29 [sum] => 5 ) [3]... )
怎么转？
