I have array like this :
Array (
[2018-03-12] => Array (
[United States] => 4
[Australia] => 15
[United Kingdom] => 0
[New Zealand] => 0
)
[2018-03-13] => Array (
[United States] => 0
[Australia] => 8
[United Kingdom] => 2
[New Zealand] => 0
)
)
I want to make an array like this:
[
["2018-03-12", 4, 15, 0, 0],
["2018-03-13", 0, 8, 0, 2]
]
How can this be done?
