Write some code that will add another row and another column to it, filled with random values:

[
	[11, 12, 13, 14],

Let the database store a table of the following type:

orders table
id	name	date	price	amount
1	prod1	2020-12-31	100	3

Using the data in this table, get an array containing the sum of orders by year and month:

[
	'2020' => [
		'01' => '...',
		'02' => '...',
	],
	'2021' => [
		'11' => '...',
		'12' => '...',
