Array of Associative Arrays in PHP

Very often in PHP, arrays appear that contain a set of some entities, for example, a list of users or a list of products.

Here is an example of such an array:

<?php
	$users = [
		[
			'name'   => 'user1',
			'age'    => 31,
			'salary' => 1000,
		],
		[
			'name'   => 'user2',
			'age'    => 32,
			'salary' => 2000,
		],
		[
			'name'   => 'user3',
			'age'    => 33,
			'salary' => 3000,
		],
	];
?>

As you can see, here we are dealing with an array of associative arrays. Despite the fact that this array is two-dimensional, as a rule, one foreach loop is used to iterate through it, which iterates over the subarrays. And the parts of the subarrays themselves are simply retrieved by key and output in the required order and format.

Let's output a column of our employees in some format as an example:

<?php
	foreach ($users as $user) {
		echo $user['name'] . ': ' . $user['salary'] . '$, ' . $user['age'] . '<br>';
	}
?>

The following array is given:

<?php
	$products = [
		[
			'name'   => 'мясо',
			'price'  => 100,
			'amount' => 5,
		],
		[
			'name'   => 'овощи',
			'price'  => 200,
			'amount' => 6,
		],
		[
			'name'   => 'фрукты',
			'price'  => 300,
			'amount' => 7,
		],
	];
?>

Using this array, output a column of products in some format you come up with.
