Inserting Multidimensional Array Elements in a Loop in PHP

Let's see how insertions are performed when iterating through multidimensional arrays. Suppose, for example, we have the following array:

<?php
	$users = [
		[
			'name' => 'user1',
			'age'  => 30,
		],
		[
			'name' => 'user2',
			'age'  => 31,
		],
		[
			'name' => 'user3',
			'age'  => 32,
		],
	];
?>

Let's iterate through it with a loop and form strings from its elements:

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

Let's simplify our code by using variable interpolation:

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

Let's simplify even more by removing quotes from the keys:

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

Given the following array:

<?php
	$products = [
		[
			'name'   => 'product1',
			'price'  => 100,
			'amount' => 5,
		],
		[
			'name'   => 'product2',
			'price'  => 200,
			'amount' => 6,
		],
		[
			'name'   => 'product3',
			'price'  => 300,
			'amount' => 7,
		],
	];
?>

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