What is the solution to the problem associated with functions and arrays?

Question

PHP

Good afternoon, please help me solve the problem in php: It is
necessary to create a function with any name, with one parameter - an array of positions in the basket.
The function should calculate and return how many items are in the cart (there can be several items in one item of the cart - the quantity field).
An array of the following structure will be passed to the function:
$basket = [
[
'position' => 'php book',
'quantity' => 1,
],
[
'position' => 'Wireless mouse',
'quantity' => 12 ,
]
];

The number of items in the basket can be from 0 to 10
At the same time, it is forbidden to use other functions, anonymous functions, type conversion, classes, global variables to solve the problem.

Answer 1

<?php

function total($array = []): int {
    $total = 0;
    foreach ($array as &$value) {
        $total += $value['quantity'];
    }
    return $total;
}

echo total([
    [
    'position' => 'книга по php',
    'quantity' => 1,
    ],
    [
    'position' => 'Мышь беспроводная',
    'quantity' => 12,
    ]
]);

Answer 2

Use a loop foreach. With it, you don't need any of the above.
