What is the correct way to change the quantity of a specific item in a PHP array?

To change the quantity of a specific item in a PHP array, you can access the item by its key and update the quantity value accordingly. You can do this by directly assigning a new quantity value to the item in the array using its key.

$items = [
    'item1' => ['name' => 'Item 1', 'quantity' => 5],
    'item2' => ['name' => 'Item 2', 'quantity' => 3],
    'item3' => ['name' => 'Item 3', 'quantity' => 2]
];
