What role do arrays play in this scenario and how can they be utilized to solve the problem?

In this scenario, we need to store a list of items that a user has selected from a form. Arrays can be used to store these selected items efficiently and manage them easily. By using arrays, we can dynamically add or remove items from the list, iterate through the items for processing, and perform operations like filtering or sorting on the list.

// Initialize an empty array to store selected items
$selectedItems = [];

// Add selected items to the array
if(isset($_POST['item'])) {
    foreach($_POST['item'] as $item) {
        $selectedItems[] = $item;
    }
}

// Display the selected items
foreach($selectedItems as $item) {
    echo $item . "<br>";
}
