Answer 1

You can do it like this:

$items = array("Item 1", "Item 2", "Item 3", "Item 4");

$item = glueItems($items);

function glueItems($items) {
    if (count($items) == 1) {
        $item = implode(", ", $items);
    } elseif (count($items) > 1)  {
        $last_item = array_pop($items);
        $item = implode(", ", $items) . ' and ' . $last_item;
    } else {
        $item = '';
    }
    return $item;
}
echo $item;
