In what scenarios would it be beneficial to use PHP SPL Lists?

PHP SPL Lists can be beneficial in scenarios where you need to work with a collection of data that requires efficient insertion, deletion, and traversal operations. Using SPL Lists can provide better performance compared to traditional arrays, especially when dealing with large datasets or frequently changing data. 

// Creating a new SPL DoublyLinkedList
$list = new SplDoublyLinkedList();

// Adding elements to the list
$list->push('apple');
$list->push('banana');
$list->push('orange');

// Removing an element from the list
$list->shift();

// Iterating over the list
$list->rewind();
while ($list->valid()) {
    echo $list->current() . "\n";
    $list->next();
}
