If you need the last key of your collection use:
<?php
array_key_last($this->getArrayCopy())
?>
In an extending class it could look like:
<?php
class Collection extends ArrayObject
{
public function lastKey(): int
{
return array_key_last($this->getArrayCopy());
}
}
?>
If you want to use any type safe collection:
<?php
class BookCollection extends Collection
{
public function add(Book $book) : void
{
$this->offsetSet($book->id, $book);
}
// note the return type "Book"
public function get(int $bookId) : Book
{
$this->offsetGet($bookId);
}
}
?>
