It seems like you code against a concrete implementation and not the interface ArrayAccess as the method count() does only exist in the following implementations of said interface: ArrayIterator, ArrayObject, CachingIterator, Issue523, PHP_Token_Stream, Phar, PharData, RecursiveArrayIterator, RecursiveCachingIterator, SplDoublyLinkedList, SplFixedArray, SplObjectStorage, SplQueue, SplStack, itertools\Queue.

	public function next()
	{
		$this->index += 1;
	}

	public function key()
	{
		return $this->index;
	}

	public function current()
	{
		return $this->array[$this->index];
	}

	public function seek($position)
	{
		$this->index = $position;
	}
