Hi,

This short pull request fix the issue #395.

Methods signatures from the PHP documentation:

• ArrayAccess

interface ArrayAccess {
	/* Methods */
	public offsetExists(mixed $offset): bool
	public offsetGet(mixed $offset): mixed
	public offsetSet(mixed $offset, mixed $value): void
	public offsetUnset(mixed $offset): void
}

• Iterator

interface Iterator extends Traversable {
	/* Methods */
	public current(): mixed
	public key(): mixed
	public next(): void
	public rewind(): void
	public valid(): bool
}

Regards.
