<?php

The method getValue() does not exist on loophp\phptree\Node\NodeInterface. It seems like you code against a sub-type of loophp\phptree\Node\NodeInterface such as loophp\phptree\Node\ValueNodeInterface or loophp\phptree\Node\ValueNode or loophp\phptree\Node\ValueNode.

            $hash = hash('sha256', $node->getKey() . $data);

The method getKey() does not exist on loophp\phptree\Node\NodeInterface. It seems like you code against a sub-type of loophp\phptree\Node\NodeInterface such as loophp\phptree\Node\KeyValueNode or loophp\phptree\Node\KeyValueNodeInterface or loophp\phptree\Node\KeyValueNode or loophp\phptree\Node\KeyValueNode.
