Attach a branch to a node about tree

@Ziggizag

Apologies for the delay! Can you clarify, please?

Can you please enhance your brilliant code implementing (pseudocode) as follows:

1. $branch = $node->getBranch($childNode)

This should return an array defining $childNode (what is a child node of $node) with all its children.

I'm unsure what you mean by that, can you elaborate?

1. What node does $node refer to?
2. What node does $childNode refer to? Should it be a direct child of $node?
3. What should the structure of $branch look like? A list of nodes? Which nodes?

Hi,

The node is:

$node = new Node('foo');

$childNode is a direct child of a $node.

A $branch should be a structure keeping all information about a $childNode and all its children with their children and their children, etc. So, formally a $branch is a sub-tree.

The idea is to easily manipulate tree structure, like moving the entire branches (sub-trees) between nodes rather than re-creating them recursively.
