<?php namespace Mbh\Tree\Visitor;
    public function visit(NodeInterface $node)
    {
        $nodes = [];
        foreach ($node->getChildren() as $child) {
            $nodes = array_merge(
                $nodes,
                $child->accept($this)

$child->accept($this) of type void is incompatible with the type null|array expected by parameter $array2 of array_merge().

Are you sure the usage of $child->accept($this) targeting Mbh\Tree\Interfaces\Node::accept() seems to always return null.

            );
        }

        $nodes[] = $node;

        return $nodes;
    }
