Well you haven't defined anything global in your code, unless you did
inapplyForumChildrenTree(), in which case it needs to be global
everywhere that you want to use it as global.
Easiest way would just be to use it like this everywhere:
$GLOBALS['treeResult'] = array(
'topics' => array(),
'posts' => array(),
'forums' => array(),
);
