Ah, I understand now. Maybe you could construct the variable call as a
string, then eval it. I'm assuming you aren't searching, so you don't
need to search all the leaves of the tree, just query a particular
leaf.
For example:
$tree = array(...); //Your tree array that you will be querying.
$string = 'k1:k2:k3:...:kn';
$tree_query = '$val = $tree[\'';
$tree_query .= str_replace(':', '\'][\'', $string).'\'];';
eval($tree_query);
Recursion is complicated, but this way is pretty unsafe. If users
input $string, you are open to them inserting something that can be
run in php.
Avast!
