But I think the original question was about a tree that took a long time to create, and application variables would be a plus in this situation.....
Again, if you're just talking about reading, how hard is it to just do this to save:
$save_data = '<?php $array = ' . var_export($array) . '; ?>';
Now save that to a RAM disk and include() it whenever you need it recreated. You can do the same thing with objects, too.
