So, like, are you sure that ++ really happens after the array assignment is
done?...
I'm probably just a Luddite, but I don't trust ++ and assignment operations
*that* far.

This looks suspicous... I'm not quite sure what's going on here, but I'm
expecting you'd want to walk from node to node, or maybe skip any
duplicates, but why are you zipping through the entire array looking for the
node that you are on?...
There's got to be a better way to track this -- maybe just using an indexed
array for your nodes, and knowing that you are currently on $node_index or
something...
Is a "node" an array? I wouldn't be using == on two arrays... Maybe it's
fine, but again that Luddite factor works in, and I'd be testing the
elements individually...
