You still need to pass the value by reference to assign_children(),
so:
$new = &$leaf[$pid];
assign_children($pid,$list,&$new);
One last thing I fixed was that PHP was complaining that run-time pass
by reference was deprecated. I changed assign_children to be
function assign_children($id,$list,&$leaf)
Which solved that also!
Ah, pointers, how we love them. The bane of every CS undergrad.
