Because in PHP5, Object model is different from PHP4. This seems to be the
correct behavior, because the item you are adding to the array is an object,
which you keep referencing in every iteration of the loop, this would modify
prior assigned values as you advance in the loop. I find instantiating a
"User" object as the first line after fetching a good fix.
