All the other suggestions I've seen on this are essentially correct -- before the foreach runs, something somewhere has set $obj to be a reference to the last element of the array. It really doesn't matter whether you can find the culprit for this or not -- the solution is simply to put an unset($obj) immediately before the foreach statement -- this will break the reference (without destroying anything but $obj!) and make the foreach behave exactly as you want.
