Hi there
I think that foreach in your first example just knowns that this
should be the last loop (as the array only contains 1 element at
start) and so stops there.
In your 2nd example however the first loop isn't the last, so the
array get's checked again, and now there's another element, so...
I think that's more or less normal behaviour.
Sincerely yours
Louis
