It doesn't act weird. There is no block scope in PHP, so at the end of the first loop $i is a reference to the last element of $ii and in the second loop you are now assigning values to that reference which means you are overwriting the 3rd element of $ii each time through the loop. That of course means that once you get to the 3rd element of $ii it is no longer 3 and you see the last value assigned to it, which was 2.
