There is a test in the original PR, no need for 6004.

The test in 6002 did not fail for me without your patch.

@vicb can you explain what it fixes? As I said, your test does not cover something that would fail without the patch. So I don't see the bug.

@Tobion php.net states: The `current()` function simply returns the value of the array element that's currently being pointed to by the internal pointer and `reset()` returns the value of the first array element.

I have no clue what the "element that's currently being pointed to by the internal pointer" in this method so `reset()` is probably what you want.

Validated ?

I agree `reset()` is more explicit here. But `current()` should work just as well in this case because the array pointer can only be at the first item when calling the method. Anyway, this is good to merge. I just hoped there was a unit test that ensures this on my machine. This is why I added the test in my patch. Maybe Fabien can just merge the second commit on #6004

As explained in #6004, there is already a test from my first PR that made Travis go red.
