Please make your answer complete by including relevant, formatted code inline(don't just link to ideone.com):
I could not put the link into the post because I would not be able to save it then. As I did not just link to ideone but also inserted the code the message seems misplaced to me.
Why is it there?
Although I cannot be sure it seems I was not the only one with this problem. The author of this answer to the same question seems to have used the same workaround as I did: Post the link as a comment.
