"My" Harry was taken away to the Knockturn Alley by Floo powder. Hagrid already rescued him from the alley and Harry could meet Weasleys safely. That's great.
By the way, when Harry met Weasleys, Ron's father repaired Harry's broken glasses. In the movie, Hermione did it by "(Oculus) Reparo" that was the same spell used when she had met Harry for the first time. I like that scene pretty well but it's disappointing in the book.
