  I'm using the jQuery Fancybox plugin to display some content on a website. Unfortunately, when a link is clicked, the lightbox that is loaded starts at the same scroll position as the previous one. I tried using self.scrollTo(0,0) $.scrollTo(0) $('#top').scrollTo(); and a few others methods to push it back to the top, but none have seemed to work. Any help on this?

  - by Adam

• Is SPLFileObject atomic?

  - by Jakub Lédl

  I'm wondering whether methods of PHPs SPLFileObject are atomic (e.g. thread-safe) or not? If they aren't, I'll implement my own class, which will use flock(), but is this enough? Is the flock function really thread-safe? What if the collision occurs after I fopen() the file, but before I flock() it?
