There's no need for it to be a flame war. The mysql extension is officially not recommended for writing new code, so anyone using it should be informed of this fact. I think it should consist of more than "don't use that," but at the very least that should cause the questioner to want to know why. http://php.net/intro.mysql This issue is problematic for exactly the reason Norah demonstrates above: "it's working." Great that in this case it hasn't been left at that, but most will see it work and think they've "got it right." I believe the community has a responsibility to give good advice and recommend best practices as well as directly addressing people's problems, so it's right that things like this get repeatedly pointed out where appropriate. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/
