hello -
i have watched a number of tutorials about xampp, and have installed it and have used it to to begin to learn PHP. but one thing that makes me nervous is that, the videos say that using xampp can open port 80 to the outside world.
i un-plug my router when i want to work on PHP in xampp, and xampp works fine (i can see what my coding is doing using localhost), but i want to know if this is necessary.
