If you are doing something that needs to iterate a billion times, you shouldn't be using PHP. Things like calculating a fractal is just not what PHP was meant for. The vast majority of Web apps have absolutely no need to iterate that many times. You wouldn't try to show a user a billion database records on a single page, for example. Chances are pretty good that you are going to iterate less than 1000 times on a typical request and if you do end up having to iterate more for some reason, you would probably cache the result somewhere so you don't have to do it on a subsequent request. -Rasmus
