Array of PHP functions, shuffle and pop -
Tell us the which function we'll learn this stop...


Ok, I'm gonna be honest - in ten years of working with PHP, eight of which have been professionally, I've never called this function or any of its siblings. I started to do some research on this last week, but I got caught up on work. I know what streams are in principle - basically they are ways of linking up Unix programs to one another. But beyond that, I'm not sure.

So, who wants to step up to the plate and go over this one?
