Say you have a function that builds a fairly large array and then
returns it. If you just return it as usual PHP will make a copy of
that array and therefore use twice the amount of memory than it needs to.
References also provide a way to return more than one variable from a
function, but I doubt many PHP developers come across the need to do
that.
How can that be done with references?
