What does making a function a reference do?

[Deltran]

I've been having a hard time trying to find an answer to this:

What is the difference between [b]function myFunc()[/b]  and [b]function &myFunc() [/b]???

I've never seen that on functions. I know you can pass a variable by reference. Normally variables are passed by value, meaning a copy is made, whereas reference points to the actual variable.

Edit:

"Returning by-reference is useful when you want to use a function to find which variable a reference should be bound to."
