Bug description: "Returning References" could do with more info
Description:
------------
The Returning References manual page contains the following comment:
"Note: Unlike parameter passing, here you have to use & in both places -
to indicate that you return by-reference, not a copy as usual, and to
indicate that reference binding, rather than usual assignment, should be
done for $foo."
It refers to pass-by-reference, where you have to use the ampersand in
both the function *and* in the assignment of the function value to a
variable.
It is not clear what would happen if you didn't put the ampersand in both
places, and it would be nice to have someone explain this.
I'm a fairly seasoned PHP developer, but references are complex, and
judging by the user comments in various places in the manual concerning
them I think it would be great to have a sentance or two clarify this.
I know it's only a minor request, but for developers seeking to fine-tune
their code, understanding references is clearly the way to go.
Thanks, Scott.
