A pretty standard case of someone not really understanding references in
PHP. There is no need for this function to return a reference. They
are likely doing it to try to avoid a copy, but no copy will be made in
the standard return by value case. Simply remove the & from the
function definition to get rid of this notice.

Are you sure you have the right code snippet here? That's not a return
line and I see no references there.
