from PHP manual, it said:

Do not use return-by-reference to increase performance, the engine is
smart enough to optimize this on its own
------------------
Why?
The bottom line from my view in using reference in all my codes are :
1. memory allocation need time! why not use reference?
2. you waste memory for storing two copies of data
Return-by-reference should at least faster, more efficient, so I can't
find a reason not using it.
