In PHP 5, objects are handled in a reference-like manner by default. So removing the & probably won't change anything.
It's not deprecated to return a reference but to not reflect that in your functions oder methods signature. There has to be an & before the name as well as when assigning the returned value.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
