Login to facebook with php sdk doesn return valid $user?

You are not setting the acces_token to facebook object. When user is redirected to your page after authentication, you should set the user access_token in your $facebook object and then call $facebook->getUser().

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.
