Maybe you should structure it a little different.
You now have 5 articles per magazine all with a number as their title. Just for the demo. Hope it helps.
You can access all articles via the $articles array then by providing the magazine title as key.
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.
