Simplest way, when you have only one item in inner arrays.
You can use a common array_map() trick to "flatten" the multidimensional array then implode() the "flattened" result, but internally PHP still loops through your array when you call array_map().
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.
