You have spaces in between the string '$_511a' so explode function must have a space also. So the index of $name will also be changed because now we have the first element on 0 index.
After the first name in the list all the names are preceded by a space. Explode() counts that space, putting a blank string in the 0 index in the resulting array.
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.
