How to escape the delimiter from the column content when export csv?

Just use fputcsv it takes care of escaping and producing correct csv data.

The usual way is to wrap the piece of data with a pair of " and use "" to represent a double quote character in the data.

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.
