Simple question...
I have seen people tell me to use "\r\n" in various places and others tell me to use "\n" in the same place. I'm sure one is right and one is wrong. Example - when designing mail() headers:

You may choose to expand it when extracting later.
Note that a \r in places other than just before a \n may hold other significance and so you shouldWhen storing it is acceptable to only use \n .
