How to create a newline character?

In PHP I am trying to create a newline character: echo $clientid; echo ' '; echo $lastname; echo ' '; echo '\r\n'; Afterwards I open the created file in Notepad and it writes the newline literally: > 1 John Doe\r\n 1 John Doe\r\n 1 John Doe\r\n I have tried many variations of the `\r\n`, but none work. Why isn't the newline turning into a newline?
