Windows uses \r\n
Linux uses \n
Mac uses \r

Depending on what tools you use to read/write/create the files, and
where the data comes from, it's possible that you have any of those
formats.

This is especially true of FORM data from a TEXTAREA.

I frequently do this:

$text = $_POST['text'];
$text = str_replace("\r\n", "\n", $text);
$text = str_replace("\r", "\n", $text);
//Now I *know* it's in Linux newline format.
