As I understood, \n was strictly a line feed (ASCII character 10), not
an "OS agnostic" end-of-line terminator. It happens to be the line
terminator for *nix. Windows uses the combined carriage return and
line feed characters (ASCII characters 13 and 10) which are
represented by \r\n in PHP, while Mac used only the the carriage
return. There is a PHP constant PHP_EOL that I'm pretty sure is
supposed to represent the line terminator defined on the operating
system of the computer executing the script, but I don't think it is
truly "agnostic" either. At least, if you have a text file saved in
Windows and split it on a Linux machine based on PHP_EOL, I believe
all of your array values will have a carriage return character hanging
on the end of them. Am I mistaken?
