\ N in unix
\ R \ n for windows

PHP can be replaced with PHP_EOL to improve the source code portability.

For example:

[Php]
Echo PHP_EOL;
// Windows platforms are equivalent to echo "\ r \ n ";
// The unix/linux platform is equivalent to echo "\ n ";
// Mac platform is equivalent to echo "\ r ";

Echo PHP_EOL;
// Windows platforms are equivalent to echo "\ r \ n ";
// The unix/linux platform is equivalent to echo "\ n ";
// Mac platform is equivalent to echo "\ r ";

We can use the get_defined_constants () function to obtain all PHP constants.
