PHP: Tips of the Day
PHP - how to create a newline character?
Only double quoted strings interpret the escape sequences \r and \n as '0x0D' and '0x0A' respectively, so you want:
Single quoted strings, on the other hand, only know the escape sequences \\ and \'.
So unless you concatenate the single quoted string with a line break generated elsewhere (e. g., using double quoted string "\r\n" or using chr function chr(0x0D).chr(0x0A)), the only other way to have a line break within a single quoted string is to literally type it with your editor:
$s = 'some text before the line break some text after';
Make sure to check your editor for its line break settings if you require some specific character sequence (\r\n for example).
