Only double quoted strings interpret the escape sequences \r
and \n
as ‘0x0D’ and ‘0x0A’ respectively, so you want:
"\r\n"
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).
