PHP – how to create a newline character?

Posted By: Anonymous

In PHP I am trying to create a newline character:

echo $clientid;
echo ' ';
echo $lastname;
echo ' ';
echo 'rn';

Afterwards I open the created file in Notepad and it writes the newline literally:

1 John Doern 1 John Doern 1 John Doern

I have tried many variations of the rn, but none work. Why isn’t the newline turning into a newline?

Solution

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

"rn"

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 "rn" 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 (rn for example).
