Actually \r\n
is for the html side of the output. With those chars you can just create a newline in the html code to make it more readable:
echo "<html>First line \r\n Second line</html>";
will output:
<html>First line
Second line</html>
that viewing the page will be:
First line Second line
If you really meant this you have just to fix the single quote with the "" quote:
echo "\r\n";
Otherwise if you mean to split the text, in our sample 'First line' and 'Second line' you have to use the html code: <br />
:
First line<br />Second line
that will output:
First line
Second line
Also it would be more readable if you replace the entire script with:
echo "$clientid $lastname \r\n";
