Adding a line break in PHP feed output

Last Modified: 2016-02-27

I am trying to edit a feed that is created for my blog extension. I want to place a line break after each tag (there is another problem with the feed and bugs are hard to find when it is all on one line) but I cannot get it to work. I have tried /n but this just outputs /n.

It is not echo so I am not sure this is correct to use. Here is the code

            $output  = '<?xml version="1.0" encoding="UTF-8" ?>';
            $output .= '<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">';

Open in new window

I have tried

            $output  = '<?xml version="1.0" encoding="UTF-8" ?> /n';
            $output .= '<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom"> /n';

Open in new window

this just outputs

<?xml version="1.0" encoding="UTF-8" ?>/n<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom"> /n

I have also tried

            $output  = '<?xml version="1.0" encoding="UTF-8" ?>';
			$output  = "\n";
            $output .= '<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">';
			$output  = "\n";

Open in new window

This makes these lines disappear and replaced with a single line break.

Can someone please give me some advice?

Many Thanks
