PHP seems to break my RSS page, help?

Question

I have a xml declaration in top of my page like this

   echo "<?xml version="1.0" encoding="ISO-8859-1" ?><rss version="2.0">";

and ?> in the echo seems like php thinks it's a closing statement or something. Am I missing something or is there some other workaround this?

By the way the page is a view in my codeigniter project, if that does matter...

Answer 1

Just replace outer double quotes with single quotes?

echo '<?xml version="1.0" encoding="ISO-8859-1" ?><rss version="2.0">';

Answer 2

It's probably your duplicate use of double quotes within a string, as the other answers point out.

Maybe you are also forgetting the surrounding PHP openers.

The full first line should look like this:

<? echo '<?xml version="1.0" encoding="ISO-8859-1" ?><rss version="2.0">';?>

Answer 3

You should escape your quote characters:

echo "<?xml version=\"1.0\" encoding=\"ISO-8859-1\" ?><rss version=\"2.0\">";

Answer 4

Escape the " or do this instead:

echo '<?xml version="1.0" encoding="ISO-8859-1" ?><rss version="2.0">';

(replacing " with ')

Answer 5

syntax should be:

header("Content-Type: application/xml; charset=ISO-8859-1");
echo '<'.'?xml version="1.0" encoding="ISO-8859-1" ?'.'><rss version="2.0">';

Reasoning:

1. it's very important to set the headers, as some readers go crazy if you don't explicitly declare XML.
2. the <? and ?> parts of the decleration should be split into benign strings, for good measure.
