For some reason my PHP function call <? r(); ?> returns a fatal error. Any help?

<?php
//$r is previously assigned
function r() {
    echo ( $r );
};
?>

<html>
    <head>
        <link type="text/css" rel="stylesheet" href="<? r(); ?>rs/css/master.css">
    </head>

    If you want to refer to a global object from inside an object, you need to explicitly declare it as global:

    function r() {
    global $r;
    echo ( $r );
}

    But in general, referring to global variables in this way is bad style. You should consider passing in prerequisites as function arguments:

    function r($r) {
     echo ( $r );
}

...

r($r);
