Replace:

if ($_SERVER['HTTP_REFERER'] != "") {

with:

if (isset($_SERVER['HTTP_REFERER']) && $_SERVER['HTTP_REFERER'] != "") {

In fact, do it like this:
if (isset($_SERVER['HTTP_REFERER']) && $_SERVER['HTTP_REFERER'] != "") {
        $ref=$_SERVER['HTTP_REFERER'];
} else {
        $ref=null;
}
 
if(eregi('sitename', $ref)) {
        echo 'good';
}else{
        echo 'bad';
}
