";
    $output .= "";
    $output .= "";
    $output .= "" . $VARIABLE_NAME . "";
    $output .= "";
    $output .= "";
    if (is_array($data)){
        foreach ($data as $key => $value) {
            //$value = dumpr($key, $value);
            $output .= "";
            $output .= "$key";
            $output .= "$value";
            $output .= "";
        }
    } else {
        $output .= "";
        $output .= "$data";
        $output .= "";
    }
    $output .= "";
    $output .= "";
    return $output;
}
?>

Use like this:

echo dumpr(‘SESSION’,$_SESSION);
etc..
