I’m trying to create a generic, re-usable function that shows the site name on the login screen. It works with just static text, but how do I pull in the site name dynamically? Here’s what I’ve tried:

function custom_login_message() {
    $message="<p class="natz-login">Log in to <?php echo get_option( "name' ); ?> </p><br />';
    return $message;
    }
    add_filter('login_message', 'custom_login_message');

This is obviously wrong, but what do is use instead of <?php echo get_option( 'name' ); ?> ?
