在Wordpress functions.php中替换PHP代码

I'm trying to add a last item to the wordpress primary menu. So here is my question:

I have a code in functions.php that works well:

function add_last_nav_item($items) {
  return $items .= '<li><a href="#" >Contact</a></li>';
}
add_filter('wp_nav_menu_items','add_last_nav_item');

I need to replace which is inside the <li> tags with this:

<li><?php if(function_exists(wp_forecast)) { wp_forecast( wp_forecast("A") ); } ?></li>

I tried but it doesn't work.

    Try this:

    function add_last_nav_item($items) {
        ob_start();
    
        echo '<li>';
    
        if (function_exists('wp_forecast')) { 
            wp_forecast( wp_forecast("A") );
        }
    
        echo '</li>';
    
        $end = ob_get_clean();
        $items = $items . $end;
        return $items;
    }
    add_filter('wp_nav_menu_items','add_last_nav_item');
