模型视图控制器 - 自定义路由器的 CSS 问题 - PHP

我正在为我的 Web 应用程序创建自定义路由器。我使用 MVC。

例如，当我键入fab.app/portfolio一切都很好。但是当我输入fab.app/portfolio/时，css，图像和js没有显示。

这是因为路径会改变。在第一种情况下，它正在寻找图像的路径是fab.app/images/(the_image)但在第二种情况下它是 fab.app/portfolio/images/(the_image) .

此外，在索引中.php我必须为最后带有和不带斜杠的 url 提供一个条目。我不喜欢。我宁愿写它没有斜杠，它也应该与斜杠一起使用。

您可以在下面找到路由器和索引.php

索引.php

<?php
require_once __DIR__ . '/../vendor/autoload.php';
require_once __DIR__ . '/../app/setup.php';
use Fab'Controllers;
use Fab'Router;
$router = new Router'Router();
$router->get('/', 'MainController', 'index');
$router->get('/portfolio', 'ItemsController', 'showAllItems');
$router->get('/portfolio/', 'ItemsController', 'showAllItems');
$router->get('/portfolio/['w'd]+', 'ItemsController', 'single_item');
$router->get('/about', 'MainController', 'about');
$router->get('/contact', 'MainController', 'contact');
$router->get('/admin/dashboard', 'AdminController', 'index');
$router->get('/admin/dashboard/addItem', 'AdminController', 'addItem');
$router->get('/admin/dashboard/deleteItem', 'AdminController', 'deleteItem');
$router->get('/admin/dashboard/editItem', 'AdminController', 'editItem');
$router->get('/admin/dashboard/contactSupport', 'AdminController', 'contactSupport');
$router->post('/admin/addItem', 'AdminController', 'postAddItem');
$router->post('/admin/deleteItem', 'AdminController', 'postDeleteItem');
$router->post('/admin/editItem', 'AdminController', 'postEditItem');
//$router->get('/test', 'ItemsController', 'showAllItems');
////See inside $router
//echo "<pre>";
//print_r($router);
$router->submit();

在 html 中调用 css（以及图像和 js）的示例

<link href="/css/my-admin-custom.css" rel="stylesheet">

-------------------------------------------------------------------

为了清楚起见，以下是我解决问题的方式（根据@Max13的回答）。这将进入路由器.php：

        /**
         * If last char in URL is '/' redirect without it 
         * and also check if url is root '/' because this would result 
         * in infinite loop
         */
        if ( ($path[strlen($path)-1] === '/') && !($path === '/') ) { //
            $newPath = substr($path, 0, -1);
            header("Location: $newPath", true, 302);
            exit;
        }
