Question

当我单击index.php上指向users.php页面的链接时，我得到的数据与index.php上的数据相同，并且应该有所不同。我到users.php的链接路线很好，我认为问题出在核心控制器（Core.php）中，我似乎找不到问题。控制器名称也是UserController，当我将users.php的名称更改为usercontroller.php并将href更改为usercontroller时，它也可以正常工作。这是我的代码：

代码结构：

Project
 |    
 +-- App
 |   |  
 |   +-- Controllers
 |       |
 |       +-- PageController.php
 |       +-- UserController.php  
 |   +-- Libraries
 |       |
 |       +-- Core.php
 |       +-- Controller.php
 |   +-- Views
 |       |
 |       +-- pages
 |           |
 |           +-- users.php
 |           +-- index.php

index.php：

<?php require '../App/Views/includes/header.php' ; ?>
<h1>Homepage!!!</h1>
<a href="users">Users</a>
<?php require '../App/Views/includes/footer.php' ; ?>

PageController.php

<?php
namespace App\Controllers;

use App\Libraries\Controller;

class PageController extends Controller
{
    public function index()
    {
       $this->view('pages/index');
    }
}

UserController.php：

<?php
namespace App\Controllers;

use App\Libraries\Controller;

class UserController extends Controller
{
    public function index()
    {
       $this->view('pages/users');
    }
}

Controller.php：

<?php
namespace App\Libraries;

class Controller
{
    public function model($model)
    {
       require_once '../App/Models/' . $model . '.php';
       return new $model();
    }

    public function view($view, $data = [])
    {
       if (file_exists('../App/Views/' . $view . '.php')) {
        require_once '../App/Views/' . $view . '.php';
       } else {
         die("View does not exist!!!");
       }
    }
 }

Core.php

<?php
namespace App\Libraries;

class Core
{
   protected $currentController = 'App\Controllers\PageController';
   protected $currentMethod = 'index';
   protected $params = [];

   public function __construct()
   {
       $url = $this->getUrl();
       if (file_exists('../App/Controllers/' . ucwords($url[0]). '.php')) {
        $this->currentController = ucwords($url[0]);
          if (isset($url[0])) {
            $this->currentController = '\App\Controllers\\' . ucwords($url[0]);
        }
          unset($url[0]);
        }
          $this->currentController = new $this->currentController;

       if (isset($url[1])) {
         if (method_exists($this->currentController, $url[1])) {
            $this->currentMethod = $url[1];
            unset($url[1]);
          }
        }
          $this->params = $url ? array_values($url) : [];
          call_user_func_array([$this->currentController, $this->currentMethod], $this->params);
   }

public function getUrl()
{
    if (isset($_GET['url'])) {
        $url = rtrim($_GET['url'], '/');
        $url = filter_var($url, FILTER_SANITIZE_URL);
        $url = explode('/', $url);
        return $url;
       }
    }
 }

这是因为现在您正在搜索名为Users的控制器。您应该将控制器名称和文件名从UserController更改为Users，或者可以将其添加到Core类中：

   public function __construct()
   {
       $url = $this->getUrl();
       if (file_exists('../App/Controllers/' . ucwords($url[0]). 'Controller.php')) {
        $this->currentController = ucwords($url[0]);
          if (isset($url[0])) {
            $this->currentController = '\App\Controllers\\' . ucwords($url[0]).'Controller';
        ...
    }

现在，如果您有例如/ users的网址，则应将控制器命名为UsersController

由于路由问题，无法链接到另一个页面吗？
