Apache-htaccess 500内部服务器错误

Question

I'm learning how to make PHP MVC applications, and the tutorial I followed involved creating two .htaccess files - one to prevent a user from navigating to the application folders and files; the other to rewrite how the URL is presented in order for me to parse and retrieve controllers, methods and parameters.

When deploying these files on my XAMPP server, they work correctly. However, when deploying these files on to my university server via FTP, the 500 Internal Server Error appears, and removing these files will allow me to see my application. But I need these files otherwise I can't call the appropriate controllers, models and views.

I have searched around for the answer, and many solutions say that there could be syntax errors, which I don't believe I have any as it works on the XAMPP instance just fine. The other answers were that the server itself may not be configured to allow me to upload such files or something similar.

I do not have access to the configuration of my university's server, which I know may hinder any solutions you could provide to me. So, if there are any PHP solutions to at least let me parse the URL the way I need to, I'll be happy to drop the .htaccess files.

The first .htaccess file, located within the app directory of the application:

Options -Indexes

The second .htaccess file; located within the public directory of my application:

Options -MultiViews
RewriteEngine On

RewriteBase /~21249593/Internet_Technologies/Element_2/public

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f

RewriteRule ^(.+)$ index.php?url=$1 [QSA,L]

The PHP class used to parse the URL to call the appropriate controller and its method, I have posted the full logic so you can understand how the parsing works:

class App {
    protected $controller = 'home';
    protected $method = 'index';
    protected $params = array();

    public function __construct() {
        $url = $this->parseUrl();

        if (file_exists('../app/controllers/' . $url[0] . '.php')) {
            $this->controller = $url[0];
            unset($url[0]);
        }

        require_once '../app/controllers/' . $this->controller . '.php';

        $this->controller = new $this->controller;

        if (isset($url[1])) {
            if (method_exists($this->controller, $url[1])) {
                $this->method = $url[1];
                unset($url[1]);
            }
        }

        $this->params = $url ? array_values($url) : array();

        call_user_func_array([$this->controller, $this->method], $this->params);
    }

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

I appreciate any help you can give me here

EDIT

I should've stated that XAMPP is using 2.4.9 Apache, the FTP is 2.2.3

Answer 1

It does seem mod_rewrite or .htaccess usage in general is forbidden for your account. You should ask your administration if that can be changed, if not, you cannot use mod_rewrite urls.

What you can anyway do is to use urls like http://yourdomain/index.php?url=something , those should work regardless. For anything "cleaner" you would need a server configuration change.

Answer 2

Well, if you can't rewrite the URL you have to change the links to your application to the format your application needs them.

So insteaf of linking to mydomain.com/controller/method/param1/param2... you need to link to mydomain.com/index.php?url=controller/method/param1/param2..

The links are not that pretty anymore, but they will work.

Answer 3

Try to change 'Encoding' of '.htaccess' file. It worked for me. I used ANSI.
