当我将 require_once() 与 ampps 一起使用时，出现 Permission denied 错误

Question

I am using require_once to call a function into index.php from Category.class.php but i am getting this error:

Warning: require_once(C:\Program Files\Ampps\www\admin-panel): failed to open stream: Permission denied in C:\Program Files\Ampps\www\admin-panel\admin-dashboard\Category.class.php on line 22

Fatal error: require_once(): Failed opening required '' (include_path='.;C:\php\pear') in C:\Program Files\Ampps\www\admin-panel\admin-dashboard\Category.class.php on line 22

This is the function i am trying to call:

public function index()
    {
        $db = new DataBase();
         $categories = $db->select("SELECT * FROM `categories` ORDER BY `id` DESC;");

        require_once(realpath(dirname(__FILE__) . "../template/admin/category/index.php"));
    }

And this is the .htaccess file:

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.+)$ admin-panel/index.php [QSA,L]

How can i solve this?

Answer 1

I found the solution, The problem was the syntax error:

I wrote require_once like this which is incorrect:

require_once(realpath(dirname(__FILE__) . "../template/admin/category/index.php"));

When i change it to following code problem was solved:

require_once(realpath(dirname(__FILE__) . "/../template/admin/categories/index.php"));
