PHP routing and stylesheets

I'm trying to learn something about MVC, but I have problems including stylesheets correctly.

In my index.php I do require_once('views/layout.php');. Now I want to include my main.css which is placed at css/main.css, but I can't figure out how I could do that correctly, since the urls look like this: example.com/controller/action and the browser tries to load my stylesheets from example.com/controller/css/main.css

Now I could include the stylesheets like this: <link href="../css/main.css" rel="stylesheet">, but I don't think that this would be a good solution, since that wouldn't work with urls like example.com/controller/action/1.

I'd like to know if there's a good way to solve this problem. Thanks in advance!

Solution

  • I'd have a global variable name:

    $rootUrl = 'https://yourdomain.com';

    So wherever I need include style/script file, I use absolute path: 

    <script src="<?php echo $rootUrl . '/css/main.css' ?>" /><script>
