如何PHP相对路径？

I am trying to include my JS file, which includes all core Javascript files in a PHP file, but I cannot get the relative/root path to work, so I could use it across all the pages which are located in sub folders etc.

Here is the structure:

In Dashboard I have this:

In folder family I have a file called addJob.php where I am trying to include a file bottomscripts.php which is in Dashboard/PHP/views/JS_includes/.

I have to use these across all the pages so how can I set the path? I tried using this:

<?php
define('BASE_URL', 'http://localhost/Hoidja.ee/Dashboard/');

echo ('<script src='.BASE_URL.'assets/js/gsap/main-gsap.js"></script>');
echo ('<script src='.BASE_URL.'assets/js/resizeable.js"></script>');
echo ('<script src='.BASE_URL.'assets/js/neon-api.js"></script>');
echo ('<script src='.BASE_URL.'assets/js/neon-custom.js"></script>');

?>

But this gives me forbidden error. I also tried $_SERVER['DOCUMENT_ROOT'] but this gives me failed to load local resource.

<?php
$basePath = $_SERVER['DOCUMENT_ROOT'].'/Hoidja.ee/Dashboard/';

echo ('<script src='.$basePath.'assets/js/gsap/main-gsap.js"></script>');
echo ('<script src='.$basePath.'assets/js/resizeable.js"></script>');
echo ('<script src='.$basePath.'assets/js/neon-api.js"></script>');
echo ('<script src='.$basePath.'assets/js/neon-custom.js"></script>');

?>
