Get path in php without index.php?

Question

PHP

I prescribe the meta in the pages that are generated in different folders (the names of the folders are also different and not known).

$url = ((!empty($_SERVER['HTTPS'])) ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

this displays the address of the current page with index.php
= https://site.ru/link/folder1/index.php

now the problem is how to display a link to an image that is in the same folder that is generated by the user

itself, this is not suitable because of the index .php at the end

?
how to remove from $url = ((!empty($_SERVER['HTTPS'])) ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; index.php
or we can output it in some other way
