How to set up Apache?

Question

Apache HTTP Server

Hello. I am learning PHP. To do this, I created a training project in a separate folder, launched a PHP server in it, got the result I needed on localhost, it works. I installed Apache 24, installed PHP, put the project folder in htdocs, registered the path to index.php in httpd.conf DocumentRoot, restarted, I go to localhost - the start page loads, but the links do not work. If everything worked on the PHP server, then the problem is probably in the Apache settings. Tell me what can be done.
