[SOLVED]Going to install directory doesn't start the installer

[The guy]

Hello! I am trying to set up MyBB on Arch Linux. I have installed php, apache and mariadb. I copied the contents of Upload/ to /srv/http. When going to my main site (using my IP address "xxx.xxx.x.x", http://xxx.xxx.x.x), and navigating to installer/ I can't get anything but the list with the directory contents. Is this what should happen?

I am using Chromium.

Thanks for any help you can provide.

Edit: I just needed to set up a php client.
