e.g.
$_SERVER['SCRIPT_NAME'] = file name after the domain
$_SERVER['SCRIPT_FILENAME'] = complete filename
What are the other ones and what do they do?

These are variables whose values are automatically filled in before your script starts to execute. You can use them anywhere in your scripts. See the list at
[php.net...]
If you plan to write a lot of PHP code, you can download the documentation from here: [php.net...]
In Windows, I use the .chm Help file with user notes. In Linux, I use the "many HTML files" version. I find both very usable.

A FYI, $_SERVER is one of the PHP superglobals (not functions, $_SERVER is a global array available to any part of a program,) and in other languages are called environment variables. They are extracted, and changed based on, the server software environment.
You can see them any time with
<?php
phpinfo();
?>
