These are done with RewriteRule, a simple Google search willgive you mroe details.

In short, the URL will be broken down sorta like this: (Line 1, URL part, Line 2, PHP relative.

http://splur.gy
http://splur.gy/index.php

r
$_GET['var_1']

QqVYf
$_GET['var_2']

r
$_GET['var_3']

$_GET['var_4']

The RewriteMod will take the URL as setup in the above format, and pass the varialbes to a script. It is another way of posting variables in the URL.

As you see above: stackoverflow.com/posts/15182831, does not actually have a file named posts/15182831, it is simple used as a variable, passed to a script which queries that database, and spits out results based on what the script says.
