Profile url unable to get result - php

Question

So I am wanting to allow my members to view a profile via a url such as: mywebsite.com/account/Username
however, at the moment my members can view via the url: mywebsite.com/account?username=username.
This doesn't look profesional and I've tried nearly everything to get it to the url I'm looking to get.
(Please be aware; I'm very new to this website and cannot use it properly, If I have done anything wrong, please notify me and I will justify it.)
The code:
//get config
$config = $base->loadConfig();

Your best bet is to use:
.htaccess route with mod_rewrite
Try Adding a file called .htaccess in your root folder, and add something like this:
RewriteEngine on
RewriteRule ^/?Some-text-goes-here/([0-9]+)$ /account.php?username=$username
This will tell Apache to enable mod_rewrite for this folder, and if it gets asked a URL matching the regular expression it rewrites it internally to what you want:
