Could anyone explain to me how to set up a testing server for my computer?
I’m going to assume you want to run PHP. If you’re running Windows, have a look at WAMP. It’s a bundle and installer for Apache, MySQL and PHP. On a Mac, the equivalent would be [URL=“http://www.mamp.info/”]MAMP.
If you want .NET, Ruby or something else, it’s a bit different but there’s lots of help available if you search for it on Google.
xampp (http://www.apachefriends.org/en/xampp.html) may be worth a look as well.
