Downloading and installing CodeIgniter
First things first, you will need a copy of CodeIgniter to be getting on with. There are several choices: you can download a nightly build, an older version, or the current stable release. However, it's recommended that you go for the latest stable version.
How to do it...
You can get your hands on the latest stable version of CodeIgniter through the following link:
http://codeigniter.com/downloads/
CodeIgniter will be offered as a compressed archive file. Once CodeIgniter has been downloaded, copy the package to your web folder, and unpack it as you would normally unpack an archive on your system. Once you've done this, you'll need to set some configuration options, which we'll look at next.
