The essential skills required to develop applications quickly using CodeIgniter.

Developing PHP web applications is faster if you use a framework. There are many available frameworks, but some require a lot of configuration to get started, and need a powerful server to run. CodeIgniter is a lightweight but powerful framework, that's easy to install, and works well on shared hosting. On this course, we'll start from scratch, starting with installing the framework, through developing a complete web application, to ultimately installing it on a live server.

I designed the course to be easily understood by PHP developers who have no previous experience of a framework, and who want to develop full, feature-rich applications quickly and easily.
