Thread

I am going to start a new complex web application with CodeIgniter and I have already done another project with CodeIgniter v1.7.1 while a go. I was wondering if it would be fine if I use the older version for my new project as well since I can do code reuse and have access to all the tutorials and documents for that version that makes developing the project much easier for me. Considering v2.0.3 is new and there are not many documents and tutorials available for it yet.

I appreciate any feedback and suggestions.

They are “almost” identical, so you better use the latest version.
The differences between the two are mostly changes in the system files, although there are some new stuff related to the application but they are few.

Tutorials, videos and documentation are almost the same for 2.x as for 1.7.

Thanks a lot for your prompt response. In what areas should I look for changes except the system files?
Also where can I find any document or tutorial specific to the latest version?

1.7.x tutorials are usually valid as long as you know what is different between the two versions.
You can read this blog entry by Phil Sturgeon: http://philsturgeon.co.uk/blog/2010/05/upgrading-to-codeigniter-2.0
And then I suggest you check the upgrade instructions in the userguide and see what is different.

Should take you about 5-15 minutes to get updated on the changes 😊

Thanks a lot. Very helpful info and all I needed to know for start:)
