Learning with CI2 Tutorial, but using CI3?

Just a quick reply to timd.mackey and hicham,

There are quite a bit of changes between 2.x and 3. As you probably know, 3 hasn't officially been released yet, so there aren't many tutorials floating around for it yet. I'm sure once it's released that will change. It shouldn't be too much longer as they're into the Release Candidates now.

But the best place to find the differences is in the userguide to upgrade from 2.x to 3.

CI 2 and CI 3 not the same way to call class and functions ,can you explain to us if there are a lot of changes or a little ,i want know if someone can write code using CI 2  can write code using CI 3    

Your best bet is to read through the upgrade guide, I have a few websites that are currently written using CodeIgniter 2 which I have recently upgraded to version 2.2.1, as these are fairly large and involved sites, I will hold off upgrading them to 3xx until it is fully released, as the changes for these sites would take a while to do.

They have a CodeIgniter Tutorial, but it's for CodeIgniter 2, and I plan to use CodeIgniter 3. I'm wondering how much I'm going to have to re-learn if I learn based on CodeIgniter 2 and then move to CodeIgniter 3?

There is a tutorial using CodeIgniter 3xx in the userguide which you can work through that may help answer your questions, @timd.mackey I am sure video tutorials will follow nearer the final release date for CI 3xx
