how can i find the version of codeigniter an application was written in?
codeigniter
Solution
Inside the framework, it's defined in 'CI_VERSION'.
Path is system/core/CodeIgniter.php
define('CI_VERSION', '2.1.3');
Problem
I'm reviewing someone's code and I can see that they're using codeigniter. But I'm trying to figure out which version they've used. I've been rooting around in the directory structure to find some information but haven't been successful yet. Thanks.
