I am in the process of learning CI but one thing i'm just not sure what it's for
Code:
class Welcome extends CI_Controller {
function index() {
parent::__construct();
$data['something'] = "something";
$this->load->view('includes/header', $data);
}
}parent::__construct(); .. what it is this for, what is it actually doing?
I've removed it from my code and it still works fine. I've checked a few guides, most say it's needed but nothing more.

The Welcome class extends the CI_Controller class.
parent::__construct() calls the constructor of the parent class. What is does depends on the code in that constructor.

personally I use constructors to do things that will be needed before running any functions in the class. specifically I use it to load libraries, helpers and models that I know will be used in all or most of my functions. I also like to throw this
Code:
//$this->output->enable_profiler(TRUE);in the constructor. That way If I am having problems I just uncomment it and all the functions will show the profiler.
