Once installed (simply unzip the rar package in the root of our site is enough) we are going to provide our new framework with a few necessary configurations. You have to locate the file application/config/config.php There we will give all the necessary configurations to work well with our site, such as the path of our site in the variable :

Once we have these two configuration files edited and accommodated to our workspace, we can see how Doctrine works with Codeigniter. The great thing about this is to work through the console and that it automatically generates all the necessary files to abstract perfectly the classes of the different objects that compose our data model. To do this, and since I am currently working under Windows, we open our CMD and we go to our Codeigniter project (you should already know how to do this, use the cd command to go to c:path of your project) and thus be able to run the Doctrine client via command line.

$this->ci works because with $this->ci = &get_instance() you are calling a reference to the main controller class … again. If you look in the startup file (IIRC. Or the codeigniter.php file) there is the get_instance() function, which does nothing more than return (by reference) the instance of the CI_Controller class.

So, basically, calling $this->ci->load and $this->load are exactly the same, only that the first one is unnecessary inside a Controller / Model / View because the system is already doing it in the main class (through the method load).

If you take a look at the libraries, for example, you will see that using $this->ci->method() is necessary, because you need to have available all the methods of the CI_Controller, which is a kind of “superclass” that handles the whole framework.

Damien Pirsy has explained the question well and I will tell my experience: I found that &get_instance() returns the current controller that is handling this request, it inherits from most of the base CI_Controller; while $this->ci specifically means the CI_Controller instance – liar.
