How to get controller name in Codeigniter?

@denis 

In Codeigniter, you can get the name of the current controller using the $this->router->fetch_class() function. This function returns the class name of the current controller.

Here is an example of how you can use this function:

1
2
3
4
5
6
7
8
9

class MyController extends CI_Controller {

    public function index()
    {
        $controller_name = $this->router->fetch_class();
        echo "The current controller is: " . $controller_name;
    }

}

This will output the name of the current controller, which in this case is MyController.

You can also use the $this->router->fetch_method() function to get the name of the current method being executed in the controller.

For example:

1
2
3
4
5
6
7
8
9

class MyController extends CI_Controller {

    public function index()
    {
        $method_name = $this->router->fetch_method();
        echo "The current method is: " . $method_name;
    }

}

This will output the name of the current method, which in this case is index.

Note: These functions are available in Codeigniter 3 and above. In earlier versions of Codeigniter, you can use the $this->router->class and $this->router->method properties to get the same information.
