My_controller

[saboortanha]

Hello,
Can someone help me understand this in MY_Controller
$this->load->view($page, $data);
Like I understand that it loads view but not sure what type of data is stored in those to variables
$page
$data

Here is complete function code
public function render_template($page = null, $data = array())
{

	//$this->load->view('admin/include/header',$data);
	$this->load->view('templates/header');
	//$this->load->view('templates/header_menu',$data);
	//$this->load->view('templates/side_menubar',$data);
	$this->load->view($page, $data);
	//$this->load->view('templates/footer',$data);
}

Thank you,
