$this->load->vars($array)

[eluser]Pascal Kriete[/eluser]
The load->vars function is used to pass variables to views (not to mention it extracts them). What you want here is a class variable.

Code:

class Blog {

    var $pr;

    function Blog()
    {
        parent::Controller();
        $this->pr = array(1, 2);
    }

    function index()
    {
        print_r($this->pr);
    ]
}
