PS:when i want to display a list o programs that belong to a category & when i want to display the list of programs of channel that belong to a category ,the segment change so i wont use the segment i wanna get the id dynamically ..

Don't know if this is what you are after, but you can send parameters in a standard codeigniter install with URI and catch them in the method params.

class Welcome extends MY_Controller {

    public function index($a = NULL, $b = NULL, $c= NULL)
    {
        echo 'Testing params: <br> 
            Param1: ' . $a . '<br>Param2: ' . $b . '<br>Param3: ' . $c;
    }
}

Calling http://example.com/index.php/welcome/index/test1/test2/test3 will render

Testing params: 
Param1: test1
Param2: test2
Param3: test3

Example

Going by this comment code:

foreach $rows as $row .. .. id; ?>" href="program/details_program/id; ?>"> program_title; ?> page detail.php $id = $this->uri->segment(2); $query = $this->db->get_where('programs', array('id' => $id));

it looks like you have a program controller with a details_program method that you are linking to and this is where you want a different solution to uri->segment . If this is the case, something like this would work with a URL like http://example.com/program/program_details/123 :

class Program extends CI_Controller{

    function program_details($id = NULL){
        $query = $this->db->get_where('programs', array('id' => $id));
    }

}

If this isn't what you want, please update the question with all of the relevant (properly formatted) code
