Controller

public function get_date_statistik() {
    for($i = 1; $i <=  date('t'); $i++) {                       
        foreach($this->my_model->get_data() as $row)
        {
            $data[] = array(
                'date_on_month' => str_pad($i, 2, '0', STR_PAD_LEFT),
                'total' => $row['total']
              );                    
        }   
    }
    echo json_encode($data);

}

Models

function get_data() {
        $sql = "SELECT count(ip) as total FROM my_table WHERE DATE(date) = date('d') ";
        return $this->db->query($sql)->result_array();  
    }

Result

[{"date_on_month":"01","total":"0"},{"date_on_month":"02","total":"0"},{"date_on_month":"03","total":"0"} .........]

Your controller will be as :

public function get_date_statistik() {
    for($i = 1; $i <=  date('t'); $i++) {
        $date_string = date('Y')."-".date('m')."-".$i;
        foreach($this->my_model->get_data($date_string) as $row)
        {
            $data[] = array(
                'date_on_month' => str_pad($i, 2, '0', STR_PAD_LEFT),
                'total' => $row['total']
              );                    
        }   
    }
    echo json_encode($data);

}

Your model should be like:

function get_data($date_string) {
        $sql = "SELECT count(ip) as total FROM my_table DATE_FORMAT( `date` , '%m-%d' ) = DATE_FORMAT($date_string, '%m-%d' )";
        return $this->db->query($sql)->result_array();  
    }
