Redundant data control in Controller, How!!!

[eluser]Unknown[/eluser]
I am new to CI,

This is my code

Code:

<?php
class Home extends Controller {
    
    /**
     *
     * Enter description here ...
     */
    function __construct() {
        parent::Controller();
    }
    
    /**
     *
     * Enter description here ...
     */
    function index() {
        
        $data = "";
        $data['view_pagetitlebar'] = "Welcome | Muhammad Ahmed";
        $data['view_metadata'] = "metadata";
        $data['view_stylesheet'] = "css style sheet";
        $data['view_navlinks'] = "nav links";
        $data['view_pagetitle'] = "asd";
        
        $data['view_contents_left'] = "Left side content";
        $data['view_footer'] = "Footer";
        
        
        $data['view_contents_right'] = "This is the home page";
        
        $this->load->view('view_main', $data);
        
    }
    
    /**
     *
     * Enter description here ...
     */
    function about() {
        
        $data = "";
        $data['view_pagetitlebar'] = "Welcome | Muhammad Ahmed";
        $data['view_metadata'] = "metadata";
        $data['view_stylesheet'] = "css style sheet";
        $data['view_navlinks'] = "nav links";
        $data['view_pagetitle'] = "asd";
        
        $data['view_contents_left'] = "Left side content";
        $data['view_footer'] = "Footer";
        
        
        $data['view_contents_right'] = "This is the about page";
        
        $this->load->view('view_main', $data);
        
    }
}

we can see each time maximum data remains the same, only 'view_contents_right' is different in each function.

If i made a new function or any new controller i need to paste all the data again with update 'view_contents_right' data...
Can we controller this redundant data..

Any link, or any thing that can help me...

Thanks,
Muhammad Ahmed
