如何从codeigniter的控制器打开核心php中的视图

I have my php project in following structure

> myProject  
   ->memberList.php  
   ->memberEntry.php  
   ->ci
       ->application
           ->controller             
                ->siteController        
           ->model      
           ->view

I am using both core php and Codeigniter framework for my project named 'myProject.' I have added CI framework inside folder named 'ci'. Most of the code is in core php and for some forms only i have use ci framework. I have to open a form named memberEntry.php from siteController.How can this be done? My controller code is like this:

public function auditDetails(){
    ..........
    $this->load->view('../../../memberEntry', $data);
}

Assuming this is your structure:

go in to index.php and change the following variables

/*
 *---------------------------------------------------------------
 * SYSTEM DIRECTORY NAME
 *---------------------------------------------------------------
 *
 * This variable must contain the name of your "system" directory.
 * Set the path if it is not in the same directory as this file.
 */
    $system_path = 'ci/system';

/*
 *---------------------------------------------------------------
 * APPLICATION DIRECTORY NAME
 *---------------------------------------------------------------
 *
 * If you want this front controller to use a different "application"
 * directory than the default one you can set its name here. The directory
 * can also be renamed or relocated anywhere on your server. If you do,
 * use an absolute (full) server path.
 * For more info please see the user guide:
 *
 * https://codeigniter.com/user_guide/general/managing_apps.html
 *
 * NO TRAILING SLASH!
 */
    $application_folder = 'ci/application';

/*
 *---------------------------------------------------------------
 * VIEW DIRECTORY NAME
 *---------------------------------------------------------------
 *
 * If you want to move the view directory out of the application
 * directory, set the path to it here. The directory can be renamed
 * and relocated anywhere on your server. If blank, it will default
 * to the standard location inside your application directory.
 * If you do move this, use an absolute (full) server path.
 *
 * NO TRAILING SLASH!
 */
    $view_folder = './';

then you can just load view as normal $this->load->view('welcome_message');

I would also suggest not using camelCase definitions for files and switch over to Something_more_codeigniter_friendly.php. This is required for controllers.
