如何在没有codeIgniter MVC框架的情况下使用数据库codeigniter类？

Question

My goal is to use the CodeIgniter database Class, but inside a plain PHP script. I don't want to use MVC structure for this.

Can I use this database class WITHOUT using the CodeIgniter MVC pattern?

If yes, how?

Answer 1

Please follow below steps to integrate Codeigniter DB Active Record

1. Download latest codeigniter from https://codeigniter.com/

2. Copy below files

    application/config/config.php application/config/database.php system/database/* system/core/Common.php system/core/Exceptions.php system/core/Log.php 

   

The directory structure is as above

3. Add database connection details in application/config/database.php

4. Create db connection(connector.php) file

    <?php defined('DS') OR define('DS', DIRECTORY_SEPARATOR); defined('EXT') OR define('EXT', '.php'); defined('ENVIRONMENT') OR define('ENVIRONMENT', 'development'); $dir_path = dirname(__FILE__) . DS; defined('BASEPATH') OR define('BASEPATH', $dir_path . 'system' . DS); defined('APPPATH') OR define('APPPATH', $dir_path . 'application' . DS); function getDBConnector(){ include_once(BASEPATH . "core/Common.php"); include_once(BASEPATH . "core/Exceptions.php"); require_once(BASEPATH . 'database/DB' . EXT); $conn = & DB(); return $conn; } $db = getDBConnector(); print_r($db->get('users')->result_array()); 

5. Now include connector.php in your project and access DB object :)
