시작하기

* 프로그램의 첫 단추 hello world로 시작해 봅시다. 
<?php
/**
 * Hello World
 *
 * Created on 2014. 10. 13.
 * @author 불의회상 <hoksi2k@hanmail.net>
 * @version 1.0
 */
class Hello_world extends CI_Controller {
	public function index() {
		echo 'Hello World!';
	}

}

* World가 지겹다면 Controller로 바꿔 봅시다.

갑자기 $name 이 생기기는 했지만 신경쓰지 맙시다.

<?php
/**
 * Hello World
 *
 * Created on 2014. 10. 13.
 * @author 불의회상 <hoksi2k@hanmail.net>
 * @version 1.0
 */
class Hello_controller extends CI_Controller {
	public function index($name = 'Controller') {
		echo 'Hello ' . $name . '!';
	}

}


* 내 이름이 안나오니 별로네요.

'hoksi' 가 출력되도록 수정해 봅시다. 

하지만 프로그램을 수정하지는 않을겁니다. 이럴때를 위해서 $name 을 추가 한거니까요. ^^

대신 아래 처럼 URL에 인자값을 넘겨주면 됩니다.

갑자기 index 가 붙기는 했지만 출력은 잘 된답니다.

ex> hello_controller/index/hoksi

<?php
/**
 * Hello World
 *
 * Created on 2014. 10. 13.
 * @author 불의회상 <hoksi2k@hanmail.net>
 * @version 1.0
 */
class Hello_controller extends CI_Controller {
	public function index($name = 'Controller') {
		echo 'Hello ' . $name . '!';
	}

}
* _remap을 사용해 봅시다 
<?php
/**
 * Hello Remap
 *
 * Created on 2014. 10. 13.
 * @author 불의회상 <hoksi2k@hanmail.net>
 * @version 1.0
 */
class Hello_remap extends CI_Controller {
	public function _remap($name = 'World') {
		echo 'Hello ' . $name . '!';
	}

}

* _remap을 사용하면 index를 지울 수 있습니다.

아래처럼요.. ^^

ex> hello_remap/hoksi

 

<?php
/**
 * Hello Remap
 *
 * Created on 2014. 10. 13.
 * @author 불의회상 <hoksi2k@hanmail.net>
 * @version 1.0
 */
class Hello_remap extends CI_Controller {
	public function _remap($name = 'World') {
		echo 'Hello ' . $name . '!';
	}

}
* 모델을 사용해 볼까요? 
<?php
/**
 * Hello Model
 *
 * Created on 2014. 10. 13.
 * @author 불의회상 <hoksi2k@hanmail.net>
 * @version 1.0
 */
class Hello_model extends CI_Controller {
	public function index() {
		$this->load->model('mvc_sample/hello_m');
		
		echo 'Hello ' . $this->hello_m->get_name() . '!';
	}

}

<?php
/**
 * Hello_m
 *
 * Created on 2014. 10. 13.
 * @author 불의회상 <hoksi2k@hanmail.net>
 * @version 1.0
 */
class Hello_m extends CI_Model {
	public function __construct()
	{
		parent::__construct();
	}
	
	public function get_name()
	{
		return 'Model';
	}
}
* 뷰도 사용해 봅시다. 
<?php
/**
 * Hello View
 *
 * Created on 2014. 10. 13.
 * @author 불의회상 <hoksi2k@hanmail.net>
 * @version 1.0
 */
class Hello_view extends CI_Controller {
	public function index() {
		$this->load->view('mvc_sample/hello_view');
	}

}

Hello view!
* 간단한 블러그도 만들어 봅시다.
