下面是一个超级简单的MVC结构实现，甚至连数据源都用了一个内置的固定数组，虽然简单，但其实众多的PHP Framework核心实现的思想应该和这个是差不多的，只不过一些framework提供了更多的方便开发者使用的工具，我也想自己来实现一个PHP的 框架，目前正在着手策划中，也希望自己能够从框架的开发中学习到更多的PHP设计思想和方法。

Controller.php

include 'Model.php';
include 'View.php';

class Controller {
    private $model     = '';
    private $view     = '';
   
    public function Controller(){
        $this->model    =    new Model();
        $this->view        =    new View();
    }
   
    public function doAction( $method = 'defaultMethod', $params = array() ){
        if( empty($method) ){
            $this->defaultMethod();
        }else if( method_exists($this, $method) ){
            call_user_func(array($this, $method), $params);
        }else{
            $this->nonexisting_method();
        }
    }
   
    public function link_page($name = ''){
        $links = $this->model->getLinks();
        $this->view->display($links);
       
        $result = $this->model->getResult($name);
        $this->view->display($result);
    }
   
    public function defaultMethod(){
        $this->br();
        echo "This is the default method. ";
    }
   
    public function nonexisting_method(){
        $this->br();
        echo "This is the noexisting method. ";
    }
   
    public function br(){
        echo "<br />";
    }
}

$controller = new Controller();
$controller->doAction('link_page', 'b');
$controller->doAction();

Model.php

Code
class Model {
    private $database = array(
        "a"    =>    "hello world",
        "b"    =>    "ok well done",
        "c"    =>    "good bye",
    );
   
    //@TODO connect the database
   
    //run the query and get the result
    public function getResult($name){
        if( empty($name) ){
            return FALSE;
        }
       
        if( in_array($name, array_keys( $this->database ) ) ){
            return $this->database[$name];
        }
    }

    public function getLinks(){
        $links = "<a href='#'>Link A</a>&nbsp;&nbsp;";
        $links.= "<a href='#'>Link B</a>&nbsp;&nbsp;";
        $links.= "<a href='#'>Link C</a>&nbsp;&nbsp;";
       
        return $links;
    }
}

View.php

class View {
   
    public function display($output){
//        ob_start();
       
        echo $output;
    }
   
}
