深入浅析用PHP实现MVC

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