在自制的PHP MVC框架中呈现视图文件

问题描述：

I've developed My Own MVC Framework using php. I call view files in controller like:

include('../view/home.php');

but I want to use it like:

$this->view('home');

How can I define common function for that where I can just pass view name i.e home only and it will do include view file without passing the full file path?

No one could answer you without seeing your codes really. But this should be my approach. You should have a class that all your controllers extend. Lets say that you have class Controllers and all your controllers extend it.

Then you may have a method inside the class named view($view_name).

public function view($view_name){
   include $some_path . '/' . $view_name . '.php';
}

then whenever you call view by $this->view it will include the view if it exists. This is not the best approach and I did not test the code. I just wanted to show you the path

I don't know Your MVC file/directory/namespace and etc structure.

But for beginner who tries to learn MVC and Frameworks by "reinventing wheel" (: I can give such example:

1) Create common abstract controller class in app/controllers folder:

namespace App\Controllers;

abstract class Controller {

  public function view($name) {
    include(__DIR__.'/../views/'.$name.'.php';
  }

}

2) Create Your own controller i.e. PagesController and use it:

namespace App\Controllers;

class PagesController extends Controller {

  public function home() {
    $this->view('home');
  }
}

p.s. You may omit namespace-ing, abstract word depending on autoloader logic
