php - fatal error : Uncaught Error: Class not found in dynamic variable namespace

Question

我有这个主 Controller :

namespace App\Core;
/**
* Controller class
*/

class Controller
{
    /** @var View View The view object */
    public $View;
    public $templates;
    /**
     * Construct the (base) controller. This happens when a real controller is constructed, like in
     */
    public function __construct()
    {

    }

    public function loadModel($name) {

        $path = '\\App\\Front\\Model\\'.$name; // Not Work

        //$this->model = new \App\Front\Model\IndexModel(); Work

        $this->model = new $path;

        return $this->model;

    }
}

在 IndexController 我有:

namespace App\Front\Controller;

use App\Front\Model\IndexModel;

class IndexController extends \App\Core\Controller {

    public function index(){
        $this->loadModel('IndexModel()')->test();
    }
}

现在在行动中我看到错误:

Fatal error: Uncaught Error: Class '\App\Front\Model\IndexModel()' not found in /Applications/MAMP/htdocs/mvc/application/Core/Controller.php:64

如何修复错误？

Answer 1

您需要删除 ()从字符串:

$this->loadModel('IndexModel')->test();

没有必要 ()创建没有参数的新实例时。如果你确实想要它，或者你想传递一些参数，你需要在实例化的变量之后添加它们:

new $path('someArgument');
