Call類

Question

我有兩個班，路由器和森美，兩者都是在不同的命名空間，但我需要調用Router類薩米類，但它給我一個錯誤

Notice: Undefined index: GlobeAPI\Classes\Router\Sammy in /opt/lampp/htdocs/web/globeapi/GlobeAPI/Classes/Autoloader/Autoloader.php on line 151 

錯誤及其自我現在是irelavent，我不知道如何正確調用Sammy類。

這裏是Router.php代碼

namespace GlobeAPI\Classes\Router; 
class Router 
{ 
    public static $call = null; 

    function __construct() 
    { 

    } 

    public static function get($route, $call) { 
     self::$call = $call; 
     Sammy::process($route, 'GET'); 
    } 

    public static function post($route, $call) { 
     self::$call = $call; 
     Sammy::process($route, 'POST'); 
    } 

    public static function put($route, $call) { 
     self::$call = $call; 
     Sammy::process($route, 'PUT'); 
    } 

    public static function delete($route, $call) { 
     self::$call = $call; 
     Sammy::process($route, 'DELETE'); 
    } 

    public static function ajax($route, $call) { 
     self::$call = $call; 
     Sammy::process($route, 'XMLHttpRequest'); 
    } 

    public static function dispatch() 
    { 

     $call   = explode('#', self::$call); 
     $controller  = $call[0]; 
     $function  = $call[1]; 

     self::loadController($controller); 
     self::loadFunction($controller, $function); 
    } 

    public static function loadController($controller) 
    { 
     $path = APP_PATH . 'controllers/' . ucfirst($controller) . '.php'; 
     if(file_exists($path)) 
     { 
      include_once($path); 
     }else 
     { 
      return false; 
     } 
    } 

    public static function loadFunction($controller, $function) 
    { 

     $cls = ucfirst($controller); 

     if(class_exists($cls)) 
     { 
      $tmp = new $cls(); 

      if(is_callable(array($tmp, $function))) 
      { 
       $tmp->$function(); 
      }else 
      { 
       echo 0; 
      } 
     } 
    } 
} 

這裏是Sammy.php代碼

由於這兩個文件不在同一個命名空間，你必須指定你想要哪一類通過添加單詞use，然後在您的Router.php上的名稱空間聲明之後添加完整的類命名空間：

use GlobeAPI\Classes\Sammy\Sammy; 

您可以在documentation上看到更多解釋。
