所以这是我的mixin课程：

class AisisCore_Loader_Mixins {

    private $_classes;

    private $_class_objects = array();

    private $_methods = array();

    public function __construct(){
        $this->init();
    }

    public function init(){}

    public function setup($class){
        if(!is_array($class)){
            throw new AisisCore_Loader_LoaderException('Object passed in must be of type $class_name=>$params.');
        }

        $this->_classes = $class;
        $this->get_class_objects();
        $this->get_methods();    
    }

    public function get_class_objects(){
        foreach($this->_classes as $class_name=>$params){
            $object = new ReflectionClass($class_name);
            $object_name = get_class($object);
            $this->_class_objects[$object->name] = $object->newInstanceArgs($params);
        }
    }

    public function get_methods(){ 
        foreach($this->_class_objects as $class_object_name => $class_object){
            $this->_methods[$class_object_name] = get_class_methods($class_object);
        }

        return $this->_methods;
    }

    public function __call($name, $param = null){
        foreach($this->_methods as $class_name=>$methods){
            foreach($methods as $method){
                if($name === $method){
                    return $this->isParam($class_name, $method, $param);
                }
            }
        }

        throw new AisisCore_Loader_LoaderException("Method: " .$name. 
                            " does not exist or it's access is not public");
    }

    private function isParam($class_name, $method, $param){
        if($param != null){
            call_user_func(array($class_name, $method), $param);
        }else{
            call_user_func(array($class_name, $method));
        }        
    }
}

非常简单的东西，加载一组类，允许你调用它们的函数等等，但是我们有一个新的问题。似乎传递给它的类被实例化为静态，因此他们的方法不能使用$this->他们使用self::这是错误的。

让我们看一下这一切如何运作的例子：

class BaseBridge extends AisisCore_Loader_Mixins{

    public function __construct(){ 
        parent::construct();

        $this->setup(array('ClassB' => array()));
    }
}

让我们定义ClassB

class ClassB{

    public function __construct(){}

    public function some_method(){
        $this->_some_private_method();
    }

    private function _some_private_method(){}
}

非常基本的东西，所以让我们把它挂钩在ClassA

class ClassA extends BaseBridge{

    public function __construct(){ 
        parent::__construct(); 
        $this->some_method();
    }
}

快速审核：我们有一个核心类ClassA扩展了BaseBridge，这是我们在一个或多个（意味着要与更多用户）类之间的桥接类ClassA延伸自。在这种情况下，为了简单起见，仅从ClassB延伸。

问题是什么？请参阅ClassB中的信息：$this->_some_private_method(); ya是否会出现严重的灾难性故障。 为什么？因为我收到了错误：Using $this when not in object context让我如此困惑，所以我将其更改为：self::$_some_private_method();并且它就像魅力一样。

为什么呢？我需要更改或修改哪些内容才能使$this可以在通过mixin类实例化的类中使用？

因此，经过一些细微的修改，我成功地完成了这项工作。我怎么不相信具有多个参数的函数可以工作 - 反馈赞赏。

class AisisCore_Loader_Mixins {

    private $_classes;

    private $_class_objects = array();

    private $_methods = array();

    public function __construct(){
        $this->init();
    }

    public function init(){}

    public function setup($class){
        if(!is_array($class)){
            throw new AisisCore_Loader_LoaderException('Object passed in must be of type $class_name=>$params.');
        }

        $this->_classes = $class;
        $this->get_class_objects();
        $this->get_methods();    
    }

    public function get_class_objects(){
        foreach($this->_classes as $class_name=>$params){
            $object = new ReflectionClass($class_name);
            $this->_class_objects[$object->name] = $object->newInstanceArgs($params);
        }
    }

    public function get_methods(){ 
        foreach($this->_class_objects as $class_object_name => $class_object){
            $this->_methods[$class_object_name] = get_class_methods($class_object);
        }

        return $this->_methods;
    }

    public function __call($name, $param = null){
        foreach($this->_methods as $class_name=>$methods){
            foreach($methods as $method){
                if($name === $method){
                    return $this->_is_param($class_name, $method, $param);
                }
            }
        }

        throw new AisisCore_Loader_LoaderException("Method: " .$name. 
                            " does not exist or it's access is not public");
    }

    private function _is_param($class_name, $method, $param){
        if($param != null){
            $this->_param_is_array($class_name, $method, $param);
        }else{
            call_user_func(array($this->_class_objects[$class_name], $method));
        }        
    }

    private function _param_is_array($class_name, $method, $param){
        if(is_array($param)){
            call_user_func_array(array($this->_class_objects[$class_name], $method), $param);
        }else{
          call_user_func(array($this->_class_objects[$class_name], $method, $param));  
        }        
    }
}

现在，由此类注册的类中的函数可以使用$this->。

问题是我不确定基于多个参数的函数是否真的有用。
