Question

我在自己的项目中遇到了一些麻烦。我编写了一个简单的考试系统，为了方便起见，我使用了Late Static Bindings。我有下一个代码：

<?php
class Controler {
    public $dir;
    public $name;
    public $file;

    public function __construct( $dir = ST_CONTROL_DIR ) {
        $this->dir = $dir;
    }

    public function __call( $name, $arguments = array() ) {
        $this->name = &$name;
        $this->file = $this->dir . $this->name . '.php';

        var_dump(get_called_class());

        $result = $this->controler_include( ... $arguments );
        return $result;
    }
    public static function __callStatic( $name, $arguments = array() ) {
        var_dump(get_called_class());
        $obj = new static();
        return $obj->$name( ... $arguments );
    }
    private final function controler_include(){
        return include $this->file;
    }
}

class Router extends Controler {
    public function __construct(){
        parent::__construct(ST_ROUTER_DIR);
    }
}


class Routing {
    protected $action;
    protected $params;
    protected $reffer;

    static public function initialize(){
        global $ROUTER;
        $ROUTER = new self;
    }
    static public function process(){
        global $ROUTER;
        xdebug_start_trace( ST_DIR.'trace' );
        if($ROUTER->action == 'api'){
            $ROUTER->action = array_shift( $ROUTER->params );
            trig( 'router_process_api_before' );
            return Api::{ $ROUTER->action }( ... $ROUTER->params );
        } else {
            trig( 'router_process_before' );
            return Router::{$ROUTER->action}( ... $ROUTER->params );
        }
        xdebug_stop_trace();
    }
}

我的方法用分隔文件编写。此外，类Router是Controler的子类，并且仅由包含其文件方法的文件夹不同。

我执行GET-query / login，类路由使用以下代码执行构建此页面：

<?php
reg( 'view_header_css', function(){
    ?><link href="<?php echo ST_CSS_PATH ?>login.css" rel="stylesheet"><?php
});

Controler::{'message'}();

我想在这里调用控制器类的静态方法。我的结果：

string 'Router' (length=6)
string 'Router' (length=6)

如果我打电话给View :: {＆＃39;消息＆＃39;} - 所有＆＃39;是正确的。（View是Controler的孩子）

现在我的问题：当我调用父类的静态方法时，有人可以解释为什么PHP执行子类的非静态方法吗？
