PHP路由不重定向

我正在try 用PHP创建简单的路由，但我不明白为什么它不能正确地重定向.

所以我的设置的工作方式是我有3条路由

• 回家路由"/"
• 用户路径"/USER"
• ID为"/USER？ID={[0-9]}"的用户

当我重定向到"/"ROUTE时，这是打印的内容.

/ Path / traversed

不过，我想把这个打印出来.

/ Succesfuly navigated to / Path / traversed

然而，所有这些都不适用于任何其他路径. 这是我重定向到"/USER"时得到的结果

/user Not Found

这就是我想要呈现的东西.

/user Succesfuly navigated to /user Path /user traversed

这是我为Router.php编写的脚本

<?php 

    class Router{

        public function get($route, $callback){

            $path = $this->getPath(); //GET PATH for ex. /users/user
            $query = $this->getQuery(); //GET QUERY for ex. ?id=15

            print($_SERVER['REQUEST_URI']);
            echo " ";

            //IF USER IS NAVIGATING TO ROUTE THAT DOESN'T EXIST PRINT "NOT FOUND"
            if($path != $route){
                $this->notFound(); 
            }

            if($path == $route){

                //IF CALLBACK IS A STRING DO SOMETHING WITH IT
                if(is_string($callback)){
                    echo "Succesfuly navigated to {$route}";
                    exit();
                }
                
                //EXECUTE CALLBACK FUNCTION
                echo call_user_func($callback);
                exit();
            }
          
        }

        //GET PATH FROM URI
        private function getPath(){
            $path = $_SERVER['REQUEST_URI'] ?? '/';
            $paramPosition = strpos($path, "?");

            if($paramPosition === false){
                return $path;
            }

            $path = substr($path, 0, $paramPosition);
            return $path;
        }

        //GET QUERY STRING ?id=15
        private function getQuery(){

            $path = $_GET;
            if(count($path) == 1){
                return $path;
            }
 
            return $path;
        }


        //404 TEXT
        private function notFound(){
            http_response_code(404);
            echo "Not Found";
            exit();
        }
    }
?>

这是我的index.php

<?php

    include_once './core/Router.php';

    $router = new Router();

    $router->get("/", function() {
        echo "Path / traversed";
    });

    $router->get("/user", function() {
        echo "Path /user traversed";
    });

    $router->get("/user?id={[0-9]}", function(){
        echo "Path /user?id={[0-9]} traversed";
    });


?>
