php - 如何更改类变量并保存此变量

Question

路由/web.php

Route::post("/setBestBook",function(Request $request){
    Books::setBestBook($request->book);
    return "Your best book have been added";
});


Route::get("/BestBook",function(){
    return (Books::getBestBook().gettype(Books::getBestBook()));
});

书籍类：

<?php

namespace App;

class Books{

    public static $BestBook;

        static function setBestBook($book){

        static::$BestBook=$book;

    }

    static function getBestBook(){

        return static::$BestBook;

    }

} 

我想当有人发送喜欢的书时，服务器保存书名，但不在数据库中
