在建構函式中使用註冊一個會在php中止時執行的函式register_shutdown_function(), TP5框架中使用

$request = \think\Request::instance();
        if ($request->controller() == "School" && $request->action() == "schoolarc") {
            register_shutdown_function(function() {
                BM('Errorlog')->uploadLog();
            });
        }

<?php
use think\Db;
