使用此路由的我的404文件不存在的重定向页

Question

我是新来的，对不起，如果有问题。我在某个地方找到了这条路线，它做得很好，但是当我去Local -Host/blablabal时，只有一个白页，并且不会重定向到我的404错误文件

index.php file.php

<?php

include 'route.php';

$route = new Route();

$route->add('/', function() {
    require('config/home_l.php');
});

$route->add('pretraga', function() {
    require('config/pretraga.php');
});

$route->submit();

file.php file.php
