Question

当前，我正在从一个非命名空间的php文件中调用一个命名空间的函数。

我的功能定义在：

ReservationValidation.php

namespace App\Reservation;

use Slim\Http\{Request, Response};
use Swaggest\JsonSchema\Schema;

function validateReservationPatch(Request $request, Response $response, callable $next)
{
    try {
        $schema = Schema::import(__DIR__ . '/schemas/patch.json');
        $schema->in(json_decode($request->getBody()));
    } catch(Exception $e) {
        return $response->withStatus(400);
    }

    return $next($request, $response);
}

我从以下位置调用它：

route.php

<?php

use App\Auth\Authenticate;
use function App\Reservation\validateReservationPatch;

$reservationPath = '/reservations';

$app->add(new Authenticate())->add(function ($request, $response, $next) {
    validateReservationPatch($request, $response, $next);
})->patch($reservationPath, 'ReservationController:updateReservation');

我遇到了这个错误：

Slim Application Error
The application could not run because of the following error:

我可以调用命名空间的类，但不能调用该函数。有想法吗？

命名函数调用未定义的函数
