Organize routes into separate files not working properly in Slim

问题

This is my Index.php file:

use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;
require '../vendor/autoload.php';
require '../src/config/db.php';

$app = new \Slim\App;
//User Routes
require '../src/routes/users.php'; // This not working
require '../src/routes/org.php'; // Only This working

$app->run();

.htaccess file

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ index.php [QSA,L]

When there is only one require file it's working fine but when adding two or multiple files then only last one working and others giving page not found error. I'm new in slim and PHP so I have no idea what's wrong.

users.php

<?php
/**
 * User: y34h1a

 * Time: 3:47 AM

        $users['users'] = $stmt->fetchAll(PDO::FETCH_OBJ);

回答1:

Okay, your problem is that you basically create three instances of application: one in index.php, one in users.php, one in org.php.

Application instance is created by

$app = new \Slim\App;

And that application is launched by $app->run.

In index.php you have $app, which is overriten by $app in users.php, then overwritten by $app in org.php.

This is the reason why require '../src/routes/users.php'; seems to be ignored - it's declaring $app, adds routes and in the next file you overwrite $app and add routes.

To fix this, simply remove

$app = new \Slim\App;

from everywhere but index.php.
