问题从Slim 2开始

Question

I'm developing a web service using Slim Framework 2, it's the first time I use php. I'm having an issue with the Slim object:

There's my code:

require 'db.php';
require 'vendor/slim/slim/Slim/Slim.php';
echo 'require ok';
$app = new vendor/slim/slim/Slim();
echo '$app ok';

The 'require' lines are ok. But he $app line doesn't work I use the same path to the Slim.php file and also I've tryed to use this path:

$app = /slim/Slim();

The first echo is executing but the second one is not working. My ws.php file is on the same directori as the vendor folder:

vendor/slim/slim/Slim/
├── Environment.php
├── Exception
│   ├── Pass.php
│   └── Stop.php
├── Helper
│   └── Set.php
├── Http
│   ├── Cookies.php
│   ├── Headers.php
│   ├── Request.php
│   ├── Response.php
│   └── Util.php
├── Log.php
├── LogWriter.php
├── Middleware
│   ├── ContentTypes.php
│   ├── Flash.php
│   ├── MethodOverride.php
│   ├── PrettyExceptions.php
│   └── SessionCookie.php
├── Middleware.php
├── Route.php
├── Router.php
├── Slim.php
└── View.php

Is $app = new vendor/slim/slim/Slim(); correct? I'm lost about this topic.

Solved using Frank Martin solution:

require 'vendor/autoload.php';
$app = new \Slim\App;

Instead:

require 'vendor/slim/slim/Slim/Slim.php';
$app = new vendor/slim/slim/Slim();

Make sure you've installed the composer dependencies then use this instead.

require 'vendor/autoload.php';
$app = new \Slim\App;
