Answer 1

I have found the solution by doing the this.

<?php
require "Slim/Slim.php";

\Slim\Slim::registerAutoloader();

// create new Slim instance
$app = new \Slim\Slim();

Answer 2

Use this code after importing Slip.php

use \Slim\Slim AS Slim;
$app = new Slim();

Answer 3

as stated in Slim documentation , you need to call autoloader:

<?php
require 'Slim/Slim.php';
\Slim\Slim::registerAutoloader();
