Class 'Proxy\Factory' not found PHP error although file exists - php

Question

I downloaded this lib, extracted it and uploaded it to my php webspace: https://github.com/jenssegers/php-proxy
Also, I added a new index.php file with this content from the example included to the lib archive:
<?php
use Proxy\Factory;
use Proxy\Response\Filter\RemoveEncodingFilter;
use Symfony\Component\HttpFoundation\Request;
require 'vendor/autoload.php';
// Create the proxy factory.
$proxy = Factory::create();
// Add a response filter that removes the encoding headers.
$proxy->addResponseFilter(new RemoveEncodingFilter());
// Create a Symfony request based on the current browser request.
$request = Request::createFromGlobals();
// Forward the request and get the response.
$response = $proxy->forward($request)->to('http://example.com');
// Output response to the browser.
$response->send();
?>
The file structure looks like this (collapsed):
Expanded:
But when I run the script, I get this error:
Fatal error: Class 'Proxy\Factory' not found in index.php on line 10
Line 12 would be this:
$proxy = Factory::create();
Why does this happen? Shouldn't use Proxy\Factory; properly include the file Factory.php?
Update: The content of autoload.php is this:
<?php
// autoload.php #generated by Composer
require_once __DIR__ . '/composer' . '/autoload_real.php';
return ComposerAutoloaderInit60f173139b462a85925faf1b40913ce6::getLoader();

I finally got it to work. I had totally messed up the Symfony project structure, so here is what I did to get it to work:
Run in shell (on Mac OS X):
$ symfony new proxy 2.7
$ cd proxy
$ curl -sS https://getcomposer.org/installer | php
$ php composer.phar require jenssegers/proxy
$ sudo cp /etc/php.ini.default /etc/php.ini
In /etc/php.ini search for timezone and remove the colon in front. Then set date.timezone = "Europe/Berlin".
Then I edit this file: src/AppBundle/Controller/DefaultController.php and add my code:
<?php
namespace AppBundle\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Proxy\Factory;
use Proxy\Response\Filter\RemoveEncodingFilter;
require '/Users/me/dev/symphony/proxy/vendor/autoload.php';
class DefaultController extends Controller
{
/**
* #Route("/", name="homepage")
*/
public function indexAction(Request $request)
{
// replace this example code with whatever you need
/*
return $this->render('default/index.html.twig', array(
'base_dir' => realpath($this->container->getParameter('kernel.root_dir').'/..'),
));
*/
// Create the proxy factory.
$proxy = Factory::create();
// Add a response filter that removes the encoding headers.
$proxy->addResponseFilter(new RemoveEncodingFilter());
// Create a Symfony request based on the current browser request.
$request = Request::createFromGlobals();
// Forward the request and get the response.
$response = $proxy->forward($request)->to('http://example.com');
// Output response to the browser.
$response->send();
}
}
Then just run the server:
$ php app/console server:run
And open localhost:8000.

Try moving index.php one level up in directory structure: require vendor/autoload.php inside vendor dir looks too strange, it is not very likely you (and anyone) would have vendor directory inside vendor directory
