Autoloading a class in Symfony 2.1

Question

I'm porting a Symfony 1.2 project to Symfony 2.x. I'm currently running the latest 2.1.0-dev release.

From my old project I have a class called Tools which has some simple functions for things like munging arrays into strings and generating slugs from strings. I'd like to use this class in my new project but I'm unclear how to use this class outside of a bundle.

I've looked at various answers here which recommend changing app/autoload.php but my autoload.php looks different to the ones in the answers, maybe something has changed here between 2.0 and 2.1.

I'd like to keep my class in my src or app directories as they're under source control. My vendors directory isn't as I'm using composer to take care of that.

Any advice would be appreciated here.

Another way is to use the /app/config/autoload.php:

<?php

use Doctrine\Common\Annotations\AnnotationRegistry;

$loader = require __DIR__.'/../vendor/autoload.php';
$loader->add( 'YOURNAMESPACE', __DIR__.'/../vendor/YOURVENDOR/src' );


// intl
if (!function_exists('intl_get_error_code')) {
    require_once  _DIR__.'/../vendor/symfony/symfony/src/Symfony/Component/Locale/Resources/stubs/functions.php';

    $loader->add('', __DIR__.'/../vendor/symfony/symfony/src/Symfony/Component/Locale/Resources/stubs');
}

AnnotationRegistry::registerLoader(array($loader, 'loadClass'));

return $loader;

Just replace YOURNAMESPACE and YOURVENDOR with your values. Works quite well for me, so far.

You're correct, I stumbled upon the changes in autoload from 2.0 to 2.1. The above code works fine with the latest version, to which I upgraded my project ;-)
