直接使用库而不是 Symfony2 中的包 [英] Working directly with libraries instead of bundles in Symfony2
问题描述
如何在现有的 Symfony2 项目中直接使用库.例如，我正在尝试添加 faker 库.我通过 composer 安装了它，但我不知道如何以及在哪里放置我需要的代码.
How can I use a library directly inside an existing Symfony2 project. I am, for instance, trying to add the faker library. I installed it via composer but I don't know how and where to put the code I need.
根据文档:
// require the Faker autoloader
require_once '/path/to/Faker/src/autoload.php';
// alternatively, use another PSR-0 compliant autoloader (like the Symfony2 ClassLoader for instance)
自动加载器的简单解释是什么?如何在没有捆绑的情况下直接使用库?库是否需要具有 autoload.php 文件以便它可以集成到 php 项目中?上面的代码放在哪里?
What is a simple explanation of auto loader?
How to use a library directly without a bundle?
Is it a requirement for a library to have an autoload.php file so that it can be integrated inside a php project?
Where to put the above code?
有任何链接可以为新手解释这些概念吗?非常感谢您平时的指导.

推荐答案
您无需进行任何配置.Faker 库是 PSR-4(参见 composer.json，第 23 行) 兼容所以只需安装它(通过 composer)并使用正确的命名空间.Symfony 自动加载 PSR-4/PSR-0 库/组件.像这样:
You do not need to config nothing. Faker library is PSR-4 (see composer.json, line 23) compliant so just install it (through composer) and use the proper namespace. Symfony automatically loads PSR-4 / PSR-0 libraries/components. Like this:
<?php # src/AppBundle/Controller/DefaultController.php
namespace AppBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Faker;
class DefaultController extends Controller
{
public function indexAction()
{
$faker = Faker\Factory::create();
var_dump($faker); die;
// ...
}
}
