如何在Symfony Bundle中包含自定义类？
[英]How to include a custom class in a Symfony Bundle?
I have a Symfony bundle where I will have to use a custom class. This class does not have to be accessible from all the website, but just in a controller of this bundle. I have seen a few solutions relative to the vendors, but this is quite heavy and not necessary in my case. Does someone have a simpler solution?
我有一个Symfony包，我将不得不使用自定义类。此类不必从所有网站访问，而只能在此捆绑包的控制器中访问。我已经看到了一些与供应商相关的解决方案，但这很重，在我的情况下不是必需的。有人有更简单的解决方案吗？

Class must be created in Acme\Bundle\Model namespace and folder, not \Class! Who says this?!
必须在Acme \ Bundle \ Model命名空间和文件夹中创建类，而不是\ Class！谁说这个？！
// ../src/Acme/Bundle/Model/Utility.php
<?php namespace Acme\Bundle\Model;
class Utility:
..
Using in controllers:
在控制器中使用：
<?php ..
use Acme\Bundle\Model\Utility;
$x = new Utility(); // FINE!:)
Name of file (Utility.php) must be equal to the class name.
文件名（Utility.php）必须等于类名。

This is what namespaces are for.
这就是命名空间的用途。
From php.net:
来自php.net：
What are namespaces? In the broadest definition namespaces are a way of encapsulating items.
什么是命名空间？在最广泛的定义中，命名空间是一种封装项目的方式。
Simply put, include your namespace at the top of your custom class.
简而言之，将您的命名空间包含在自定义类的顶部。
src/Acme/DemoBundle/Model/MyClass.php
SRC /阿克米/ DemoBundle /型号/ MyClass.php
<?php
namespace Acme\DemoBundle\Model;
class MyClass { // ...
and use it in your Controller:
并在您的控制器中使用它：
src/Acme/SomeOtherBundle/Controller/DefaultController.php
的src / Acme公司/ SomeOtherBundle /控制器/ DefaultController.php
<?php
namespace Acme\SomeOtherBundle\Controller;
// ...
use Acme\DemoBundle\Model\MyClass; # can be used in any class in any bundle
// ...
class DefaultController extends Controller { // ...
