在Symfony 2.0.x中自动加载非PSR0库 [英] Autoloading non-PSR0 libraries in Symfony 2.0.x

问题描述

Symfony 2.0 Autoloader期望它在自动加载文件时可以处理的库遵循PSR0或PEAR标准.如果您有一个不符合这两个标准中任何一个的旧库(在我的情况下，类文件的名称类似name.class.php)，您将如何处理这些库的自动加载?

The Symfony 2.0 Autoloader expects that the libraries it can handle follow the PSR0 or PEAR standard when auto-loading files. If you have an old library which does not follow any of these two standards (in my case, class files are named like name.class.php), how would you handle auto-loading of these libraries?

在Symfony 2.1中，这很容易，因为composer支持classmaps并且可以加载这种类型的库，但是您将如何在Symfony 2.0.x中实现呢?

In Symfony 2.1 this is easy as composer supports classmaps and can load this type of libraries, but how would you do it in Symfony 2.0.x?

推荐答案

在app/autoload.php内，创建MapClassLoader的实例:

use Symfony\Component\ClassLoader\MapClassLoader;
use Symfony\Component\ClassLoader\UniversalClassLoader;

// Create default PSR-0 autoloader
$loader = new UniversalClassLoader();
$loader->registerNamespaces(array(
    'Symfony' => array(__DIR__.'/../vendor/symfony/src', __DIR__.'/../vendor/bundles'),
    // ...
));

// Create map autoloader
$mapLoader = new MapClassLoader(array(
    'MyComponent' => __DIR__.'/../library/mycomponent.class.php',
    // ...
));

// Other configurations
// ...

// Register autoloaders
$loader->register();
$mapLoader->register();
