使用Symfony 1.4的自动加载器加载命名空间类吗?

问题描述：

如何在Symfony 1.4中为自动加载器类功能注册名称空间(使用PHP 5.3)(例如 Symfony 2.0 )?

How to register namespaces (with PHP 5.3) in the Symfony 1.4 for the autoloader class feature (like the Symfony 2.0)?

答

您可以在Symfony 1.4框架中使用来自Symfony2的自动加载器.

You can use Autoloader from Symfony2 in Symfony 1.4 framework.

1.将Symfony2类加载器复制到Symfony 1.4沙箱项目的供应商目录中:

SF_ROOT_DIR/lib/vendor/Symfony2/src/Symfony/Component/ClassLoader/UniversalClassLoader.php

SF_ROOT_DIR/lib/vendor/Symfony2/src/Symfony/Component/ClassLoader/ApcUniversalClassLoader.php

2.修改您的SF_ROOT_DIR/config/ProjectConfiguration.class.php文件，如下所示:

require_once dirname(__FILE__) . '/../lib/vendor/symfony/lib/autoload/sfCoreAutoload.class.php';
require_once dirname(__FILE__) . '/../lib/autoload/sfClassLoader.class.php';
sfCoreAutoload::register();

class ProjectConfiguration extends sfProjectConfiguration {

    public function setup() {
        $this->namespacesClassLoader();
        $this->enablePlugins('sfDoctrinePlugin');
    }

    public function namespacesClassLoader() {
       if (extension_loaded('apc')) {
           $loader = new ApcUniversalClassLoader('S2A');
       } else {
           $loader = new UniversalClassLoader();
       }
       $loader->registerNamespaces(array(
          'Pohon' => __DIR__ . '/../lib/vendor/Pohon/src'));
       $loader->register();
    }

}

3.注册所需的名称空间:
例如.我要加载课程:

3. Register desired namespaces:
eg. I want to load class:

Pohon \ Tools \ String \ Utils \ Slugify.

Pohon\Tools\String\Utils\Slugify.

文件名必须为:

SF_ROOT_DIR/lib/vendor/Pohon/src/Pohon/Tools/String/Utils/Slugify.php

和注册的名称空间如下:

and registered namespace as follows:

Pohon => SF_ROOT_DIR/lib/vendor/Pohon/src

使用Symfony 1.4的自动加载器加载命名空间类吗?
