对于APC和Symfony 2.1,app.php应该如何？

Question

我想用symfony 2.1和APC预备app.php文件.我使用Symfony标准版配置了doctrine,然后在此处进行了更改:http: //symfony.com/doc/2.1/book/performance.html

<?php
require_once __DIR__.'\..\vendor\symfony\symfony\src\Symfony\Component\ClassLoader\UniversalClassLoader.php';
require_once __DIR__.'\..\vendor\symfony\symfony\src\Symfony\Component\ClassLoader\ApcUniversalClassLoader.php';
use Symfony\Component\ClassLoader\ApcClassLoader;
use Symfony\Component\HttpFoundation\Request;

$loader = new ApcClassLoader('sf2', $loader);
$loader->register(true);

require_once __DIR__.'/../app/AppKernel.php';
$kernel = new AppKernel('prod', false);
$kernel->loadClassCache();
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);
?>

但它没有用,我得到了错误:

Fatal error: Class 'Symfony\Component\HttpKernel\Kernel' not found in __my_path__\app\AppKernel.php on line 7

我应该如何准备app.php以获得最佳性能.

查看Symfony标准发行版中的默认app.php文件.为了启用APC,您的app.php文件应如下所示:

use Symfony\Component\ClassLoader\ApcClassLoader;
use Symfony\Component\HttpFoundation\Request;

$loader = require_once __DIR__.'/../app/bootstrap.php.cache';

// Use APC for autoloading to improve performance.
// Change 'sf2' to a unique prefix in order to prevent cache key conflicts
// with other applications also using APC.

$loader = new ApcClassLoader('sf2', $loader);
$loader->register(true);

require_once __DIR__.'/../app/AppKernel.php';
//require_once __DIR__.'/../app/AppCache.php';

$kernel = new AppKernel('prod', false);
$kernel->loadClassCache();
//$kernel = new AppCache($kernel);
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);

如果通过取消注释和行启用symfony 网关缓存,还可以提高性能.require_once __DIR__.'/../app/AppCache.php';$kernel = new AppCache($kernel);
