php - APC 和 Symfony 2.1 的 app.php 应该是什么样子

Question

我想用 Symfony 2.1 和 APC 准备 app.php 文件。我使用 Symfony 标准版对其进行了教义配置，然后进行了此处描述的更改：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);
?>

但它不起作用，我收到错误：

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 标准发行版中默认的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来启用 symfony网关缓存，还可以提高性能。require_once __DIR__.'/../app/AppCache.php';$kernel = new AppCache($kernel);
