Symfony2 会话已经开始 - 忽略 session_start() [英] Symfony2 A session had already been started - ignoring session_start()

问题描述

我无法在本地服务器中使用 Symfony2 会话.我收到通知:会话已经开始 - 忽略 session_start()"错误.

I can't use Symfony2 session in my local server. I'm getting a "Notice: A session had already been started - ignoring session_start()" error.

相同的脚本在我的生产服务器中运行良好.

Same script works fine in my production server.

我在 Windows 7 上使用 Xampp 和 PHP 5.3.5.会话 auto_start 在 php.ini 中关闭.

I'm using Xampp with PHP 5.3.5 over Windows 7. Session auto_start is off in php.ini.

任何提示都会有所帮助.谢谢

Any hint will be helpfull. Thanks

推荐答案

我想这有点晚了，但如果它可以帮助:

I guess it's a bite late but if it can help:

确保您的 php.ini 中的 session.autostart 已关闭 (0)

Make sure your session.autostart is turned off (0) in your php.ini

Symfony 2 中从控制器使用会话的方式如下:

The way to use the session in Symfony 2 from the controler is the following:

$session = $this->getRequest()->getSession();

// store an attribute for reuse during a later user request
$session->set('foo', 'bar');

// in another controller for another request
$foo = $session->get('foo');

// use a default value if the key doesn't exist
$filters = $session->get('filters', array());

http://symfony.com/doc/current/book/controller.html#managing-the-session

或者从视图:

{{ app.session.get('foo') }}

你也应该调用 start() 即使它在你读/写会话数据时被自动调用(因为它是推荐的，例如 getId() 不会调用它)

You should also call start() even if it is automatically called when you read/write session data (because it is recommended and getId() doesn't call it for example)

$session->start();
$id = $session->getId();

http://symfony.com/doc/master/components/http_foundation/session.html

您可能不会在生产服务器上收到错误的原因是它的优先级仅为通知".

The reason you may not get the error on the production server is because it's priority is 'Notice' only.
