如何在Symfony中使用Sessions？

Like in classic PHP we use the magic variables to start and create sessions, so how to do that in Symfony?

与经典PHP一样，我们使用魔术变量来启动和创建会话，那么如何在Symfony中执行此操作？

2 个解决方案

#1

In your controller, you can access session variables through the user object.

在控制器中，您可以通过用户对象访问会话变量。

// Get a session value
$name = $this->getUser()->getAttribute('name', 'default_value');
// Set a session value
$this->getUser()->setAttribute('name', $value);

#2

In Symfony2, the syntax is different:

在Symfony2中，语法不同：

$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');

You can also get session variables from Twig, without having to pass the session variable explicitly (it's in the global 'app'):

您还可以从Twig获取会话变量，而无需显式传递会话变量（它位于全局“app”中）：

{{ app.session.get('foo', 'bar'); }}
