How to use Zend\Session in zf2?

Question

Does anybody try zf2? I can not understand new mechanism of using sessions in zf2. How can I write and read to/from the session in new zend framework?

Also I can not find any examples in the internet.

Solution 1

Some examples of zf2 sessions usage:

Session creation:

use Zend\Session\Container;
$session = new Container('base');

Check that key exists in session:

$session->offsetExists('email')

Getting value from the session by key:

$email = $session->offsetGet('email');

Setting value in session:

$session->offsetSet('email', $email);

Unsetting value in session:

$session->offsetUnset('email');

And other easy way to use session are:

$session = new Container('foo');

// these are all equivalent means to the same end

$session['bar'] = 'foobar';

$session->bar = 'foobar';

$session->offsetSet('bar', 'foobar'); 

Solution 2

Definitely yes, you should use Zend\Session\Container

Container extends of ArrayObject and instantiates with ARRAY_AS_PROPS flag that means you can easily iterate through properties and read/write them, e.g.

use Zend\Session\Container as SessionContainer;

$this->session = new SessionContainer('post_supply');
$this->session->ex = true;
var_dump($this->session->ex);

First argument is session namespace and second — Manager. Manager is a facade for Storage and SaveHandler and it's configured with ConfigInterface in order to save your session data in DB or Memcache server.

Solution 3

I'm currently working with zf2. I found usage of Sessions in:

Zend\Authentication\Storage\Session.php

Maybe you can find your answer there.

Solution 4

If you are trying to use session in your login action, you can use: "Zend\Authentication\AuthenticationService". It Authenticates the user and store session as well.

getStorage()->write($contents) will store the session.
