How to use Zend\Session in zf2? - php

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.

Answer 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');

Answer 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.

Answer 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.

Answer 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.

Answer 5

well here is the brief example. i have implemented regarding maintaining session on successful authentication of user.
<?php
$registry = Zend_Registry::getInstance();
$DB = $registry['DB'];
$authAdapter = new Zend_Auth_Adapter_DbTable($DB);
$authAdapter->setTableName('user');
$authAdapter->setIdentityColumn("user_name");
$authAdapter->setCredentialColumn("user_password");
//get values
$username = $request->getParam('username');
$password = $request->getParam('password');
//set values
$authAdapter->setIdentity($username);
$authAdapter->setCredential($password);
$auth = Zend_Auth::getInstance();
//to store in session
$auth->setStorage(new Zend_Auth_Storage_Session('front'));
$authResult = $auth->authenticate($authAdapter);
if ($authResult->isValid()) {
$authAdap = $authAdapter->getResultRowObject(null, "Password");
$auth->getStorage()->write($authAdap);
$this->_redirect('/login/controlpannel');
} else {
$this->_redirect('/login/login');
}
?>
getting values or check data stored in session related to user
<?php
$auth = Zend_Auth::getInstance();
$auth->setStorage(new Zend_Auth_Storage_Session('front'));
if($auth->hasIdentity()){
$data = $auth->getStorage()->read();
print_r($data);
}else{
$this->_redirect('/login/login');
}
?>
hope this could help someone

use Zend\Session\Container;
public function createAction(){
$session = new Container('name');
$session->offsetSet('session_variable', $value);
}
//the above codes are used for create session.
public function take_valuesAction(){
$session = new Container('name');
echo $value = $session->offsetGet('session_variable');
}
//the above codes are used for take values from session.
public function destroyAction(){
$session = new Container('name');
$session->getManager()->destroy();
}
//the above codes are used for destroy the session.

To start a session you need to use
zend\session\container
