Symfony2 Session as Entity / Clearing old sessions without remember me - php

Question

how i can use the $sessData, which is a blob?
Example entity
<?php
namespace Acme\DemoBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Session
*
* #ORM\Table(name="sessions")
* #ORM\Entity
*/
class Session
{
/**
* #var string
*
* #ORM\Column(name="sess_id", type="string", length=128)
* #ORM\Id
* #ORM\GeneratedValue(strategy="IDENTITY")
*/
private $sessId;
/**
* #var string
*
* #ORM\Column(name="sess_data", type="blob", length=65535, nullable=false)
*/
private $sessData;
/**
* #var integer
*
* #ORM\Column(name="sess_time", type="integer", nullable=false, options={"unsigned"=true})
*/
private $sessTime;
/**
* #var integer
*
* #ORM\Column(name="sess_lifetime", type="integer", nullable=false)
*/
private $sessLifetime;
}
Example command.
<?php
namespace Acme\UserBundle\Command;
use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Acme\UserBundle\Entity\Session;
/**
* Class ClearSessionsCommand
* #package Acme\UserBundle\Command
*/
class ClearSessionsCommand extends ContainerAwareCommand
{
protected function configure()
{
$this
->setName('acme:clear:sessions')
->setDescription('Deletes old sessions from database')
;
}
protected function execute(InputInterface $input, OutputInterface $output)
{
/** #var \Doctrine\Bundle\DoctrineBundle\Registry $doctrine */
$doctrine = $this->getContainer()->get('doctrine');
$repository = $doctrine->getManager()->getRepository('AcmeUserBundle:Session');
$sessions = $repository->findAll();
foreach($sessions as $session)
{
/** #var Session $session */
var_dump($session->getSessData());
}
}
}
And that's the output.
class Acme\UserBundle\Entity\Session#460 (4) {
private $sessId => string(26) "5v0as58i11vgikih7rb0b7fg41"
private $sessData => resource(419) of type (stream)
private $sessTime => int(1421508757)
private $sessLifetime => int(1440)
}
I'll hope you can help me.
I also tried to use "array", "simple_array" and "json_array".
But if i view the value in plain text i have a format like this.
_sf2_attributes|a:2:{s:18:"_csrf/authenticate";s:43:"esEvNzkJgkPN3JcgVWO71ArAHnoMxK_ChC1qdXT4bM4";s:14:"_security_main";s:691:"C:74:"Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken":603:{a:3:{i:0;N;i:1;s:4:"main";i:2;s:563:"a:4:{i:0;C:26:"Acme\UserBundle\Entity\User":227:{a:9:{i:0;s:88:"4T+akBl30pcGyIDl3MB64TT/o4izQZ/CA/JDHurok50o33g3L0bEgDYMj+itI5G6JWQmzH7gHTrDmLeE7I9yeQ==";i:1;s:31:"cljvnnze8jwo8ck4og8gcg08c4o0ww4";i:2;s:8:"max";i:3;s:8:"Max";i:4;b:0;i:5;b:0;i:6;b:0;i:7;b:1;i:8;i:1;}}i:1;b:1;i:2;a:2:{i:0;O:41:"Symfony\Component\Security\Core\Role\Role":1:{s:47:"
And i dont know whats this could be for a format.
If i remove _sf2_attributes| it might be serialized.
I would delete all sessions where older than one day and not logged in with remembered option.
Thanks in Advance!
