How does the Session table records delete itself? - laravel

Question

I'm working with the Session table in Laravel and I just don't see how these records delete themselves after some time.
I haven't found any comprehensive guide on how the Session table works.
Here's my code so far:
SessionHandler.php
<?php
namespace App\Extensions;
class SessionHandler implements \SessionHandlerInterface
{
public function open($savePath, $sessionName) {}
public function close() {}
public function read($sessionId) {}
public function write($sessionId, $data) {}
public function destroy($sessionId) {}
public function gc($lifetime) {}
}
App\Session.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Carbon\Carbon;
class Session extends Model
{
protected $hidden = ['payload'];
/**
* The database table used by the model.
*
* #var string
*/
public $table = 'sessions';
public $timestamps = false;
/**
* Returns the user that belongs to this entry.
*/
public function user()
{
return $this->belongsTo('User');
}
/**
* Returns all the guest users.
*
* #param $query
* #return \Illuminate\Database\Eloquent\Builder
*/
public function scopeGuests($query)
{
return $query->whereNull('user_id')->where('last_activity', '>=', strtotime(Carbon::now()->subMinutes(25)));
}
/**
* Returns all the registered users.
*
* #param $query
* #return \Illuminate\Database\Eloquent\Builder
*/
public function scopeRegistered($query)
{
return $query->whereNotNull('user_id')->where('last_activity', '>=', strtotime(Carbon::now()->subMinutes(25)))->with('user');
}
/**
* Updates the session of the current user.
*
* #param $query
* #return \Illuminate\Database\Eloquent\Builder
*/
public function scopeUpdateCurrent($query)
{
return $query->where('id', Session::getId())->update([
'user_id' => ! empty(Auth::user()) ? Auth::id() : null
]);
}
}
AppServiceProvider.php
Session::extend('handler', function ($app) {
// Return implementation of SessionHandler
return new SessionHandler;
});
.env
SESSION_LIFETIME = 1
session.php
'lifetime' => env('SESSION_LIFETIME', 1),
'expire_on_close' => false,
What I'm basically trying to do is show each Guests/Users activity, but once their session/time limit is over -- POP! It deletes from the database too. Can anyone please share some insight on how to achieve this?

Answer 1

I think I just had to narrow down my search (or search better xD) --
You can set your session.php 'lifetime' value to however long you want the session to last -- and then for the 'lottery' value you can set it to 1,1 so that it fires every time a request is sent (I'm not sure of the performance effect of setting it to this) instead of the default 2,100. You probably should also change .env file SESSION_LIFETIME value to whenever you want it to expire (i.e. 1 for 1 minute).
So after 1 minute, on a request (via 'lottery' firing everytime), it deletes the session records with an expiry time of over one minute.
