The session configuration file is stored at config/session.php. Be sure to review the options available to you in this file. By default, Laravel is configured to use the file session driver, which will work well for many applications.
The session driver configuration option defines where session data will be stored for each request. Laravel ships with several great drivers out of the box:
file - sessions are stored in storage/framework/sessions.cookie - sessions are stored in secure, encrypted cookies.database - sessions are stored in a relational database.memcached / redis - sessions are stored in one of these fast, cache based stores.array - sessions are stored in a PHP array and will not be persisted.
Route::get('form', 'demoController@form');
php artisan make:controller demoController
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
class demoController extends Controller
{
public function form(){
return view('form');
}
}

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\User;
class demoController extends Controller
{
public function form(){
return view('form');
}
public function formstore(Request $request){
return $request->all();

Storing the data in a session
To store the user name in a session, we use the put() method of session as shown below:
$request->session()->put('user', $request->input('username'));
To retrieve the session, we use the get() method of session as shown below:
echo $request->session()->get('user');
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\User;
class demoController extends Controller
{
public function form(){
return view('form');
}
public function formstore(Request $request){
$request->session()->put('user', $request->input('username'));
echo $request->session()->get('user');
}
}
To see output pass below url
http://localhost/laraveldemoproject/public/formstore
Global Session Helper
We can also use the global session function that stores and retrieves the value in a session. When the session function is passed with a single parameter, then it returns the value of the key. If the session is passed with an array of key/value pairs, then the values are stored in the session.
// Retrieve a data from the session key.
$data=session('key');
//Providing a default value to the session key.
$data=session('key', 'default');
// Storing the value in the session key.
session(['key'=>'value']);
For Example:
demoController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\User;
class demoController extends Controller
{
public function form(){
return view('form');
}
public function formstore(Request $request){
session(['user'=>$request->input('username')]);
$data=session('user');
echo $data;
}
}
Retrieving all session data
If we want to retrieve all the session data, then we can use the all() method as shown below:
$session_data = $request->session()->all();
For Example:
demoController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\User;
class demoController extends Controller
{
public function form(){
return view('form');
}
public function formstore(Request $request){
session(['user1'=>'test1']);
session(['user2'=>'test2']);
return $request->session()->all();
}
}
Deleting the session
Now, we will see how to delete the data from the session. We can delete the session by using the forget() method.
For Example:
demoController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\User;
class demoController extends Controller
{
public function form(){
return view('form');
}
public function formstore(Request $request){
session(['user1'=>'test1']);
session(['user2'=>'test2']);
$request->session()->forget('user1');
return $request->session()->all();
}
}
To remove all the data from the session, then we will use the flush() method.
$request->session()->flush();
For Example:
demoController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\User;
class demoController extends Controller
{
public function form(){
return view('form');
}
public function formstore(Request $request){
session(['user1'=>'test1']);
session(['user2'=>'test2']);
$request->session()->flush();
return $request->session()->all();
}
}
Flashing data
Flash data is useful when we want to store the data in the session for the current request as the flashed data is removed in the next request.
For Example:
demoController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\User;
class demoController extends Controller
{
public function form(){
return view('form');
}
public function formstore(Request $request){
session()->flash('post', 'post has been updated');
return $request->session()->get('post');
}
}
When we remove the flash() function from the code, then the code would look like:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\User;
class demoController extends Controller
{
public function form(){
return view('form');
}
public function formstore(Request $request){
return $request->session()->get('post');
}
}
When we refresh the page twice, then on the second refresh, the session data will be deleted.
