Retrieving Data

#Via Request

// ...
class UserController extends Controller
{
    public function show(Request $request, $id)
 {
        $value = $request->session()->get('key');
        //
    }
}

Pass a default value as the second argument to use if the key does not exist

$value = $request->session()->get('key', 'default');
// closure can be passed and executed as a default
$value = $request->session()->get('key', function () {
    return 'default';
});

#Via session helper

Route::get('/home', function () {
    // Retrieve a piece of data from the session...
    $value = session('key');
    // Specifying a default value...
    $value = session('key', 'default');
    // Store a piece of data in the session...
    session(['key' => 'value']);
});

See: Session Helper
