session variable in laravel

Sessions are used to store information about the user across the requests. Laravel provides various drivers like file, cookie, apc, array, Memcached, Redis, and database to handle session data. By default, file driver is used because it is lightweight. Session can be configured in the file stored at config/session.php.

$value = $request->session()->get('key');

$request->session()->put('key', 'value');

$request->session()->forget('key');
