how to remove sessions in Laravel 5

Question

I am trying to remove a basic session but it's not removing. Here's the code

welcome.blade.php

@if(Session::has('key'))             
    {{ Session::get('key')}}
    <a href="logout">Sign Out</a>

    @else
        please signin

    @endif
</div>

I don't know how to remove session. Here's the one I used but it's not working route.php

Route::get('/logout', function() {

   $vv =  Session::forget('key');
   if($vv)
   {
        return "signout";
   }
});

Answer 1

You should use this method

 Route::get('/logout', function() {
 Session::forget('key');
  if(!Session::has('key'))
   {
      return "signout";
   }
 });

Answer 2

You can try with Session::pull('key');

And if you want to delete all sessions variable you can use Session::flush();
