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

    namespace App\Http\Controllers;

    use Illuminate\Http\Request;

    use App\Http\Controllers\Controller;

    class StudentRecord extends Controller
       {

    public function logout(Request $req)
        {
     if($req-session()->has('key'){
              $req->session()->forget('key');
        return redirect('/');
              }

//Or simple
    public function logout(Request $req)
        {
     //if($req-session()->has('key')
         $req->session()->flush();
         }


    }


    //Then Do this in your route file
      Route:get("/logout",StudentRecord@logout);

        <a href=" {{ url(logout)}}">logout</a>

Answer 2

You should use this method

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

Answer 3

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

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

Answer 4

Session::forget() does not return true/false. You can just remove your if statement.

As a side note, if you're only using the user key in Session for storing the currently logged in user, you can just use Auth::user() instead.

Answer 5

You can use the Request parameter, containing the current session. This way you can delete any session value by the key:

use Illuminate\Http\Request;

Route::get('/logout', function(Request $request) {
        //Uncomment to see the logs record
        //\Log::info("Session before: ".print_r($request->session()->all(), true));
        if ($request->session()->has('key')) {
           $request->session()->forget('key');
        }
        //Uncomment to see the logs record
        //\Log::info("Session after: ".print_r($request->session()->all(), true));
        return redirect('/');
    });

Or you can delete all values in the session:

use Illuminate\Http\Request;

Route::get('/logout', function(Request $request) {
        //Uncomment to see the logs record
        //\Log::info("Session before: ".print_r($request->session()->all(), true));
        $request->session()->flush();
        //Uncomment to see the logs record
        //\Log::info("Session after: ".print_r($request->session()->all(), true));
        return redirect('/');
    });
