How to delete session in Laravel 5.3 without using Request?

Question

I have a method in a controller that needs to handle the session. That method is called by a get method that doesn't require any user input, so I would like to do it without Request class.

Currently, I am able to set the session, but I cannot find a way to delete it. It looks something like this:

if ($boolean_storing_condition_value)
    session(['some_data'=>'Some Data']);
else
   /* What should be the unset function? */

In Laravel 4.2, it is done with Session::forget('some_data'); or Session::flush(). How should that be done in Laravel 5.3?

Answer 1

You can use the session helper without having to use a request object.

session()->forget('some_data');
session()->flush();

Answer 2

In Laravel 5.3 you still can use flush() and forget() methods:

session()->flush();
session()->forget('key');

Answer 3

add session()->save(); after that.

Answer 4

To delete session variable in Laravel 5.6

session()->forget(['key1']);

to delete the session variables (More the one value delete from the session) use the arguments as arguments session()->forget([' ']);

session()->forget(['key1','key1','key3','...']);
