laravel middleware array_key_exists() error

Question

My middleware code
php version 5.6.32-1

<?php

namespace App\Http\Middleware;
use Session, Closure;

class AuthLogin
{
    public function handle($request, Closure $next)
    {
        if (!Session::has('account')) {
          return redirect('/admin/login');
        }

        return $next($request);
    }
}

And I get this error

array_key_exists(): The first argument should be either a string or an integer

what's happend with it?

There is not any error on my mac, but it's happen on my linode server

You are getting this error due to the following reason :

$arr = [[0] => 10,[1] => 20,[2] => 30,[3] => 40,[4] => 50];

let's say you search for values 10 or 30

$k = array_search('10', $arr);

now $k will hold [0]

and if do this

array_key_exists($k, $arr);

you will get array_key_exists(): The first argument should be either a string or an integer because $k i,e 0 is treated as boolean not string or int but if we have searched 30 then this issue will not occur.

For anyone who facing this problem, I solved this by clearing config cache using:

 php artisan config:clear

or also you can using command (this will clear all cache in your application, including route, config, view and app cache):

php artisan optimize:clear

And this is how I check if session exist:

 public function handle($request, Closure $next)
    {
        if (!$request->session()->exists('session_name')) {
            return redirect('/');
        }

        return $next($request);
    }
