auth check public folder php file?

@coder_uzb I don't know it is possible or not but you may use another way like, You can store file name and user id in one table and from that you can do whatever you want.

@kvithalani. Thank you for reply. But I before checked with this code.

require getcwd() . '/../../../../vendor/autoload.php';
    $app = require_once getcwd() . '/../../../../bootstrap/app.php';

    $kernel = $app->make('Illuminate\Contracts\Http\Kernel');

    $response = $kernel->handle(
        $request = Illuminate\Http\Request::capture()
    );

    $id = $app['encrypter']->decrypt($_COOKIE[$app['config']['session.cookie']]);
    $app['session']->driver()->setId($id);
    $app['session']->driver()->start();
    
    if(!$app['auth']->check()) return false;    
    return true;    

After Laravel 5.5 version, I have following error. unserialize(): Error at offset 0 of 40 bytes.

@coder_uzb Have you run this command after update the version:

php artisan key:generate

if no then please run this command may be your problem will solve....

@kvithalani Yes I runned this command

@coder_uzb okay then run,

composer:dumpautoload 
php artisan config:ca
php artisan cache:cl

@kvithalani I did everything, but did not work

@kvithalani . I fixed problem. I added in App\Http\Middleware\EncryptCookies.php file this code

 protected static $serialize = true;

Take a look at the section on Cookie Serialization in the 5.5 (security release) upgrade guide:

https://laravel.com/docs/5.5/upgrade#upgrade-5.5.42

@CODER_UZB - Just be aware that re-enabling serialization can potentially become a security risk. See my previous post.

Change as like below.

equire getcwd() . '/../../vendor/autoload.php';
    $app = require_once getcwd() . '/../../bootstrap/app.php';
