require '/path/to/laravel/bootstrap/autoload.php';
$app = require_once '/path/to/laravel/bootstrap/start.php';

$request = $app['request'];
$client = (new \Stack\Builder)
            ->push('Illuminate\Cookie\Guard', $app['encrypter'])
            ->push('Illuminate\Cookie\Queue', $app['cookie'])
            ->push('Illuminate\Session\Middleware', $app['session'], null);
$stack = $client->resolve($app);
$stack->handle($request);

$isAuthorized = Auth::check();

Laravel 5.4

require '/var/www/vhosts/xx.xxx.com/bootstrap/autoload.php';

$app = require_once '/var/www/vhosts/xxx.xxx.com/bootstrap/app.php';

$app->make('Illuminate\Contracts\Http\Kernel')->handle(Illuminate\Http\Request::capture());

$id = $app['encrypter']->decrypt($_COOKIE[$app['config']['session.cookie']]);

$session = $app['session']->driver();
$session->setId($id);
$session->start();

$isAuthenticated = $app['auth']->check();

if($isAuthenticated) {
echo 'logged in';
} else {
echo 'not';
}

I can get the laravel session data using above code to any PHP file.

@Developers-account Don't work mate. $app->make('Illuminate\Contracts\Http\Kernel') is throwing a fit with the following error. "Call to a member function make() on boolean"

I need to understand Laravel indepth.

Laravel 5.5

require __DIR__.'/../../../vendor/autoload.php';
$app = require __DIR__.'/../../../bootstrap/app.php';

$app->make('Illuminate\Contracts\Http\Kernel')
    ->handle(Illuminate\Http\Request::capture());

$value = Session::get("any key");

Laravel 8

I work in a docker environement, and because i use redis as the session driver and not file i had to intall php redis extension.
I also got a database error connection, to fix it, i installed the pdo_mysql php extension.

`

  include $_SERVER['DOCUMENT_ROOT'].'/../../vendor/autoload.php';

  $app = include $_SERVER['DOCUMENT_ROOT'].'/../../bootstrap/app.php';

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

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

  $id = (isset($_COOKIE[$app['config']['session.cookie']]) ? $app['encrypter']->decrypt($_COOKIE[$app['config']['session.cookie']], false) : null);

  if ($id) {
      $app['session']->driver()->setId(explode('|', $id)[1]);
      $app['session']->driver()->start();

      // Session::all()
      // $app['auth']->getSession() //  Illuminate\Session\Store
      // Auth::user()
      // $app['auth']->user()
  } else {
      var_dump('NO SESSION ID');
  }

`

The above solution works for Laravel 5.5

Laravel 7
Hello, help me please.
I added CKFinder to the admin panel in the articles section, and I want to make access only for the logged-in administrator when I remove exit (); function everything works there is a loading of images adding folders, but exit (); gives an error (Invalid request), but without exit (); I understand that it is not safe.:((
Thank you in advance for your help!

$config['authentication'] = function () {
    require $_SERVER['DOCUMENT_ROOT'] . '/vendor/autoload.php';
    $app = require_once  $_SERVER['DOCUMENT_ROOT']. '/bootstrap/app.php';
    $response = $app->make('Illuminate\Contracts\Http\Kernel')->handle(Illuminate\Http\Request::capture());
    $cookie = $_COOKIE[$app['config']['session']['cookie']] ?? false;
    if ($cookie) {
        $id = $app['encrypter']->decrypt($cookie, false);
        $session = $app['session']->driver();
        $session->setId($id);
        $session->start();
    }
    if (!$app['auth']->check() || !$app['auth']->user()->is_admin){
        header('HTTP/1.0 403 Forbidden'); exit();
    }
    return true;
};

The solution above for 5.2 should still work. In 5.5+ you just need to change bootstrap/autoload.php to vendor/autoload.php.

<?php

require '/path/to/laravel/vendor/autoload.php';
$app = require_once '/path/to/laravel/bootstrap/app.php';

$app->make('Illuminate\Contracts\Http\Kernel')
    ->handle(Illuminate\Http\Request::capture());

// An instance of the Laravel app should be now at your fingertip ;-)

...

$isAuthorized = Auth::check();

How can we achieve this if both applications are on different servers?

Laravel 5.5

require __DIR__.'/../../../vendor/autoload.php';
$app = require __DIR__.'/../../../bootstrap/app.php';

$app->make('Illuminate\Contracts\Http\Kernel')
    ->handle(Illuminate\Http\Request::capture());

$value = Session::get("any key");

Use Session::all() to see what keys are available:

    $value = Session::all();
    echo "<pre>";
    print_r($value);
    echo "<pre>";

But in 5.5 I am still getting empty array for Session and for Auth ... so not pulling the session over for some reason :(

Anyone an idea for a laravel 11 project?
